It ended up being suboptimal in # various ways. # # This reworks the X86 irq stack handling: # # - Make the stack switching inline so the stackpointer manipulation is # not longer at an easy to find place. # # - Get rid of the unnecessary indirect call. # # - Avoid the double stack switching in interrupt return and reuse the # interrupt stack for softirq handling. # # - A objtool fix for CONFIG_FRAME_POINTER=y builds where it got # confused about the stack pointer manipulation" # # * tag 'x86-entry-2021-02-24' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # objtool: Fix stack-swizzle for FRAME_POINTER=y # um: Enforce the usage of asm-generic/softirq_stack.h #
