x86: unify arch/x86/kernel/Makefile(s)

2008-01-30T12:32:27Z

Combine the 32 and 64 bit specific Makefiles in one file. While doing so link order was (almost) preserved on 32 bit but on 64 bit link order changed a lot. Patch was checked with defconfig + allyesconfig builds. The same .o files were linked in these configurations. To keep readability of the Makefiles a few Kconfig symbols was added/modified and it was checked that they were not used anywhere else. Signed-off-by: Sam Ravnborg Cc: "H.

x86: patching functions on 64-bit

2008-01-30T12:32:10Z

Like i386, x86_64 also need to include its own patching function. (Well, if you're not in a hurry, and don't care about speed, you don't really _need_ ;-)) So here they are. Not much different in essence from i386 Signed-off-by: Glauber de Oliveira Costa Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner

x86: x86 i387 user_regset

2008-01-30T12:31:50Z

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 what took the least cleanup in each file. Here i387.h is stubbed to always include i387_64.h rather than renaming the file, to keep this diff smaller and easier to read.

x86: kprobes code for x86 unification

2008-01-30T12:31:21Z

This patch unifies kprobes code. - Unify kprobes_*.h to kprobes.h - Unify kprobes_*.c to kprobes.c (Differences are separated by ifdefs) - Most differences are related to REX prefix and rip relatives. - Two inline assembly code are different. - One difference in kprobe_handlre() - One fixup exception code is different, but it will be unified if mm/extable_*.c are unified. - Merge history logs into arch/x86/kernel/kprobes.c.

x86: EFI runtime service support

2008-01-30T12:31:19Z

This patch adds basic runtime services support for EFI x86_64 system. The main file of the patch is the addition of efi_64.c for x86_64. This file is modeled after the EFI IA32 avatar. EFI runtime services initialization are implemented in efi_64.c. Some x86_64 specifics are worth noting here. On x86_64, parameters passed to EFI firmware services need to follow the EFI calling convention. For this purpose, a set of functions named efi_call ( is the number of parameters) are implemented. EFI function calls are wrapped before calling the firmware service. The duplicated code between efi_32.c and efi_64.c is placed in efi.c to remove them from efi_32.c.

x86, ptrace: support for branch trace store(BTS)

2008-01-30T12:31:09Z

Resend using different mail client Changes to the last version: - split implementation into two layers: ds/bts and ptrace - renamed TIF's - save/restore ds save area msr in __switch_to_xtra() - make block-stepping only look at BTF bit Signed-off-by: Markus Metzger Signed-off-by: Suresh Siddha Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner

x86: wipe out traditional opt from x86_64 Makefile

2008-01-30T12:31:03Z

Among other things, using -traditional as a gcc option stops us from using macro token pasting, which is a feature we heavily rely on. There was still a use of -traditional in arch/x86/kernel/Makefile_64, which this patch removes. I don't see any problems building kernels in my x86_64 box without -traditional.

x86: x86 ptrace merge complete

2008-01-30T12:31:02Z

This switches over the 64-bit build to use the shared ptrace code, instead of the old ptrace_64.c and arch/x86/ia32/ptrace32.c code. Signed-off-by: Roland McGrath Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner

x86: single_step moved

2008-01-30T12:30:50Z

This moves the single-step support code from ptrace_64.c into a new file step.c, verbatim. This paves the way for consolidating this code between 64-bit and 32-bit versions. Signed-off-by: Roland McGrath Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner

x86: tls32 moved

2008-01-30T12:30:45Z

This renames arch/x86/ia32/tls32.c to arch/x86/kernel/tls.c, which does nothing now but paves the way to consolidate this code for 32-bit too. Signed-off-by: Roland McGrath Cc: Andrew Morton Cc: Zachary Amsden Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner
