------------------ From: Dave Young <[email protected]> commit a7f84f03f660d93574ac88835d056c0d6468aebe upstream. Current code check boot service region with kernel text region by: start+size >= __pa_symbol(_text) The end of the above region should be start + size - 1 instead. I see this problem in ovmf + Fedora 19 grub boot: text start: 1000000 md start: 800000 md size: 800000 Signed-off-by: Dave Young <[email protected]> Acked-by: Borislav Petkov <[email protected]> Acked-by: Toshi Kani <[email protected]> Tested-by: Toshi Kani <[email protected]> Signed-off-by: Matt Fleming <[email protected]> [ kamal: backport to 3.8 (virt_to_phys instead of __pa_symbol) ] Signed-off-by: Kamal Mostafa <[email protected]> --- arch/x86/platform/efi/efi.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/x86/platform/efi/efi.c b/arch/x86/platform/efi/efi.c index 2a5d329..b826ce8 100644 --- a/arch/x86/platform/efi/efi.c +++ b/arch/x86/platform/efi/efi.c @@ -428,7 +428,7 @@ void __init efi_reserve_boot_services(void) * - Not within any part of the kernel * - Not the bios reserved area */ - if ((start+size >= virt_to_phys(_text) + if ((start + size > virt_to_phys(_text) && start <= virt_to_phys(_end)) || !e820_all_mapped(start, start+size, E820_RAM) || memblock_is_region_reserved(start, size)) { -- 1.8.3.2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
