From 26d7f65fbd22168c33d2350f3e7e3021f5761256 Mon Sep 17 00:00:00 2001 From: Matt Fleming Date: Sun, 25 Oct 2015 10:26:35 +0000 Subject: x86/efi: Preface all print statements with efi* tag The pr_*() calls in the x86 EFI code may or may not include a subsystem tag, which makes it difficult to grep the kernel log for all relevant EFI messages and leads users to miss important information. Recently, a bug reporter provided all the EFI print messages from the kernel log when trying to diagnose an issue but missed the following statement because it wasn't prefixed with anything indicating it was related to EFI, pr_err("Error ident-mapping new memmap (0x%lx)!\n", pa_memmap); Cc: Borislav Petkov Reviewed-by: Josh Triplett Signed-off-by: Matt Fleming --- arch/x86/platform/efi/quirks.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'arch/x86/platform/efi/quirks.c') diff --git a/arch/x86/platform/efi/quirks.c b/arch/x86/platform/efi/quirks.c index 1c7380da65ff..6452070f3025 100644 --- a/arch/x86/platform/efi/quirks.c +++ b/arch/x86/platform/efi/quirks.c @@ -1,3 +1,5 @@ +#define pr_fmt(fmt) "efi: " fmt + #include #include #include @@ -256,7 +258,7 @@ void __init efi_apply_memmap_quirks(void) * services. */ if (!efi_runtime_supported()) { - pr_info("efi: Setup done, disabling due to 32/64-bit mismatch\n"); + pr_info("Setup done, disabling due to 32/64-bit mismatch\n"); efi_unmap_memmap(); } -- cgit v1.2.3
