Newer gcc changes alignment flags from a -m to -f

Some revisions of the AMD8131 PCI-X bridge have a irq routing bug that appears
in IO-APIC mode. To work around it a bit needs to be set in this case.

This adds the x86-64 ELF relocations to include/linux/elf.h

This is needed for the new module loader.

This patch depends on the i386 MTRR driver cleanup I sent earlier.

 - Support non executable mappings for x86-64. data/heap are non executable
   by default now.
 - Beginnings of software suspend from Pavel (not working yet)
 - Support generic compat functions and remove some shared code
   in the 32bit emulation (Stephen Rothwell)
 - Support hugetlbfs
 - Some makefile updates
 - Make sure all 32bit emulation functions return long, not int.
   This fixes some problems with ERESTARTNOSYS.et.al. leaking to userspace.
 - Add new system calls.
 - Fix long standing fs/gs context switch bugs (thanks to Karsten Keil
   for helping to fix that mess). Also make sure the gs selector is
   set to 0 after an exec.
 - Simplify TLS switching
 - Paranoid CPUID check at bootup
 - Reorder scatterlist to be more space efficient (Jes Soerensen)
 - Enlarge 32bit address space to full 4GB.
 - Beginnings of 32bit SYSCALL support (not completely working yet
   and vsyscall page miss yet)
 - Various merges from i386
 - New module loader
 - Support threaded core dump (XMM saving for 32bit programs doesn't
   work, but it appears to be broken on i386 too)
 - Fix bug in signal stack rounding
 - Remove DRM 32bit emulation.
 - Use MTRR driver from i386
 - Use bootflag.c from i386
 - Various other fixes and cleanups.

This does:
 - fix one warning in bootflag.c
 - change a few longs to int and int to long in the MTRR driver
   to make it 64bit clean (should be a NOP for 32bit i386, but is needed
   for x86-64)
 - Convert the MTRR /proc interface to seq_file and remove the broken
   compute_ascii() hack.  This fixes some broken code e.g.  the old
   mtrr_write was completely broken because the loop checking for
   commands started with a "continue" - remove duplicated mtrr type
   strings.

Update scsi_scan so that we don't pass around a scsi_device struct for
    	scanning.  Instead, we pass around a request_queue during
    	scanning and create and destroy device structs as needed.  This
    	allows us to have a 1:1 correlation between scsi_alloc_sdev()
    	and scsi_free_sdev() calls, which we didn't have before.

[AGP] agp_frontend_initialize() now gets called when a chipset driver registers, so it can't be __init any more.

Based on a patch from Andrew Morton.

Also checks to see if the sd device is bigger than the kernel can
support and prints out a warning in that case

This makes the following changes :
 o headers cleanup
 o remove deprecated kernel_only
 o mention minimum oprofile version
 o correct initialise stats
 o remove racy debug check (wli saw this oops)
 o remove pointless simple_open
 o add dump functionality
 o remove pessimising FASTCALL

It fixes a critical race.

This simple intermezzo Makefile change allows it to build.

OK'ed by Peter Braam.

This fixes the APM GDT entry allocation issue.  Confirmed by Andrew
Morton.

fast system calls. They should now be fully comparable to
traditional system calls.

    Fix SEP stack allocation to look like a real thread stack.
    
    This fixes the "Trap on first sysenter instruction" problem,
    which can happen either as a result of an NMI or a breakpoint
    trap (TF bit set).
    
    Also make the user trampoline save and restore EFLAGS, so that
    the TF bit gets restored after a fast system call (it will have
    been cleared to avoid trap faults in the kernel).
