X-Git-Tag: v6.15-rc1~113^2~22
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5864614daf4a3e5dfa434e0f2f84e6d8cfe4126d;p=thirdparty%2Fkernel%2Flinux.git

s390/traps: Use pr_emerg() instead of printk()

Use pr_emerg() instead of printk() in case of a stack overflow,
providing the emergency printk level. Also slightly adjust the
printed text for pr_emerg() and panic().
