[PATCH]cleaning of the definition of HANDLE_STACK and related compilation warning

[Giangiacomo Mariotti]

This is my new version of a patch that I've already posted in kernel-janitors.
This new version cleans the definition of the macro HANDLE_STACK in
arch/x86_64/kernel/traps.c and erases a related compilation warning
about while(){} not being a compound statement.
