From 546953c0c553465761705fb0747964c08d634461 Mon Sep 17 00:00:00 2001

Subject: Replace hlt with halt()

There were instances of unneeded arch/hlt.h includes,
various hlt() calls that weren't supposed to exit (but
might have) and various forms of endless loops around
hlt() calls.

All these are sorted out now: unnecessary includes are
dropped, hlt() is uniformly replaced with halt() (except
in assembly, obviously).
