- 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

   This patch has been floating inside IBM for a bit, but it appears
that no one passed it back up to you, yet.  I don't know who wrote it,
but it applies to 2.5.8 and the ServeRAID driver works just fine with it
applied.  Without it, the driver fails to compile.

Here is the patch to add the arch_consoles_callable() macro as was done
in the 2.4 tree.

This is the patch to add support for PR_SET_FPEMU/PR_GET_FPEMU to give
per-process control over fp-emulation handling.  It also cleans up the
way PR_SET_UNALIGN_CTL/PR_GET_UNALIGN_CTL are implemented.

Randy observed that 2.5 /proc/meminfo SwapFree holds steady
while SwapTotal goes up and down: wrong way round!

Andrew pointed to wrong conditional in si_swapinfo(): 2.5.4
updated it incorrectly when new flags bit was briefly added.
And pointed out that it also makes si_swapinfo much too slow.

The obvious patch to fix compiler warning when compiled with RH gcc 2.96
(and probably others too).

Finally, this changes set_bit et al. to take a "unsigned long *" on
ppc and i386.  This will make the world a better place.

Please forward patches for any warnings which crop up in random code
to trivial@rustcorp.com.au.

We have to include linux/bitops.h for arch using generic_xxx().

The following patch changes <asm/bitops.h> of include/linux/* to
<linux/bitops.h>.

Note patch compiles but is otherwise untested as no kernel after 2.5.7
boots on my 2.5 box due to IDE hanging the box hard during device
discovery. )-:

- Don't abuse the sense field for passing failed packet_commands in struct
   packet_command use a new field instead.

- Apply minor bits forwarded by Dave Jones to me.

- Fix ide_raw_taskfile() to flag the ar used there to be no subject of free_req
   list management. This solvs the "hang after /proc/ide read" problem, which
   was in fact a memory corruption problem.

- Consolidate ide_choose_drive() and choose_drive() in to one function.

- Remove sector data byteswpapping support. Byte-swapping the data is supported
   on the file-system level where applicable.  Byte-swapped interfaces are
   supported on a lower level anyway. And finally it was used inconsistently.

- Eliminate taskfile_input_data() and taskfile_output_data(). This allowed us
   to split up ideproc and eliminate the ugly action switch as well as the
   corresponding defines.

- Remove tons of unnecessary typedefs from ide.h

- Prepate the PIO read write code for soon overhaul.

- Misc small bits here and there :-).

very minor cleanup only (I want all references to list-multi gone ;-)

remove some long obsolete boilerplate code.
