Subject: [PATCH v5 0/2] x86/boot: Warn on future overlapping memcpy() use
Date: Mon,  2 May 2016 15:50:59 -0700

This attempts to bring some sanity to how warn() and error() are defined
so that they can be used by misc.c, kaslr.c, and string.c. After that,
we add a warn() to memcpy and call memmove on detected overlaps.

-Kees

v5:
- split out warn/error into error.c/error.h
v4:
- use __memcpy not memcpy since we've already done the check.
v3:
- call memmove in addition to doing the warning
v2:
- warn about overlapping region
