[PATCH v2 0/2] fix parsing of reboot= cmdline
From: Matteo Croce

From: Matteo Croce <mcroce@xxxxxxxxxxxxx>
The parsing of the reboot= cmdline has two major errors:
- a missing bound check can crash the system on reboot
- parsing of the cpu number only works if specified last
Fix both, along with a small code refactor.
v1->v2:
As Petr suggested, don't force base 10 in simple_strtoul(),
so hex values are accepted as well.

reboot: fix overflow parsing reboot cpu number
