2006-09-27[MIPS] Retire flush_icache_page from mm use.Ralf Baechle1-2/+5
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.

2006-09-13[PATCH] headers_check: fix userspace build of asm-mips/page.hDavid Woodhouse1-6/+2
MIPS asm/page.h unconditionally includes <asm-generic/memory_model.h>, 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.

2006-07-13[MIPS] Sparsemem fixesAtsushi Nemoto1-8/+4
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 <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* 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 <sys/types.h> to headers included for userspace in <linux/input.h> Move inclusion of <linux/compat.h> out of user scope in asm-x86_64/mtrr.h Remove struct fddi_statistics from user view in <linux/if_fddi.h> 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 <linux/types.h> and use __uXX types in <linux/cramfs_fs.h> Use __uXX types in <linux/i2o_dev.h>, include <linux/ioctl.h> too Remove private struct dx_hash_info from public view in <linux/ext3_fs.h> Include <linux/types.h> and use __uXX types in <linux/affs_hardblocks.h> Use __uXX types in <linux/divert.h> for struct divert_blk et al. Use __u32 for elf_addr_t in <asm-powerpc/elf.h>, not u32. It's user-visible. Remove PPP_FCS from user view in <linux/ppp_defs.h>, remove __P mess entirely Use __uXX types in user-visible structures in <linux/nbd.h> 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 <linux/time.h> from <linux/ufs_fs.h> Fix private integer types used in V4L2 ioctls. ... Manually resolve conflict in include/linux/mtd/physmap.h

2006-06-06[MIPS] Fix sparsemem support.Chad Reese1-0/+2
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.

2005-09-05[PATCH] mm: consolidate get_orderStephen Rothwell1-14/+2
Someone mentioned that almost all the architectures used basically the same implementation of get_order. This patch consolidates them into asm-generic/page.h and includes that in the appropriate places. The exceptions are ia64 and ppc which have their own (presumably optimised) versions.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+151
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!
