x86: merge getuser asm functions.

2008-07-09T07:14:05Z

getuser_32.S and getuser_64.S are merged into getuser.S. Signed-off-by: Glauber Costa Signed-off-by: H. Peter Anvin Signed-off-by: Ingo Molnar

x86: use _ASM_PTR instead of explicit word-size pointers.

2008-07-09T07:14:04Z

Switch .long and .quad with _ASM_PTR in getuser*.S. Signed-off-by: Glauber Costa Signed-off-by: H. Peter Anvin Signed-off-by: Ingo Molnar

x86: introduce __ASM_REG macro.

2008-07-09T07:14:04Z

There are situations in which the architecture wants to use the register that represents its word-size, whatever it is. For those, introduce __ASM_REG in asm.h, along with the first users _ASM_AX and _ASM_DX. They have users waiting for it, namely the getuser functions. Signed-off-by: Glauber Costa Signed-off-by: H. Peter Anvin Signed-off-by: Ingo Molnar

x86: don't use word-size specifiers on getuser_64.

2008-07-09T07:14:03Z

The instructions access registers, so the size is unambiguous. Signed-off-by: Glauber Costa Signed-off-by: H. Peter Anvin Signed-off-by: Ingo Molnar

x86: rename threadinfo to TI.

2008-07-09T07:14:02Z

This is for consistency with i386. Signed-off-by: Glauber Costa Signed-off-by: H. Peter Anvin Signed-off-by: Ingo Molnar

x86: adapt x86_64 getuser functions.

2008-07-09T07:14:01Z

Instead of doing a sub after the addition, use the offset directly at the memory operand of the mov instructions. This is the way i386 do. Signed-off-by: Glauber Costa Signed-off-by: H. Peter Anvin Signed-off-by: Ingo Molnar

x86: don't clobber r8 nor use rcx.

2008-07-09T07:13:59Z

There's really no reason to clobber r8 or pass the address in rcx. We can safely use only two registers (which we already have to touch anyway) to do the job. Signed-off-by: Glauber Costa Signed-off-by: H. Peter Anvin Signed-off-by: Ingo Molnar

x86_64: move lib
