[MIPS] Retire flush_icache_page from mm use.

2006-09-27T12:37:34Z

On the 34K the redundant cache operations were causing excessive stalls resulting in realtime code running on the second VPE missing its deadline. For all other platforms this patch is just a significant performance improvment as illustrated by below benchmark numbers.

[PATCH] headers_check: fix userspace build of asm-mips/page.h

2006-09-13T14:32:16Z

MIPS asm/page.h unconditionally includes , which doesn't exist in userspace. Move an #endif /* __KERNEL__ */ down a few lines to prevent that. Also, remove the broken definition of PAGE_SIZE which is never going to be correct -- in the absence of PAGE_SIZE, non-broken userspace will fall back to using sysconf() or getpagesize() instead.

[MIPS] Sparsemem fixes

2006-07-13T20:26:07Z

1. MIPS should select SPARSEMEM_STATIC since allocating bootmem in memory_present() will corrupt bootmap area. 2. pfn_valid() for SPARSEMEM is defined in linux/mmzone.h Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle

* git://git.infradead.org/hdrcleanup-2.6: (63 commits) [S390] __FD_foo definitions. Switch to __s32 types in joystick.h instead of C99 types for consistency. Add to headers included for userspace in Move inclusion of out of user scope in asm-x86_64/mtrr.h Remove struct fddi_statistics from user view in Move user-visible parts of drivers/s390/crypto/z90crypt.h to include/asm-s390 Revert include/media changes: Mauro says those ioctls are only used in-kernel(!) Include and use __uXX types in Use __uXX types in , include too Remove private struct dx_hash_info from public view in Include and use __uXX types in Use __uXX types in for struct divert_blk et al. Use __u32 for elf_addr_t in , not u32. It's user-visible. Remove PPP_FCS from user view in , remove __P mess entirely Use __uXX types in user-visible structures in Don't use 'u32' in user-visible struct ip_conntrack_old_tuple. Use __uXX types for S390 DASD volume label definitions which are user-visible S390 BIODASDREADCMB ioctl should use __u64 not u64 type. Remove unneeded inclusion of from Fix private integer types used in V4L2 ioctls. ... Manually resolve conflict in include/linux/mtd/physmap.h

[MIPS] Fix sparsemem support.

2006-06-05T23:15:20Z

Move memory_present() in arch/mips/kernel/setup.c. When using sparsemem extreme, this function does an allocate for bootmem. This would always fail since init_bootmem hasn't been called yet. Move memory_present after free_bootmem. This only marks actual memory ranges as present instead of the entire address space. Signed-off-by: Chad Reese Signed-off-by: Ralf Baechle
