mm/memremap: Pass down MEMREMAP_* flags to arch_memremap_wb()
x86 version of arch_memremap_wb() needs the flags to decide if the mapping has to be encrypted or decrypted. Pass down the flag to arch_memremap_wb(). All current implementations ignore the argument.

Driver core api addition for 6.14-rc3
Here is a driver core new api for 6.14-rc3 that is being added to allow platform devices from stop being abused. It adds a new "faux_device" structure and bus and api to allow almost a straight or simpler conversion from platform devices that were not really a platform device. It also comes with a binding for rust, with an example driver in rust showing how it's used. I'm adding this now so that the patches that convert the different drivers and subsystems can all start flowing into linux-next now through their different development trees, in time for 6.15-rc1. We have a number that are already reviewed and tested, but adding those conversions now doesn't seem right. For now, no one is using this, and it passes all build tests from 0-day and linux-next, so all should be good.

ARM:
- Large set of fixes for vector handling, specially in the interactions
between host and guest state. This fixes a number of bugs affecting
actual deployments, and greatly simplifies the FP/SIMD/SVE handling.
Thanks to Mark Rutland for dealing with this thankless task.
- Fix an ugly race between vcpu and vgic creation/init, resulting in
unexpected behaviours.
- Fix use of kernel VAs at EL2 when emulating timers with nVHE.
- Small set of pKVM improvements and cleanups.
x86:
- Fix broken SNP support with KVM module built-in, ensuring the PSP
module is initialized before KVM even when the module infrastructure
cannot be used to order initcalls
- Reject Hyper-V SEND_IPI hypercalls if the local APIC isn't being emulated
by KVM to fix a NULL pointer dereference.
- Enter guest mode (L2) from KVM's perspective before initializing the vCPU's
nested NPT MMU so that the MMU is properly tagged for L2, not L1.
- Load the guest's DR6 outside of the innermost .vcpu_run() loop, as the
guest's value may be stale if a VM-Exit is handled in the fastpath.

Ring buffer fixes for v6.14:
- Enable resize on mmap() error When a process mmaps a ring buffer, its size is locked and resizing is disabled. But if the user passes in a wrong parameter, the mmap() can fail after the resize was disabled and the mmap() exits with error without reenabling the ring buffer resize. This prevents the ring buffer from ever being resized after that. Reenable resizing of the ring buffer on mmap() error. - Have resizing return proper error and not always -ENOMEM If the ring buffer is mmapped by one task and another task tries to resize the buffer it will error with -ENOMEM. This is confusing to the user as there may be plenty of memory available. Have it return the error that actually happens (in this case -EBUSY) where the user can understand why the resize failed. - Test the sub-buffer array to validate persistent memory buffer On boot up, the initialization of the persistent memory buffer will do a validation check to see if the content of the data is valid, and if so, it will use the memory as is, otherwise it re-initializes it. There's meta data in this persistent memory that keeps track of which sub-buffer is the reader page and an array that states the order of the sub-buffers. The values in this array are indexes into the sub-buffers. The validator checks to make sure that all the entries in the array are within the sub-buffer list index, but it does not check for duplications. While working on this code, the array got corrupted and had duplicates, where not all the sub-buffers were accounted for. This passed the validator as all entries were valid, but the link list was incorrect and could have caused a crash. The corruption only produced incorrect data, but it could have been more severe. To fix this, create a bitmask that covers all the sub-buffer indexes and set it to all zeros. While iterating the array checking the values of the array content, have it set a bit corresponding to the index in the array. If the bit was already set, then it is a duplicate and mark the buffer as invalid and reset it. - Prevent mmap()ing persistent ring buffer The persistent ring buffer uses vmap() to map the persistent memory. Currently, the mmap() logic only uses virt_to_page() to get the page from the ring buffer memory and use that to map to user space. This works because a normal ring buffer uses alloc_page() to allocate its memory. But because the persistent ring buffer use vmap() it causes a kernel crash. Fixing this to work with vmap() is not hard, but since mmap() on persistent memory buffers never worked, just have the mmap() return -ENODEV (what was returned before mmap() for persistent memory ring buffers, as they never supported mmap. Normal buffers will still allow mmap(). Implementing mmap() for persistent memory ring buffers can wait till the next merge window. - Fix polling on persistent ring buffers There's a "buffer_percent" option (default set to 50), that is used to have reads of the ring buffer binary data block until the buffer fills to that percentage. The field "pages_touched" is incremented every time a new sub-buffer has content added to it. This field is used in the calculations to determine the amount of content is in the buffer and if it exceeds the "buffer_percent" then it will wake the task polling on the buffer. As persistent ring buffers can be created by the content from a previous boot, the "pages_touched" field was not updated. This means that if a task were to poll on the persistent buffer, it would block even if the buffer was completely full. It would block even if the "buffer_percent" was zero, because with "pages_touched" as zero, it would be calculated as the buffer having no content. Update pages_touched when initializing the persistent ring buffer from a previous boot. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZ7DtcxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qmTQAQD1W/xHfS8yLw7BQBjM+6kqExdrKI/D Z378Et0LSWjZBQD/VtPKiSjLhhNgLUBy5fAWS5t4X/DZ49GKhTA36AzGHwE= =1b+2 -----END PGP SIGNATURE----- Merge tag 'trace-ring-buffer-v6.14-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull trace ring buffer fixes from Steven Rostedt: - Enable resize on mmap() error When a process mmaps a ring buffer, its size is locked and resizing is disabled.

ring-buffer: Update pages_touched to reflect persistent buffer content
The pages_touched field represents the number of subbuffers in the ring
buffer that have content that can be read. This is used in accounting of
"dirty_pages" and "buffer_percent" to allow the user to wait for the
buffer to be filled to a certain amount before it reads the buffer in
blocking mode.
The persistent buffer never updated this value so it was set to zero, and
this accounting would take it as it had no content. This would cause user
space to wait for content even though there's enough content in the ring
buffer that satisfies the buffer_percent.

The reason was that the code that maps the ring buffer pages to user space
has:
page = virt_to_page((void *)cpu_buffer->subbuf_ids[s]);
And uses that in:
vm_insert_pages(vma, vma->vm_start, pages, &nr_pages);
But virt_to_page() does not work with vmap()'d memory which is what the
persistent ring buffer has. It is rather trivial to allow this, but for
now just disable mmap() of instances that have their ring buffer from the
reserve_mem option.
If an mmap() is performed on a persistent buffer it will return -ENODEV
just like it would if the .mmap field wasn't defined in the
file_operations structure.

kbuild: userprogs: fix bitsize and target detection on clang
scripts/Makefile.clang was changed in the linked commit to move --target from
KBUILD_CFLAGS to KBUILD_CPPFLAGS, as that generally has a broader scope.
However that variable is not inspected by the userprogs logic,
breaking cross compilation on clang.
Use both variables to detect bitsize and target arguments for userprogs.

tegra210-adma: fix 32-bit x86 build
The Tegra210 Audio DMA controller driver did a plain divide: page_no = (res_page->start - res_base->start) / cdata->ch_base_offset; which causes problems on 32-bit x86 configurations that have 64-bit resource sizes: x86_64-linux-ld: drivers/dma/tegra210-adma.o: in function `tegra_adma_probe': tegra210-adma.c:(.text+0x1322): undefined reference to `__udivdi3' because gcc doesn't generate the trivial code for a 64-by-32 divide, turning it into a function call to do a full 64-by-64 divide. And the kernel intentionally doesn't provide that helper function, because 99% of the time all you want is the narrower version. Of course, tegra210 is a 64-bit architecture and the 32-bit x86 build is purely for build testing, so this really is just about build coverage failure. But build coverage is good. Side note: div_u64() would be suboptimal if you actually have a 32-bit resource_t, so our "helper" for divides are admittedly making it harder than it should be to generate good code for all the possible cases. At some point, I'll consider 32-bit x86 so entirely legacy that I can't find it in myself to care any more, and we'll just add the __udivdi3 library function. But for now, the right thing to do is to use "div_u64()" to show that you know that you are doing the simpler divide with a 32-bit number. And the build error enforces that. While fixing the build issue, also check for division-by-zero, and for overflow. Which hopefully cannot happen on real production hardware, but the value of 'ch_base_offset' can definitely be zero in other places.

