However, as it turns out, the vmap() call we ended up removing did not just map the header, but the entire capsule image, and dropping this virtual mapping breaks capsules that are processed by the firmware immediately (i.e., without a reboot). [FIX] The following patch fixes the issue https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/firmware/efi/capsule-loader.c?id=f24c4d478013d82bd1b943df566fff3561d52864 [TEST] Please see comments below for testing information and details. [REGRESSION POTENTIAL] This patch fixes a regression in 4.13 and onward.
