2008-07-09x86: use _ASM_PTR instead of explicit word-size pointers.Glauber Costa

2008-07-09x86: introduce __ASM_REG macro.Glauber Costa
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.

2008-07-09x86: don't use word-size specifiers on getuser_64.Glauber Costa
The instructions access registers, so the size is unambiguous. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-07-09x86: rename threadinfo to TI.Glauber Costa
This is for consistency with i386. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-07-09x86: adapt x86_64 getuser functions.Glauber Costa
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 <gcosta@redhat.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-07-09x86: don't clobber r8 nor use rcx.Glauber Costa
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 <gcosta@redhat.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
