bk pull on ia64 linux tree

Hi Linus,

please do a

	bk pull http://lia64.bkbits.net/linux-ia64-release-2.6.11

This will update the files shown below ... the apparently huge change
to ptrace.c is mostly code reformatting to fit in 80 columns.

Thanks!

-Tony

   [IA64] entry.S: .align in .text sections is broken, use TEXT_ALIGN()
   
   A few reports of illegal instruction panics while trying to boot
   were tracked to this.  Fix by David Mosberger.

   [IA64] fix ptrace debug-register handling bug
   
   I noticed that the PTRACE_POKEUSR code incorrectly clears bits 56-58
   of _all_ debug registers.  The intention was to only clear it for
   odd-numbered registers, to ensure that user-level can only set
   user-level data/instruction-breakpoints.  Patch below fixes this problem.
   The patch also replaces explicit clearing of the single-step and
   taken-branch PSR bits with a call to ptrace_disable() for PTRACE_KILL.

   [IA64] clean up pt_regs accesses
   
   This patch replaces the idiom:
   
   	func (args..., long stack) {
   		struct pt_regs *regs = (struct pt_regs *) &stack;
   
   with the more commonly used:
   
   	func (args..., struct pt_regs regs) {
   
   The latter didn't used to work with the very earliest kernels and
   compilers (anybody remember egcs?) but gcc-3.3 and probably even
   gcc-2.96 don't have a problem with it anymore.
   
   The change also makes sparse happier, since it doesn't like it when
   you access memory past the end of the declared size of that variable.

   [IA64] ptrace.c: Format to make it fit in 80 cols.
   
   David thinks this might make Jesse and Willy happy (or
   at least happier).  If they can cope with line breaks
   before a binary operator, rather than after, then maybe
   it will :-)
