Anup Patel d5fdade933 RISC-V: mm: Fix set_satp_mode() for platform not having Sv57 ... When Sv57 is not available the satp.MODE test in set_satp_mode() will fail and lead to pgdir re-programming for Sv48. The pgdir re-programming will fail as well due to pre-existing pgdir entry used for Sv57 and as a result kernel fails to boot on RISC-V platform not having Sv57. To fix above issue, we should clear the pgdir memory in set_satp_mode() before re-programming.
