x86: change assembly definition of paravirt_patch_site To account for differences in x86_64, we change the macros that create raw instances of the paravirt_patch_site struct. We need to align 64-pointers to 64-bit boundaries, so we add an alignment directive. Also, we need to make room for a word-sized pointer, instead of a fixed 32-bit one Signed-off-by: Glauber de Oliveira Costa <[EMAIL PROTECTED]> Signed-off-by: Ingo Molnar <[EMAIL PROTECTED]> Signed-off-by: Thomas Gleixner <[EMAIL PROTECTED]> --- include/asm-x86/paravirt.h | 16 +++++++++++++--- 1 files changed, 13 insertions(+), 3 deletions(-) diff --git a/include/asm-x86/paravirt.h b/include/asm-x86/paravirt.h index 8f79843..5638995 100644 --- a/include/asm-x86/paravirt.h +++ b/include/asm-x86/paravirt.h @@ -5,6 +5,7 @@ #ifdef CONFIG_PARAVIRT #include <asm/page.h> +#include <asm/asm.h> /* Bitmask of what can be clobbered: usually at least eax. */ #define CLBR_NONE 0x0 @@ -281,7 +282,8 @@ extern struct pv_mmu_ops pv_mmu_ops; #define _paravirt_alt(insn_string, type, clobber) \ "771:\n\t" insn_string "\n" "772:\n" \ ".pushsection .parainstructions,\"a\"\n" \ - " .long 771b\n" \ + _ASM_ALIGN "\n" \ + _ASM_PTR " 771b\n" \ " .byte " type "\n" \ " .byte 772b-771b\n" \ " .short " clobber "\n" \ @@ -1159,17 +1161,25 @@ static inline unsigned long __raw_local_irq_save(void) #define PARA_PATCH(struct, off) ((PARAVIRT_PATCH_##struct + (off)) / 4) -#define PARA_SITE(ptype, clobbers, ops) \ +#define _PVSITE(ptype, clobbers, ops, word, algn) \ 771:; \ ops; \ 772:; \ .pushsection .parainstructions,"a"; \ - .long 771b; \ + .align algn; \ + word 771b; \ .byte ptype; \ .byte 772b-771b; \ .short clobbers; \ .popsection + +#ifdef CONFIG_X86_64 +#define PARA_SITE(ptype, clobbers, ops) _PVSITE(ptype, clobbers, ops, .quad, 8) +#else +#define PARA_SITE(ptype, clobbers, ops) _PVSITE(ptype, clobbers, ops, .long, 4) +#endif + #define INTERRUPT_RETURN \ PARA_SITE(PARA_PATCH(pv_cpu_ops, PV_CPU_iret), CLBR_NONE, \ jmp *%cs:pv_cpu_ops+PV_CPU_iret) - To unsubscribe from this list: send the line "unsubscribe git-commits-head" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
