Subject: [PATCH] Update sysrq-B to use emergency_restart()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4de8b9b76017365572f778332d74fe050d9c8c2a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] Update sysrq-B to use emergency_restart()

sysrq calls into the reboot path from an interrupt handler
we can either push the code do into process context and
call kernel_restart and get a clean reboot or we can simply
reboot the machine, and increase our chances of actually
rebooting.  emergency_reboot() seems like the closest match
to what we have previously done, and what we want.
