2017-08-07	Revert "MIPS: Don't unnecessarily include kmalloc.h into <asm/cache.h>."	Paul Burton	1	-0/+2
	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>.")

2017-04-10	MIPS: Delete redundant definition of SMP_CACHE_BYTES.	Ralf Baechle	1	-2/+0
	<linux/cache.h> already defines SMP_CACHE_BYTES as L1_CACHE_BYTES. This change results in a build error in <asm/cpu-info.h> which directly includes <asm/cache.h>. Fix this by including <linux/cache.h> instead. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2011-01-18	MIPS: Implement __read_mostly	David Daney	1	-0/+2
	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.
