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

2008-01-30T12:32:27+00:00

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.

x86: move patching code to arch-specific file.

2008-01-30T12:32:10+00:00

The core patching code for paravirt is sufficiently different
among i386 and x86_64, and we move them to specific files.

x86: change paravirt_32.c name

2008-01-30T12:32:04+00:00

This patch changes paravirt_32.c to paravirt.c. The goal
is to have paravirt support in x86_64, so we do it in a common file

x86: i387 renaming

2008-01-30T12:31:50+00:00

This renames arch/x86/kernel/{i387_32.c => i387.c}.
This is a pure renaming, but paves the way for merging
the 32-bit and 64-bit versions of this code.

x86: kprobes code for x86 unification

2008-01-30T12:31:21+00:00

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.

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

x86: ptrace_32 renamed

2008-01-30T12:31:01+00:00

This renames ptrace_32.c back to ptrace.c, in preparation
for merging the 32/64 versions of these files.

x86: single_step: share code

2008-01-30T12:30:50+00:00

This removes the single-step code from ptrace_32.c and uses the step.c code
shared with the 64-bit kernel.  The two versions of the code were nearly
identical already, so the shared code has only a couple of simple #ifdef's.

x86: TLS cleanup

2008-01-30T12:30:46+00:00

This consolidates the four different places that implemented the same
encoding magic for the GDT-slot 32-bit TLS support.  The old tls32.c was
renamed and is now only slightly modified to be the shared implementation.