tools: fix annoying "mkdir -p ..." logs when building tools in parallel
When CONFIG_OBJTOOL=y or CONFIG_DEBUG_INFO_BTF=y, parallel builds
show awkward "mkdir -p ..." logs.
$ make -j16
[ snip ]
mkdir -p /home/masahiro/ref/linux/tools/objtool && make O=/home/masahiro/ref/linux subdir=tools/objtool --no-print-directory -C objtool
mkdir -p /home/masahiro/ref/linux/tools/bpf/resolve_btfids && make O=/home/masahiro/ref/linux subdir=tools/bpf/resolve_btfids --no-print-directory -C bpf/resolve_btfids
Defining MAKEFLAGS=<value> on the command line wipes out command line
switches from the resultant MAKEFLAGS definition, even though the command
line switches are active. [1]
MAKEFLAGS puts all single-letter options into the first word, and that
word will be empty if no single-letter options were given. [2]
However, this breaks if MAKEFLAGS=<value> is given on the command line.
The tools/ and tools/% targets set MAKEFLAGS=<value> on the command
line, which breaks the following code in tools/scripts/Makefile.include:
short-opts := $(firstword -$(MAKEFLAGS))
If MAKEFLAGS really needs modification, it should be done through the
environment variable, as follows:
MAKEFLAGS=<value> $(MAKE) ...
That said, I question whether modifying MAKEFLAGS is necessary here.
The only flag we might want to exclude is --no-print-directory, as the
tools build system changes the working directory. However, people might
find the "Entering/Leaving directory" logs annoying.
I simply removed the offending MAKEFLAGS=<value>.

x86/sev: Fix broken SNP support with KVM module built-in
Fix issues with enabling SNP host support and effectively SNP support
which is broken with respect to the KVM module being built-in.
SNP host support is enabled in snp_rmptable_init() which is invoked as
device_initcall(). SNP check on IOMMU is done during IOMMU PCI init
(IOMMU_PCI_INIT stage). And for that reason snp_rmptable_init() is
currently invoked via device_initcall() and cannot be invoked via
subsys_initcall() as core IOMMU subsystem gets initialized via
subsys_initcall().
Now, if kvm_amd module is built-in, it gets initialized before SNP host
support is enabled in snp_rmptable_init() :
[ 10.131811] kvm_amd: TSC scaling supported
[ 10.136384] kvm_amd: Nested Virtualization enabled
[ 10.141734] kvm_amd: Nested Paging enabled
[ 10.146304] kvm_amd: LBR virtualization supported
[ 10.151557] kvm_amd: SEV enabled (ASIDs 100 - 509)
[ 10.156905] kvm_amd: SEV-ES enabled (ASIDs 1 - 99)
[ 10.162256] kvm_amd: SEV-SNP enabled (ASIDs 1 - 99)
[ 10.171508] kvm_amd: Virtual VMLOAD VMSAVE supported
[ 10.177052] kvm_amd: Virtual GIF supported
...
...
[ 10.201648] kvm_amd: in svm_enable_virtualization_cpu
And then svm_x86_ops->enable_virtualization_cpu()
(svm_enable_virtualization_cpu) programs MSR_VM_HSAVE_PA as following:
wrmsrl(MSR_VM_HSAVE_PA, sd->save_area_pa);
So VM_HSAVE_PA is non-zero before SNP support is enabled on all CPUs.
snp_rmptable_init() gets invoked after svm_enable_virtualization_cpu()
as following :
...
[ 11.256138] kvm_amd: in svm_enable_virtualization_cpu
...
[ 11.264918] SEV-SNP: in snp_rmptable_init
This triggers a #GP exception in snp_rmptable_init() when snp_enable()
is invoked to set SNP_EN in SYSCFG MSR:

