This is a continuation of Hans's work [0] to ignore bogus romimage/romsize values in the EFI PCI I/O protocol instances exposed by some UEFI firmwares on x86. I have only build tested this, both on 32 and 64 bit x86. Changes in v4: - Deduplicate the 32 and 64 bit code paths so that the actual change needs to be applied only once. This requires some preparatory work (#1, #2, #3), of which the first one should go to -stable. Changes in v3: - Limit the rom-size to 16MiB to match the EFI spec Changes in v2: - Add the check to both __setup_efi_pci32 and __setup_efi_pci64 instead of only to __setup_efi_pci64, some CHT devices which need this still use a 32 bit UEFI [0] https://marc.info/?l=linux-efi&m=152494632116321 Ard Biesheuvel (3): efi: fix efi_pci_io_protocol32 prototype for mixed mode efi: align efi_pci_io_protocol typedefs to type naming convention efi/x86: fold __setup_efi_pci32 and __setup_efi_pci64 into one Hans de Goede (1): efi/x86: Ignore unrealistically large option roms arch/x86/boot/compressed/eboot.c | 112 ++++++-------------- include/linux/efi.h | 14 +-- 2 files changed, 39 insertions(+), 87 deletions(-) -- 2.17.0 -- To unsubscribe from this list: send the line "unsubscribe linux-efi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
