emulator in favor of int3_emulate_jcc() which is written in C - Replace KVM fastops with C-based stubs which avoids problems with the fastop infra related to latter not adhering to the C ABI due to their special calling convention and, more importantly, bypassing compiler control-flow integrity checking because they're written in asm - Remove wrongly used static branches and other ugliness accumulated over time in hyperv's hypercall implementation with a proper static function call to the correct hypervisor call variant - Add some fixes and modifications to allow running FRED-enabled kernels in KVM even on non-FRED hardware - Add kCFI improvements like validating indirect calls and prepare for enabling kCFI with GCC. Add cmdline params documentation and other code cleanups - Use the single-byte 0xd6 insn as the official #UD single-byte undefined opcode instruction as agreed upon by both x86 vendors - Other smaller cleanups and touchups all over the place -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEzv7L6UO9uDPlPSfHEsHwGGHeVUoFAmjqXxkACgkQEsHwGGHe VUq9QBAAsjaay99a1+Dc53xyP1/HzCUFZDOzEYhj9zF85I8/xA9vTXZr7Qg2m6os +4EEmnlwU43AR5KgwGJcuszLF9qSqTMz5qkAdFpvnoQ1Hbc8b49A+3yo9/hM7NA2 gPGH0gVZVBcffoETiQ8tJN6C9H6Ec0nTZwKTbasWwxz5oUAw+ppjP+aF4rFQ2/5w b1ofrcga5yucjvSlXjBOEwHvd21l7O9iMre1oGEn6b0E2LU8ldToRkJkVZIhkWeL 2Iq3gYtVNN4Ao06WbV/EfXAqg5HWXjcm5bLcUXDtSF+Blae+gWoCjrT7XQdQGyEq J12l4FbIZk5Ha8eWAC425ye9i3Wwo+oie3Cc4SVCMdv5A+AmOF0ijAlo1hcxq0rX eGNWm8BKJOJ9zz1kxLISO7CfjULKgpsXLabF5a19uwoCsQgj5YrhlJezaIKHXbnK OWwHWg9IuRkN2KLmJa7pXtHkuAHp4MtEV9TP9kU2WCvCInrNrzp3gYtds3pri82c 8ove+WA3yb/AQ6RCq5vAMLYXBxMRbN7FrmY5ZuwgWJTMi6cp1Sp02mhobwJOgNhO H7nKWCZnQMyCLPzVeg97HTSgqSXw13dSrujWX9gWYVWBMfZO1B9HcUrhtiOhH7Q9 cvELkcqaxKrCKdRHLLYgHeMIQU2tdpsQ5TXHm7C7liEcZPZpk+g= =3Otb -----END PGP SIGNATURE----- Merge tag 'x86_core_for_v6.18_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull more x86 updates from Borislav Petkov: - Remove a bunch of asm implementing condition flags testing in KVM's emulator in favor of int3_emulate_jcc() which is written in C - Replace KVM fastops with C-based stubs which avoids problems with the fastop infra related to latter not adhering to the C ABI due to their special calling convention and, more importantly, bypassing compiler control-flow integrity checking because they're written in asm - Remove wrongly used static branches and other ugliness accumulated over time in hyperv's hypercall implementation with a proper static function call to the correct hypervisor call variant - Add some fixes and modifications to allow running FRED-enabled kernels in KVM even on non-FRED hardware - Add kCFI improvements like validating indirect calls and prepare for enabling kCFI with GCC.
