The previous try at: https://lore.kernel.org/r/20220304035110.988712-1-helgaas@kernel.org caused regressions on some Chromebooks: https://lore.kernel.org/r/Yjyv03JsetIsTJxN@sirena.org.uk This v2 drops the commit that caused the Chromebook regression, so it also doesn't fix the issue we were *trying* to fix on Lenovo Yoga and Clevo Barebones. The point of this v2 update is to split the logging patch into (1) a pure logging addition and (2) the change to only clip PCI windows, which was previously hidden inside the logging patch and not well documented. Bjorn Helgaas (3): x86/PCI: Eliminate remove_e820_regions() common subexpressions x86: Log resource clipping for E820 regions x86/PCI: Clip only host bridge windows for E820 regions arch/x86/include/asm/e820/api.h | 5 +++++ arch/x86/kernel/resource.c | 23 ++++++++++++++++------- arch/x86/pci/acpi.c | 5 +++++ 3 files changed, 26 insertions(+), 7 deletions(-) -- 2.25.1
