x86: re-add rdmsrl_safe

2008-04-17T15:41:30+00:00

RDMSR for 64bit values with exception handling.

Makes it easier to deal with 64bit valued MSRs. The old 64bit code
base had that too as checking_rdmsrl(), but it got dropped somehow.

x86: use _ASM_EXTABLE macro in include/asm-x86/msr.h

2008-02-04T15:47:58+00:00

Use the _ASM_EXTABLE macro from , instead of open-coding
__ex_table entires in include/asm-x86/msr.h.

x86: cleanup write_tsc

2008-01-30T12:32:05+00:00

write_tsc() does not need to be enclosed in any paravirt closure,
as it uses wrmsr(). So we rip off the duplicate in msr.h
and the definition from paravirt.h

x86: integrate 32-bit and 64-bit code in msr.h

2008-01-30T12:31:07+00:00

This patches proceeds with the integration of msr.h, making
the code unified, instead of having a version for each architecture.
We stick with the native_* functions, and then paravirt comes for free.

x86: make fixups wordsize agnostic

2008-01-30T12:31:07+00:00

This patch uses the _ASM_ALIGN and _ASM_PTR macros
to make the fixups in native_read/write_msr_safe look the same
for x86_64 and i386. Besides using this macros, we also have to
take the explicit instruction suffixes out. It's okay
because all this instructions uses registers, and can be sized by
them.

x86: change write msr functions interface

2008-01-30T12:31:07+00:00

This patche changes the native_write_msr() and friends interface
to explicitly take 2 32-bit registers instead of a 64-bit value.
The change will ease the merge with 64-bit code. As the 64-bit
value will be passed as two registers anyway in i386,
the PVOP_CALL interface has to account for that and use low/high parameters
It would force the x86_64 version to be different.

The change does not make i386 generated code less efficient. As said above,
it would get the values from two registers anyway.
