See: https://lore.kernel.org/qemu-devel/cover.1726293808.git.mchehab+huawei@kernel.org/ Such change ended being a big patch, so several intermediate steps are needed, together with several cleanups and renames. As agreed duing v10 review, I'll be splitting the big patch series into separate pull requests, starting with the cleanup series. This is the first patch set, containing only such preparation patches. The next series will contain the shift to use offsets from the location of the HEST table, together with a migration logic to make it compatible with 9.1. --- v4: - merged a patch renaming the function which calculate offsets to: get_hw_error_offsets(), to avoid the need of such change at the next patch series; - removed a functional change at the logic which makes the GHES record generation more generic; - a couple of trivial changes on patch descriptions and line break cleanups. v3: - improved some patch descriptions; - some patches got reordered to better reflect the changes; - patch v2 08/15: acpi/ghes: Prepare to support multiple sources on ghes was split on two patches. The first one is in this cleanup series: acpi/ghes: Change ghes fill logic to work with only one source contains just the simplification logic. The actual preparation will be moved to this series: https://lore.kernel.org/qemu-devel/cover.1727782588.git.mchehab+huawei@kernel.org/ v2: - some indentation fixes; - some description improvements; - fixed a badly-solved merge conflict that ended renaming a parameter.
