This corrects the save/restore code in mca_asm.S
which was written long ago, before the assembler understood
mnemonic names for 'cr' and 'ar' registers (in fact it
appears to have been written pre-silicon, some of the
control register numbers don't match with what actually
got built).  There were other goofs too (like using
0, 1, 2, etc. for region register subscripts).

Now that the ACPI table parsing stuff has been fixed we can move
find_memory() back where it belongs--after the SRAT table has been
parsed.

This patch fixes the combination of CONFIG_DISCONTIGMEM and
CONFIG_VIRTUAL_MEM_MAP so that generic kernels will work on all ia64
platforms, including sn2, and also makes sn2 specific kernels work
(which I think is a first).

I've cleaned this patch up heavily based on feedback from yourself,
Christoph and others.  I've tested sn2, zx1, and dig (thanks Xavier!)
specific configurations, as well as a generic configuration that allows
the same binary to boot on zx1, dig, and sn2.

This fixes a misnomer of some syscalls in 2.6.0-test[567].  Glibc wants
them without the sys_ infix.

Patch from Christoph.  Fixes interrupt allocation code for sn2.

This seems to be introduced by recent changes in 2.6.0-test series.

GAS_HAS_LOCAL_TAGS was removed a long time ago, but uaccess.h never got
updated.  Without this fix, bad syscall args may cause a SEGFAULT instead
of failing gracefully.

Here is a patch that adds numa support for hugetlb page on ia64.  It is
taken from x86 numa implementation.  The low level hugetlb page
pre-allocation is done in round robin fashion on each numa node and
allocation for user level code is node local aware.

n platforms without an SRAT (e.g. zx1), the cpu_to_node_map will get
built incorrectly without this fix, making generic kernels fail when
they try to alloc_pages_node() from a nodeid of -1.

Small fix to build early_sn_setup even if early printk is turned off.

I didn't realize that any_online_cpu() wouldn't work for
is_headless_node(), so this patch reverts the function back to using the
node_to_cpu_mask[] array, fixing sn2 for systems with less than 64p.

Don't try to use the sn2 I/O code if we're not on sn2 or we may get into
trouble.  Only makes a difference for generic kernels.

I ran into some bugs testing epoll in ia32-emulation mode on ia64.
The attached patch fixes the problems and is well tested.
Here is a summary of the changes:

Changes to sys32_epoll_ctl() and sys32_epoll_wait():
- changed epoll_event32.data to an array (this is subjective, but seems
to make the code more readable)

Changes to sys32_epoll_wait():
- added call to __get_free_pages if kmalloc(epoll_event array) fails.  This
  provides needed scalability and fixes the -ENOMEM failure during
epoll-pipetest.
- deleted copy-in of epoll_event array since this is not a user-inputsyscall
- changed to check numevents > 0 as indicator of success on call to
  sys_epoll_wait.
- changed to loop on numevents not maxevents when copying out to userspace.

Replace read/write lock used for HPET timer monotonic_lock with seqlock.
Similar to locking used on xtime and monotonic_lock in timers/timer_tsc.c

Replace read/write lock used for cyclone timer monotonic_lock with seqlock.
Similar to locking used on xtime and monotonic_lock in timers/timer_tsc.c

breaks everybody else.

Instead, fix the NOMMU case by avoiding the part that walks page
tables.

 - fix VIDIOC_S_FBUF for v4l1 backward compatility with xfree86 / v4l_drv

 - some progress on DVB-C analog module: experimentally fix frequency
   offset, initialize msp3400 for analog TV sound
 - Reduce the number of dropped TS packets when an error is detected
   (Jon Burgess)
 - If somebody calls G_TUNER for a DVB-C card w/ analog module, then
   check for the selected tuner, not if the currently selected channel
   has a tuner.
 - play_iframe may be used to play stillpicture frames, that can either
   by complete i-frames or partial p-frames.  In any case, the av7110
   needs about 400kB of video data, before the internal video decoder
   starts displaying anything.  for stillframes, this is bad, so we
   *always* loop writing the frame until the magic amount is reached.
   stupid, but works... 
 - applied 64bit fixes by Pedro Miguel Teixeira <pmsjt@warner.homeip.net

 - split up saa7146 compilation in core part (saa7146.o) and video+vbi
   part (saa7146_vv).  some drivers need both (av7110.c), some drivers
   only need the core stuff (budget*.c)
 - add entry for sp887x DVB-T modulator to corresponding Kconfig
 - use new SELECT facility of Kconfig, first mentioned by Adrian Bunk
   and Roman Zippel in DVB subsystem
 - use SELECT in media/video/Kconfig, too.

 - add budget driver as possible client of the ves1820 frontend driver
 - fix wrong include in sp887x.c frontend driver
 - fix wrong chip description in tda1004xh frontend driver
 - fixed detection of stv0299 if chip is in standby mode
 - change some #ifdef to #if, for easier debug enable/disable
 - ves1820: patch by Peter Bieringer: nicer log output
 - ves1820: allow PWM (tuner calibaration) value from EEPROM to be
   overridden on command line (based on patch by Peter Bieringer).  New
   module paramters: "pwm" (max 4 ints, range -1..0xff) and "verbose"
   (to print AFC value aftger tuning).

 - various av7110 updates

 - patch by Jon Burgess to fix DMA issues
 - reduce the number of dropped TS packets when an error is detected
   (Jon Burgess)
 - use budget-ci driver for new TT DVB-T cards with onboard MSP430.

 - the usual c99 initialization fixes all over the DVB place

 - fix copyright stuff in various files:
   - remove e-mail addresses that don't exist anymore, but of course keep
     the names
   - change license from GPL to LGPL in dvb_i2c.h (Convergence code)
   - change license from GPL to LGPL in dvb_ringbuffer.h (ack by original
     author Oliver Endriss)
   - add LGPL license to dvb_functions

 - allow multiple read device opens

 - some Kconfig simplifications
 - FIELD_ALTERNATE capture was broken, add a "wait for vbi" command
   before actually waiting for the field change
 - improvements regarding streaming capture to gfx card memory.
 - captured frames could only be page aligned.  fixed.
 - fix pgtable_build_single, it should work for all kinds of buffers now
   (system memory (kernel/user) and gfx-memory)
 - Fix bytesperline-calculation for V4L2_FIELD_ALTERNATE vs.
   V4L2_FIELD_INTERLACED capture
