949440623b Return correct error code to user-space when a system call receives a 
signal in the LinuxKPI.

The read(), write() and mmap() system calls can return either EINTR or
ERESTART upon receiving a signal. Add code to figure out the correct
return value by temporarily storing the return code from the relevant
FreeBSD kernel APIs in the Linux task structure.

67dcd64ab8 linuxkpi: Do not leak pages on put. 
When the owner of the wire reference releases the last reference, it
might be that the page was already attempted to be freed (but free
cannot be performed at that time due to wire).  Check that the page
was removed from the object as the indicator of the free attempt and
finish the free operation if so.
