* [MIPS] Fix missing prototypes in asm/fpu.hDmitri Vorobiev2008-07-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | While building the Malta defconfig, sparse spat the following warnings: >>>>>>>>>>>>>>>>>> arch/mips/math-emu/kernel_linkage.c:31:6: warning: symbol 'fpu_emulator_init_fpu' was not declared. Should it be static? arch/mips/math-emu/kernel_linkage.c:54:5: warning: symbol 'fpu_emulator_save_context' was not declared. Should it be static? arch/mips/math-emu/kernel_linkage.c:68:5: warning: symbol 'fpu_emulator_restore_context' was not declared. Should it be static? >>>>>>>>>>>>>>>>>> This patch fixes these errors by adding the proper prototypes to the include/asm-mips/fpu.h header, and actually using this header in the sparse-spotted source file.

| | | | | | | | | | | | | remove asm/bitops.h includes including asm/bitops directly may cause compile errors. don't include it and include linux/bitops instead. next patch will deny including asm header directly.

* [MIPS] Retry {save,restore}_fp_context if failed in atomic context.Atsushi Nemoto2007-04-201-2/+7
| | | | | | | | | | | | | | | The save_fp_context()/restore_fp_context() might sleep on accessing user stack and therefore might lose FPU ownership in middle of them. If these function failed due to "in_atomic" test in do_page_fault, touch the sigcontext area in non-atomic context and retry these save/restore operation. This is a replacement of a (broken) fix which was titled "Allow CpU exception in kernel partially".

| | | | | | | | | The commit 4d40bff7110e9e1a97ff8c01bdd6350e9867cc10 ("Allow CpU exception in kernel partially") was broken. The commit was to fix theoretical problem but broke usual case.

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

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!
