[PATCH] checkpoint: remove unbuildable compat code

[PATCH] checkpoint: remove unbuildable compat code

[Nathan Lynch]

The code bracketed in CONFIG_COMPAT in checkpoint/process.c refers to
symbols that are static in kernel/compat.c (compat_nanosleep_restart,
compat_clock_nanosleep_restart).  This causes builds with
CONFIG_COMPAT=y to fail.

Just remove the offending code, it seems unlikely to have been tested.
