How about trace_signal_deliver(SIGKILL, SEND_SIG_NOINFO, &sighand->action[signr - 1]); ? Although we know that action[SIGKILL] must be SIG_DFL, in order to adapt to the parameter type, I suggest to use the original variable value. Zhenliang Wei.

[PATCH] arm64: mm: Ensure tail of unaligned initrd is reserved

by Bjorn Andersson

In the event that the start address of the initrd is not aligned, but has an aligned size, the base + size will not cover the entire initrd image and there is a chance that the kernel will corrupt the tail of the image. By aligning the end of the initrd to a page boundary and then subtracting the adjusted start address the memblock reservation will cover all pages that contains the initrd.
