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

 - add new DVB-T frontend driver sp887x.c

 - av7110 DVB driver firmware update.  don't worry: we're planning to
   switch to firmware_class soon...
