Generate offsets for thread_info, cpuinfo_x86, and a few others instead of
hardcoding them.

It conflicts with the readq() I/O function.

Add disable param to capabilities module.  Similar to the SELinux param for
disabling at boot time.  This allows vendors to ship single binary image with
capabilities compiled statically, and disable it if they provide another
security model compiled as module.

Currently the readahead code tends to read one more page than it should with
seeky database-style loads.  This was to prevent bogus readahead triggering
when we step into the last page of the current window.

The patch removes that workaround and fixes up the suboptimal logic instead.


wrt the "rounding errors" mentioned in this patch, Ram provided the following
description:

  Say the i/o size is 20 pages.

  Our algorithm starts by a initial average i/o size of 'ra_pages/2' which
  is mostly say 16.

  Now every time we take a average, the 'average' progresses as follows
  (16+20)/2=18
  (18+20)/2=19
  (19+20)/2=19
  (19+20)/2=19.....
  and the rounding error makes it never touch 20

CONFIG_MAC_SERIAL (drivers/macintosh/macserial.c) is marked obsolete and

Missing spin_unlock in the error path.

From: Stephen Rothwell <sfr@au1.ibm.com>

This patch stops the iseries_veth driver trying to send every packet to too
many logical partitions.  Consequently, the number of transmit errors falls to
(about) zero from a very large number.  This should also improve performance a
bit as the driver is no longer doing 31 extra skb_clone()s and skb_free()s for
each packet.

From: Paul Mackerras <paulus@samba.org>

At present on ppc32, if the kernel accesses a bad address and causes an
oops, or drops into the xmon debugger, we only have the contents of the
volatile registers available to print.  The reason is that we only save the
volatile registers on entry for a page fault.

This patch restructures the code a bit so that if do_page_fault()
determines that the page fault is caused by a bad kernel access, it returns
to the caller, which then saves the full register set into the exception
frame before calling bad_page_fault().  This way we get the full set of
registers printed in the oops message.

From: Paul Mackerras <paulus@samba.org>

This patch adds module tags for the swim3 (macintosh floppy) driver.

blk_run_page() is incorrectly using page->mapping, which makes it racy against
removal from swapcache.

Make block_sync_page() use page_mapping(), and remove bkl_run_page(), which
only had one caller.

Split the system_state state `SYSTEM_SHUTDOWN' into SYSTEM_HALT,
SYSTEM_POWER_OFF and SYSTEM_RESTART and export system_state to modules.

This allows driver shutdown routines to know why they are being shutdown.  The
IDE subsystem wants this so that it knows to not spin the disks down across a
reboot.

This allows building the math-emu code as a module only when
CONFIG_SMP is not set. The fp trap handler cannot be preempted
on a single-CPU (as CONFIG_PREEMPT is not going to be supported
on alpha), so the module can be safely unloaded at any time.

Avoid warnings about truncating them when building the
name database.

Seperate function, cruft removed and old_hwif

With minor fixes from me

reiserfs_file_write unlocks the pages it operated on before updating
i_size.  This can lead to races with writepage, who checks i_size when
deciding how much of the file to zero out.

This patch also replaces SetPageReferenced with mark_page_accessed() in
reiserfs_file_write

This was verified to fix the BitKeeper data corruption problems that
Steven Cole has been debugging, where concurrent writes to a file and
writebacks to disk would cause zeroes in the file when CONFIG_PREEMPT
was enabled.

- clear hwif->hw in setup-pci.c before using it

- fix arch/arm/Kconfig to allow IDE only on platforms supporting it

- introduce IDE_ARCH_OBSOLETE_INIT and ide_default_io_ctl() so
  we can use generic ide_init_hwif_ports() and kill no longer needed
  <asm-arm/arch-*/ide.h> (leave broken lh7a40x and sa1100 versions)

Cross-compile tested on ARM.

Add drivers/ide/arm/ide_arm.c for simple default IDE interfaces
and clean obsolete ide_init_default_hwifs() implementations
in asm-arm/arch-{cl7500,rpc,shark}/ide.h and asm-arm26/ide.h.

This allows us to kill ide_init_default_hwifs() completely
in the next patch (because lh7a40x and sa1100 are broken).

Cross-compile tested on ARM.

* Convert all netdev->priv references to the fancy new netdev_priv().

* Reads/writes from/to eeprom using ethtool weren't working right
  on big-endian.  Now they are.

* Changed mapping on Rx skb to bi-directional.  skb->data holds both the
  RFD structure and the packet data, and the RFD is read/written by
  HW.  Issue found on Xscale HW that doesn't handle cache syncs auto-
  matically.  Other changes in patch are whitespace/spelling.
