3468a6b33d Change MS_SYNC to MS_ASYNC 
Hopefully this makes the address validation a bit cheaper.

54752e0df0 Implement getcontext for x86 
Greetings,

Attached patch implements getcontext for x86.

Motivation is the same as:
http://lists.nongnu.org/archive/html/libunwind-devel/2008-06/msg00009.html

This also fixes check-name-space on x86.

Tested on Linux/86 with no new failures.

Thanks,

0cf76ed0b5 Check for NULL when validating addresses 
This is rather on the obvious side.

While doing strace on an executable using libunwind, I noticed a
lot of:

  msync(0, 1, MS_SYNC) = -1 ENOMEM (Cannot allocate memory)

Since we know that the first page isn't mapped (or at least doesn't
contain the data we are looking for), we can eliminate all such
msync calls.

Tested on Linux/x86_64 with no regressions.
