Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

Revert "MIPS: Don't unnecessarily include kmalloc.h into <asm/cache.h>." Commit 296e46db0073 ("MIPS: Don't unnecessarily include kmalloc.h into <asm/cache.h>.") 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 <asm/cache.h>.")

treewide: Convert macro and uses of __section(foo) to __section("foo") 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 <joe@perches.com> Reviewed-by: Nick Desaulniers <ndesaulniers@gooogle.com> Reviewed-by: Miguel Ojeda <ojeda@kernel.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

MIPS: Implement __read_mostly 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.

mips: move cache declarations into header Some of the cache functions are declared only for their callers, e.g. arch/mips/mm/c-r3k.c:28:15: error: no previous prototype for 'r3k_cache_size' [-Werror=missing-prototypes] arch/mips/mm/c-r3k.c:63:15: error: no previous prototype for 'r3k_cache_lsize' [-Werror=missing-prototypes] arch/mips/mm/c-r4k.c:1703:6: error: no previous prototype for 'r4k_cache_init' [-Werror=missing-prototypes] arch/mips/mm/sc-mips.c:255:5: error: no previous prototype for 'mips_sc_init' [-Werror=missing-prototypes] Move all the declarations to asm/cache.h and asm/r4kcache.h where they can be seen by the function definitions.
