Merge tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx

2020-04-03T20:12:26Z

Pull SPDX updates from Greg KH: "Here are three SPDX patches for 5.7-rc1. One fixes up the SPDX tag for a single driver, while the other two go through the tree and add SPDX tags for all of the .gitignore files as needed. Nothing too complex, but you will get a merge conflict with your current tree, that should be trivial to handle (one file modified by two things, one file deleted.) All three of these have been in linux-next for a while, with no reported issues other than the merge conflict" * tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx: ASoC: MT6660: make spdxcheck.py happy .gitignore: add SPDX License Identifier .gitignore: remove too obvious comments

x86/boot/compressed: Fix debug_puthex() parameter type

2020-03-28T11:14:26Z

In the CONFIG_X86_VERBOSE_BOOTUP=Y case, the debug_puthex() macro just turns into __puthex(), which takes 'unsigned long' as parameter. But in the CONFIG_X86_VERBOSE_BOOTUP=N case, it is a function which takes 'unsigned char *', causing compile warnings when the function is used. Fix the parameter type to get rid of the warnings.

efi/x86: Don't relocate the kernel unless necessary

2020-03-08T08:58:22Z

Add alignment slack to the PE image size, so that we can realign the decompression buffer within the space allocated for the image. Only relocate the kernel if it has been loaded at an unsuitable address: - Below LOAD_PHYSICAL_ADDR, or - Above 64T for 64-bit and 512MiB for 32-bit For 32-bit, the upper limit is conservative, but the exact limit can be difficult to calculate.

efi/x86: Remove extra headroom for setup block

2020-03-08T08:58:21Z

The following commit: 223e3ee56f77 ("efi/x86: add headroom to decompressor BSS to account for setup block") added headroom to the PE image to account for the setup block, which wasn't used for the decompression buffer. Now that the decompression buffer is located at the start of the image, and includes the setup block, this is no longer required. Add a check to make sure that the head section of the compressed kernel won't overwrite itself while relocating. This is only for future-proofing as with current limits on the setup and the actual size of the head section, this can never happen.

efi/x86: Add kernel preferred address to PE header

2020-03-08T08:58:20Z

Store the kernel's link address as ImageBase in the PE header. Note that the PE specification requires the ImageBase to be 64k aligned. The preferred address should almost always satisfy that, except for 32-bit kernel if the configuration has been customized.

efi/x86: Decompress at start of PE image load address

2020-03-08T08:58:19Z

When booted via PE loader, define image_offset to hold the offset of startup_32() from the start of the PE image, and use it as the start of the decompression buffer.
