Hi Everyone, This series improves acpi_os_execute() on top of https://patchwork.kernel.org/project/linux-acpi/patch/5745568.DvuYhMxLoT@kreacher/ but only the last patch really depends on it. The first two patches clean up the code somewhat and the third one modifies the function to allow Notify () handlers to run on all CPUs (not on CPU0 only). The last patch changes it to use GFP_KERNEL for memory allocations, as it does not run in interrupt context any more after the change linked above. Thanks!
