PATCH: Fix SVM MSR indexes for 32bit kernel

["H. J. Lu" <hjl@lucon.org>]

Hi,

MSR index is 32bit not 64bit. All other MSR indexes are defined
without the ULL suffix. Otherwise, you will get

[hjl@gnu-5 tmp]$ cat foo.c
typedef unsigned long long u64;

int is_disabled(void)
{
 u64 vm_cr;

 do { unsigned long l__,h__; __asm__ __volatile__("rdmsr" : "=a" (l__),
"=d" (h__) : "c" (0xc0010114ULL)); vm_cr = l__; vm_cr |=
((u64)h__<<32); } while(0);
 if (vm_cr & (1 << 4))
  return 1;

 return 0;
}
[hjl@gnu-5 tmp]$ gcc -m32 -S foo.c
foo.c: In function â_disabledâfoo.c:7: error: impossible register
constraint in âmâoo.c:12: confused by earlier errors, bailing out
[hjl@gnu-5 tmp]$

on 32bit. This patch removes the ULL suffix in SVM MSR indexes.
