Subject: s390/dumpstack: use pr_cont within show_stack and die
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=47ece7fef4e4206cdcee7c28ac3bca3ede0a1908;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

s390/dumpstack: use pr_cont within show_stack and die

Use pr_cont instead of printk calls also within show_stack and
die in order to avoid extra line breaks.
