bk pull on ia64 linux tree

Hi Linus,

Please do a

	bk pull http://lia64.bkbits.net/to-linus-2.5

This will update the files shown below.

Apart from small SN2 fixes, there is a tiny but important fix to
pgtable.h.  It fixes breakage introduced by the Non-Exec stack patch
which caused the X server to get stuck.  The X server doesn't like it
if it can't turn on execute permission on the loaded modules...

Thanks!

   [PATCH] ia64: SN2 fix
   
   Move HW interrupt register init. to the proper place
   and don't force an interrupt if the IRQ is disabled
   or in progress.

<davidm@tiger.hpl.hp.com> (04/04/29 1.1606)
   ia64: Fix Exec-Only stack patch so X can work again.
   
   No pun intended, but X can't work if it can't turn on eXecute-permission
   on the some data pages...

<davidm@tiger.hpl.hp.com> (04/04/26 1.1371.1.539)
   [PATCH] ia64: BUG if smp_call_function is called with interrupts disabled
   
   smp_call_function() may not be called with interrupts disabled.
   Violating this precondition leads to bugs that are hard to reproduce
   and even harder to diagnose.  Thus, catch violations with BUG_ON().

<kaos@sgi.com> (04/04/26 1.1371.1.538)
   [PATCH] ia64: SN_SAL_PRINT_ERROR is reentrant
