This matches other prints like those for SRAT and nosave memory. Change the closing ) to ] to match the opening [. old: efi: mem61: [Persistent Memory | | | | | | | |WB|WT|WC|UC] range=[0x0000000880000000-0x0000000c80000000) (16384MB) new: efi: mem61: [Persistent Memory | | | | | | | |WB|WT|WC|UC] range=[0x0000000880000000-0x0000000c7fffffff] (16384MB) Example other address range prints: SRAT: Node 1 PXM 1 [mem 0x480000000-0x87fffffff] PM: Registered nosave memory: [mem 0x880000000-0xc7fffffff] Signed-off-by: Robert Elliott --- arch/x86/platform/efi/efi.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/x86/platform/efi/efi.c b/arch/x86/platform/efi/efi.c index ad28540..635a955 100644 --- a/arch/x86/platform/efi/efi.c +++ b/arch/x86/platform/efi/efi.c @@ -235,10 +235,10 @@ void __init efi_print_memmap(void) char buf[64]; md = p; - pr_info("mem%02u: %s range=[0x%016llx-0x%016llx) (%lluMB)\n", + pr_info("mem%02u: %s range=[0x%016llx-0x%016llx] (%lluMB)\n", i, efi_md_typeattr_format(buf, sizeof(buf), md), md->phys_addr, - md->phys_addr + (md->num_pages << EFI_PAGE_SHIFT), + md->phys_addr + (md->num_pages << EFI_PAGE_SHIFT) - 1, (md->num_pages >> (20 - EFI_PAGE_SHIFT))); } #endif /* EFI_DEBUG */ -- 2.4.3
