asm-compat.h	powerpc: move ASM_CONST and stringify_in_c() into asm-const.h This patch moves ASM_CONST() and stringify_in_c() into dedicated asm-const.h, then cleans all related inclusions. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> [mpe: asm-compat.h should include asm-const.h] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>	7 年前
export.h	seltests/powerpc: Add a selftest for memcpy_mcsafe Appropriate self tests for memcpy_mcsafe Suggested-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Santosh Sivaraj <santosh@fossix.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20190903214359.23887-2-santosh@fossix.org	6 年前
feature-fixups.h	powerpc: clean inclusions of asm/feature-fixups.h files not using feature fixup don't need asm/feature-fixups.h files using feature fixup need asm/feature-fixups.h Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>	7 年前
kasan.h	powerpc: prepare string/mem functions for KASAN CONFIG_KASAN implements wrappers for memcpy() memmove() and memset() Those wrappers are doing the verification then call respectively __memcpy() __memmove() and __memset(). The arches are therefore expected to rename their optimised functions that way. For files on which KASAN is inhibited, #defines are used to allow them to directly call optimised versions of the functions without going through the KASAN wrappers. See commit 393f203f5fd5 ("x86_64: kasan: add interceptors for memset/memmove/memcpy functions") for details. Other string / mem functions do not (yet) have kasan wrappers, we therefore have to fallback to the generic versions when KASAN is active, otherwise KASAN checks will be skipped.

processor.h	selftests/powerpc: Import Anton's memcpy / copy_tofrom_user tests Turn Anton's memcpy / copy_tofrom_user test into something that can live in tools/testing/selftests. It requires one turd in arch/powerpc/lib/memcpy_64.S, but it's pretty harmless IMHO. We are sailing very close to the wind with the feature macros. We define them to nothing, which currently means we get a few extra nops and include the unaligned calls.
