From 8f12dea6135d0a55b151dcb4c6bbe211f5f8d35d Mon Sep 17 00:00:00 2001 From: Glauber de Oliveira Costa Date: Wed, 30 Jan 2008 13:31:06 +0100 Subject: x86: introduce native_read_tscp Targetting paravirt, this patch introduces native_read_tscp, in place of rdtscp() macro. When in a paravirt guest, this will involve a function call, and thus, cannot be done in the vdso area. These users then have to call the native version directly Signed-off-by: Glauber de Oliveira Costa Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner --- arch/x86/vdso/vgetcpu.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'arch/x86/vdso') diff --git a/arch/x86/vdso/vgetcpu.c b/arch/x86/vdso/vgetcpu.c index 3b1ae1abfba..c8097f17f8a 100644 --- a/arch/x86/vdso/vgetcpu.c +++ b/arch/x86/vdso/vgetcpu.c @@ -15,11 +15,11 @@ long __vdso_getcpu(unsigned *cpu, unsigned *node, struct getcpu_cache *unused) { - unsigned int dummy, p; + unsigned int p; if (*vdso_vgetcpu_mode == VGETCPU_RDTSCP) { /* Load per CPU data from RDTSCP */ - rdtscp(dummy, dummy, p); + native_read_tscp(&p); } else { /* Load per CPU data from GDT */ asm("lsl %1,%0" : "=r" (p) : "r" (__PER_CPU_SEG)); -- cgit v1.2.3
