Make the PCMCIA client drivers depend on hisax.o, 
use the right CONFIG_ variable for hisax submodules,
handle the case of built-in hisax, modular hisax submodules.

Remove the repeated information on what a module is.

This patch brings 2.5.8 in sync with the x86-64 2.4 development tree again
(excluding device drivers)

It has lots of bug fixes and enhancements. It only touches architecture
specific files.

- Sync with 2.5.8
- SMP/APIC supported now.
- Module loading works now.
- Time keeping bugs fixed.
- entry.S streamlined and some bugs fixed.
- modify_ldt works now
- mostly rewritten FPU support (including FXRSTOR for initial FPU
  initialization based on the initial state)
- 32bit emulation enhanced and bugs fixed.
- rewrote mm initialization and lots of cleanups in the page table handling
  __PAGE_OFFSET is now moved to 0x10000000000 and some vmalloc/ioremap
  problems have been fixed. They have an own PML4 slot now.
- WCHAN reporting support for RIP (but not RSP)
- Lots of various other bug fixes and cleanups.

Currently broken:
- ACPI
- MTRR

It needs some other bugfixes outside architecture specific code. I sent
them all in separate mail.

When vt_init happens to run before the keyboard is initialized (the order is random
because they're both different initcalls) then set_leds raises an not yet enabled
tasklet. This causes an endless loop on the first schedule() call because the tasklet
handling cannot handle raised but disabled tasklets.

This patch just does not do set_leds in virtual terminal initialization to avoid that.
It is done later anyways.

Minor patch for the x86-64 32bit emulation. Originally proposed by hpa and it
makes autofs 32bit/64bit clean for x86-64

Initialize the saved FPU/XMM state in the task struct and fall through
to restore_fpu() to make sure that all state is fully initialized.

This means that old SSE/SSE2 information cannot ever leak into newly
created processes. 

 - (tcq, general) Remove the 'attempt to keep queue full option'. It worked
   on some IBM models, but failed miserably on others. Also removes some
   uglies in ide_queue_commands()

 - (tcq0 Change default depth back to 32.

 - (general) Add isr for no-dataphase taskfile, like task_no_data_intr but
   doesn't complain about failure. This is handy for commands what we _know_
   will fail, such as WIN_NOP.

 - (general) ide_cmd_type_parser() must set a handler to WIN_NOP... Otherwise
   we will just hang the ide system issuing a nop.

 - (general) HWGROUP(drive)->rq->special -> IDE_CUR_AR(drive)

 - (general) Have ide_raw_taskfile() copy back the taskfile after execution,
   otherwise we cannot use the info that ide_end_drive_cmd() puts in
   there.

 - (tcq) Use nIEN bit correctly in ide-tcq

 - (tcq) Small ide_tcq_wait_altstat() changes. Do initial 400ns delay (1us
   here), then 10us each successive run.

 - (tcq) Add beginning for 'nop auto poll' support check.

 - (tcq) Arm handler before GET_STAT() service check in
   ide_dma_queued_start, WD seemed to trigger interrupt before that.
   Makes WD Expert drives work with tcq.

I'm currently working on a node affine scheduler extension for NUMA
machines and the load balancer behaves a bit different from the original.
So after a few boot failures with those slowly booting 16 CPU IA64
machines I thought there must be a simpler solution than synchronizing and
waiting for the load balancer: just let migration_CPU0 do what it is
designed for. So my proposal is:
   - start all migration threads on CPU#0
   - initialize migration_CPU0 (trivial, reliable, as it already is on
     the right CPU)
   - let all other migration threads use set_cpus_allowed() to get to the
     right place

The only synchronization needed is the non-zero migration threads waiting
for migration_CPU0 to start working, which it will, as it is already on
the right CPU. This saves quite some lines of code.

I first posted this to LKML on March 6th (BTW, the fix #1, too) and since
then it was tested on several big NUMA platforms: 16 CPU NEC AzusA (IA64)
(also known as HP rx....), up to 32 CPU SGI IA64, 16 CPU IBM NUMA-Q
(IA32). No more lock-ups at boot since then. So I consider it working.

There is another good reason for this approach: the integration of the CPU
hotplug patch with the new scheduler becomes easier. One just needs to
create the new migration thread, it will move itself to the right CPU
without any additional magic (which you otherwise need because of the
synchronizations which won't be there at hotplug). Kimi Suganuma in the
neighboring cube is fiddling this out currently.

Attached is a patch that disables interrupts while holding the rq_lock.
This is certainly needed to prevent a race against the timer tick, as
Erich Focht pointed out.

