History
Andreas Kling 5ce1cc89a0 Kernel: Add fast-path for sys$gettid() 
The userspace locks are very aggressively calling sys$gettid() to find
out which thread ID they have.

Since syscalls are quite heavy, this can get very expensive for some
programs. This patch adds a fast-path for sys$gettid(), which makes it
skip all of the usual syscall validation and just return the thread ID
right away.

This cuts Kernel/Process.cpp compile time by ~18%, from ~29 to ~24 sec.
