MIPS: Move declaration of bcache ops to cache.c

2023-04-05T07:45:08+00:00

bcache is not tied to CPU's cache interface. Just move those declaration to cache.c so it can be avaialble to CPU with all cache types. Signed-off-by: Jiaxun Yang Signed-off-by: Thomas Bogendoerfer

treewide: Convert macro and uses of section(foo) to section("foo")

2020-10-25T21:51:49+00:00

Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms. Conversion done using the script at: https://lore.kernel.org/lkml/75393e5ddc272dc7403de74d645e6c6e0f4e70eb.camel@perches.com/2-convert_section.pl Signed-off-by: Joe Perches Reviewed-by: Nick Desaulniers Reviewed-by: Miguel Ojeda Signed-off-by: Linus Torvalds

Revert "MIPS: Don't unnecessarily include kmalloc.h into ."

2017-08-07T10:01:17+00:00

Commit 296e46db0073 ("MIPS: Don't unnecessarily include kmalloc.h into .") claimed that the inclusion of the machine's kmalloc.h from asm/cache.h is unnecessary, but this is not true. Without including kmalloc.h we don't get a definition for ARCH_DMA_MINALIGN, which means we no longer suitably align DMA. Further to this the definition of ARCH_KMALLOC_MINALIGN provided by linux/slab.h ends up being set to the alignment of an unsigned long long value rather than to ARCH_DMA_MINALIGN, which means that buffers allocated using kmalloc may no longer be safely aligned for use with DMA. Fix this by re-adding the include of kmalloc.h in asm/cache.h. This reverts commit 296e46db0073 ("MIPS: Don't unnecessarily include kmalloc.h into .")

MIPS: Delete redundant definition of SMP_CACHE_BYTES.

MIPS: Implement __read_mostly

2011-01-18T18:30:28+00:00

Just do what everyone else is doing by placing __read_mostly things in the .data.read_mostly section. mips_io_port_base can not be read-only (const) and writable (__read_mostly) at the same time. One of them has to go, so I chose to eliminate the __read_mostly. It will still get stuck in a portion of memory that is not adjacent to things that are written, and thus not be on a dirty cache line, for whatever that is worth.
