From cc6978528cbd475d952e0eb5073375839dfb600e Mon Sep 17 00:00:00 2001 From: Glauber de Oliveira Costa Date: Wed, 30 Jan 2008 13:31:14 +0100 Subject: x86: modify get_desc_base This patch makes get_desc_base() receive a struct desc_struct, and then uses its internal fields to compute the base address. This is done at both i386 and x86_64, and then it is moved to common header Signed-off-by: Glauber de Oliveira Costa Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner --- include/asm-x86/desc.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'include/asm-x86/desc.h') diff --git a/include/asm-x86/desc.h b/include/asm-x86/desc.h index 99c4adc851e..a6fdd7c7b6b 100644 --- a/include/asm-x86/desc.h +++ b/include/asm-x86/desc.h @@ -69,6 +69,11 @@ static inline void load_LDT(mm_context_t *pc) preempt_enable(); } +static inline unsigned long get_desc_base(struct desc_struct *desc) +{ + return desc->base0 | ((desc->base1) << 16) | ((desc->base2) << 24); +} + #else /* * GET_DESC_BASE reads the descriptor base of the specified segment. -- cgit v1.2.3-70-g09d2
