It fixes an earlyprintk=efi regression introduced in v3.16. Due to changes in the early ACPI code we run out of early_ioremap slots when earlyprintk=efi is specified on the command line, resulting in a hang during kernel boot. This patch is clearly a core x86 change, but since it is a fix for an EFI code issue I picked it up in my urgent queue. Let me know if you'd like to route this some other way. The following changes since commit 0ceac9e094b065fe3fec19669740f338d3480498: efi/arm64: Fix fdt-related memory reservation (2014-09-09 07:51:09 +0100) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi.git tags/efi-urgent for you to fetch changes up to 3eddc69ffeba092d288c386646bfa5ec0fce25fd: x86 early_ioremap: Increase FIX_BTMAPS_SLOTS to 8 (2014-09-14 15:24:31 +0100) ---------------------------------------------------------------- * Increase the number of early_ioremap slots to fix a regression with earlyprintk=efi after recent changes to the ACPI code - Dave Young ---------------------------------------------------------------- Dave Young (1): x86 early_ioremap: Increase FIX_BTMAPS_SLOTS to 8 arch/x86/include/asm/fixmap.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) -- Matt Fleming, Intel Open Source Technology Center
