Shanker Donthineni ea6eac904f arm64: Avoid clobbering mm in erratum workaround on QDF2400 ... Commit 38fd94b027 ("arm64: Work around Falkor erratum 1003") tried to work around a hardware erratum, but actually caused a system crash of its own during switch_mm: cpu_do_switch_mm+0x20/0x40 efi_virtmap_load+0x34/0x40 virt_efi_get_next_variable+0x64/0xc8 efivar_init+0x8c/0x348 efisubsys_init+0xd4/0x270 do_one_initcall+0x80/0x110 kernel_init_freeable+0x19c/0x240 kernel_init+0x10/0x100 ret_from_fork+0x10/0x50 Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b In cpu_do_switch_mm, x1 contains the mm_struct pointer, which needs to be preserved by the pre_ttbr0_update_workaround macro rather than passed as a temporary. This patch clobbers x2 and x3 instead, keeping the mm_struct intact after the workaround has run.