This #GP exception is getting triggered due to the following errata for
AMD family 19h Models 10h-1Fh Processors:
Processor may generate spurious #GP(0) Exception on WRMSR instruction:
Description:
The Processor will generate a spurious #GP(0) Exception on a WRMSR
instruction if the following conditions are all met:
- the target of the WRMSR is a SYSCFG register.
- the write changes the value of SYSCFG.SNPEn from 0 to 1.
- One of the threads that share the physical core has a non-zero
value in the VM_HSAVE_PA MSR.
The document being referred to above:
https://www.amd.com/content/dam/amd/en/documents/processor-tech-docs/revision-guides/57095-PUB_1_01.pdf
To summarize, with kvm_amd module being built-in, KVM/SVM initialization
happens before host SNP is enabled and this SVM initialization
sets VM_HSAVE_PA to non-zero, which then triggers a #GP when
SYSCFG.SNPEn is being set and this will subsequently cause
SNP_INIT(_EX) to fail with INVALID_CONFIG error as SYSCFG[SnpEn] is not
set on all CPUs.
Essentially SNP host enabling code should be invoked before KVM
initialization, which is currently not the case when KVM is built-in.
Add fix to call snp_rmptable_init() early from iommu_snp_enable()
directly and not invoked via device_initcall() which enables SNP host
support before KVM initialization with kvm_amd module built-in.
Add additional handling for `iommu=off` or `amd_iommu=off` options.
Note that IOMMUs need to be enabled for SNP initialization, therefore,
if host SNP support is enabled but late IOMMU initialization fails
then that will cause PSP driver's SNP_INIT to fail as IOMMU SNP sanity
checks in SNP firmware will fail with invalid configuration error as
below:
[ 9.723114] ccp 0000:23:00.1: sev enabled
[ 9.727602] ccp 0000:23:00.1: psp enabled

KVM: SVM: Ensure PSP module is initialized if KVM module is built-in
The kernel's initcall infrastructure lacks the ability to express dependencies between initcalls, whereas the modules infrastructure automatically handles dependencies via symbol loading. Ensure the PSP SEV driver is initialized before proceeding in sev_hardware_setup() if KVM is built-in as the dependency isn't handled by the initcall infrastructure.

crypto: ccp: Add external API interface for PSP module initialization
KVM is dependent on the PSP SEV driver and PSP SEV driver needs to be loaded before KVM module. In case of module loading any dependent modules are automatically loaded but in case of built-in modules there is no inherent mechanism available to specify dependencies between modules and ensure that any dependent modules are loaded implicitly. Add a new external API interface for PSP module initialization which allows PSP SEV driver to be loaded explicitly if KVM is built-in.

alpha: make stack 16-byte aligned (most cases)
The problem is that GCC expects 16-byte alignment of the incoming stack
since early 2004, as Maciej found out [1]:
Having actually dug speculatively I can see that the psABI was changed in
GCC 3.5 with commit e5e10fb4a350 ("re PR target/14539 (128-bit long double
improperly aligned)") back in Mar 2004, when the stack pointer alignment
was increased from 8 bytes to 16 bytes, and arch/alpha/kernel/entry.S has
various suspicious stack pointer adjustments, starting with SP_OFF which
is not a whole multiple of 16.
Also, as Magnus noted, "ALPHA Calling Standard" [2] required the same:
D.3.1 Stack Alignment
This standard requires that stacks be octaword aligned at the time a
new procedure is invoked.
However:
- the "normal" kernel stack is always misaligned by 8 bytes, thanks to
the odd number of 64-bit words in 'struct pt_regs', which is the very
first thing pushed onto the kernel thread stack;
- syscall, fault, interrupt etc. handlers may, or may not, receive aligned
stack depending on numerous factors.
Somehow we got away with it until recently, when we ended up with
a stack corruption in kernel/smp.c:smp_call_function_single() due to
its use of 32-byte aligned local data and the compiler doing clever
things allocating it on the stack.
This adds padding between the PAL-saved and kernel-saved registers
so that 'struct pt_regs' have an even number of 64-bit words.
This makes the stack properly aligned for most of the kernel
code, except two handlers which need special threatment.
Note: struct pt_regs doesn't belong in uapi/asm; this should be fixed,
but let's put this off until later.

ring-buffer: Validate the persistent meta data subbuf array
The meta data for a mapped ring buffer contains an array of indexes of all
the subbuffers. The first entry is the reader page, and the rest of the
entries lay out the order of the subbuffers in how the ring buffer link
list is to be created.
The validator currently makes sure that all the entries are within the
range of 0 and nr_subbufs. But it does not check if there are any
duplicates.
While working on the ring buffer, I corrupted this array, where I added
duplicates. The validator did not catch it and created the ring buffer
link list on top of it. Luckily, the corruption was only that the reader
page was also in the writer path and only presented corrupted data but did
not crash the kernel. But if there were duplicates in the writer side,
then it could corrupt the ring buffer link list and cause a crash.
Create a bitmask array with the size of the number of subbuffers. Then
clear it. When walking through the subbuf array checking to see if the
entries are within the range, test if its bit is already set in the
subbuf_mask. If it is, then there is duplicates and fail the validation.
If not, set the corresponding bit and continue.