- line ending white spaces squadron strikes back;
- some fscked tabs are fixed. Nice           after longs        coding sessions.

- just say no to +/-1 arithmetic when not needed;
- pot-pourri of misc cleanup;
- *new*: support of boot-time parameters

- CD/CTS change notification;
- more DEBUG/if (debug >...) conversion;

- guess what ? Code removal.

- useless code/comment removal;
- HOLD mode -> LxDA mode conversion.

- new functions for LxDA mode: dscc4_tx_done() and dscc4_tx_quiescent();
- dscc4_{rx/tx}_reset() should comply to errata sheet.

- dscc4_do_action() now looks like the others event waiting loops (may be
  called from interrupt context however);
- dscc4_start_xmit(): cosmetic before LxDA changes + mb() parano;
- dscc4_clock_setting(): only one return point, thanks;
- dscc4_priv() invocation removed from dscc4_xxx_settings;
- minor cleanups.

- code removal;
- turn old cruft into definitely modern cruft.

- DEBUG_PARANOIA was bad. "if (debug > x) {" is nice;
- state_check() now has only one return point;
- try_get_rx_skb() cosmetic;
- dscc4_rx_update() belongs to HOLD mode to LxDA changes;
- dscc4_wait_ack_cec() behaves like dscc4_xpr_ack();
- dscc4_rx_skb() refill logic is ready for LxDA mode and does everything
  to fulfill what its name suggests.
- document some errata voodoo in dscc4_init_one();
- dscc4_init_ring() should handle try_get_rx_skb() failure.

- dscc4_xpr_ack() busy waiting loop is modified so as to allow long
  delay without chewing too much cycles;
- more errata sheet magic;
- dscc4_set_clock() now has only one return point.

- space after "if"'s and "while"'s were missing here and there. Now it's easier to read
  after some hours in front of a computer.

- dscc4_patch_register() turns into scc_patchl() and should now avoid an
  hardware bug quoted in errata sheet;
- dscc4_init_registers() interface changes as any caller doesn't really need
  to poke into dscc4_dev_priv internal;
- scc_{writel/readl}() are added to access some buggy behaving registers;
- {read/write}l conversion to the previous functions
- dscc4_do_tx() sneaks, sorry. Belongs to HOLD -> LxDA changes.

- extra argument for dscc4_set_iface() (will be used in following patches).

- description update;
- more #defines;
- SCC_REG_START() change (shorter code);
- some noise.

This trivial patch will apply to both 2.4.19-pre7 and 2.5.8 with just line
offsets. It stops us from following a NULL pointer in classzone in the case
where there is a pgdat without a fully populated zone list (ie a node with
no ZONE_NORMAL on an ia32 NUMA machine). Without this patch, ia32
NUMA machines won't even boot - we dereference the classzone ptr
a few lines further down (or try to ;-) ).

The bug which Anton found.  On the
find_or_create_page->__find_lock_page path we're performing
a read_unlock of an rwlock which is held for writing.

The patch converts that to using a write_lock throughout.

Which penalises find_lock_page() a bit.  If it shows up
on profiles then we can clone __find_lock_page() and
use read_lock()s, but for now I'd opt for saving the
cache footprint.

Synchronize with Jens Axobe:

- Congruent ATA_AR_POOL fix to the ATA_AR_STATIC memmory corruption fix.

- Multi sector write handling fix.

- Fix drive capability deduction.

- Various other minor fixes.

- Fix typo in ide_cmd_ioctl().

- Fix typo in cris driver.

- Don't retry operations on medium errors. (pointed out by Eric Andersen).

- Attach the no_io_32bit, io_32bit, no_unmask, unmask and slow fields to the
   ata_channel instead of the ata_device structure. They are a property of the
   channel and not just the devices attached to it. This allowed us to fix the
   set_io_32bit function by removing the CONFIG_BLK_DEV_DTC2278 conditional. In
   fact initialization shows that this is fixing many other host chipsets as
   well since all of them did expect sometimes particular values for those
   parameters in paralell on both drives attached to a channel but we where
   allowed to apply different values on a per drive basis.

- The keep_settings flag is now unconditional and we don't mess with any
   channel parameters before drive reset. Some chipsets really really expect
   unconditionally that the tweaks they apply are always present and this wasn't
   honoured thus far! We are expecting the user to have good reasons for
   manually tweaking the settings.

- Don't reset io_32bit in ata_pre_reset() unconditionally. There are chipsets
   out there which expect io_32bit to be *allways* enabled!

- Remove many obsolete and nawadays just confusing documentation from ide.txt
