Subject: x86/kernel: Use kstack_end() in dumpstack_64.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=04769ae3ac72f86324a189b69f53bf3bfb61acfd;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

x86/kernel: Use kstack_end() in dumpstack_64.c

i386 is already using kstack_end() in dumpstack_32.c. We should also
use it to make the code clearer and unify the stack printing logic some
more.
