From: Matteo Croce <mcroce@microsoft.com>

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.

Matteo Croce (2):
reboot: fix overflow parsing reboot cpu number
reboot: fix parsing of reboot cpu number
