[PATCH -mm 31/43] x86 i387 user_regset

2007-12-20 Thread Roland McGrath
This revamps the i387 code to be shared across 32-bit, 64-bit, and 32-on-64. It does so by consolidating the code in one place based on the user_regset accessor interfaces. This switches 32-bit to using the i387_64.h header and 64-bit to using the i387.c that was previously i387_32.c, but that's

[PATCH -mm 27/43] x86 i387 unify structs

2007-12-20 Thread Roland McGrath
The i387_fxsave_struct formats really have the same layout on 32 and 64, with only some slightly different use of a few fields. The i387_fsave_struct and i387_soft_struct formats are never used by 64-bit kernels, but it doesn't hurt to have the unused types in the union and cuts down on the

2007-12-20 Thread Roland McGrath
This converts the ptrace/signal accessors for i387 math_emu state to the user_regset interface style, and calls these from the old interfaces. It also cleans up math_emulate's ptrace check to be a single-step check, which is what it really wants. Signed-off-by: Roland McGrath [EMAIL PROTECTED]

This provides the task_user_regset_view entry point and support for all the native-mode (64 on CONFIG_PPC64, 32 on CONFIG_PPC32) thread register state. This will enable generic machine-independent code to access user-mode threads' registers for debugging and dumping. Signed-off-by: Roland McGrath

2007-12-20 Thread Roland McGrath
This switches the CONFIG_PPC64 support for 32-bit ELF to use the generic fs/compat_binfmt_elf.c implementation instead of our own binfmt_elf32.c. Since so much is the same between 32/64, there is only one macro we have to define to make the generic support work out of the box. Signed-off-by:

This moves some code into asm-x86/i387_64.h in preparation for unifying this code between 32 and 64. The 32-bit versions of some things are copied in some existing names changed to match 32-bit names and share code. For 64, save_i387 is moved into an inline from i387_64.c; this matches
