If a signal is sent via kill() or tkill() the kernel fills in the wrong
PID value in the siginfo_t structure (obviously only if the handler has
SA_SIGINFO set).

POSIX specifies the the si_pid field is filled with the process ID, and
in Linux parlance that's the "thread group" ID, not the thread ID.

event (ie SIGSEGV, SIGFPE etc that happens as a result of a
trap as opposed to an external event), if the signal is
blocked we will not invoce a signal handler, we will just
kill the thread with the signal.

This is equivalent to what we do in the SIG_IGN case: you
cannot ignore or block synchronous signals, and if you try,
we'll just have to kill you.

We don't want to handle endless recursive faults, which the
old behaviour easily led to if the stack was bad, for example.

since some drivers seem to be unhappy about the 10-byte
version. 

The subsystem configuration can override this (eg USB or
ide-scsi).

- By default, do not try to probe the bus if the mainboard does not
  seems to support EISA (allow this behaviour to be changed through a
  command-line option).

- Use parent bridge device dma_mask as default for each discovered
  device.

- Probe the right number of EISA slots on PA-RISC. No more, no less.

- Now reserves I/O ranges according to EISA specs (four 256 bytes
  regions instead of a single 4KB region).

- By default, do not try to probe the bus if the mainboard does not
  seems to support EISA (allow this behaviour to be changed through a
  command-line option).

- Use parent bridge device dma_mask as default for each discovered
  device.

- Allow devices to be enabled or disabled from the kernel command line
  (useful for non-x86 platforms where the firmware simply disable
  devices it doesn't know about...).

trigger as per the "bk help triggers" suggestion, so that
we'll see any new triggers showing up in the tree.

Make it so.

  - Make use of the open intents to improve close-to-open
    cache consistency. Only force data cache revalidation when
    we're doing an open().

  - Add true exclusive create to NFSv3.

  - Optimize away the redundant ->lookup() to check for an
    existing file when we know that we're doing NFSv3 exclusive
    create.

  - Optimize away all ->permission() checks other than those for
    path traversal, open(), and sys_access().

   - Make the VFS pass the struct nameidata as an optional parameter
     to the permission() inode operation.

   - Patch may_create()/may_open() so it passes the struct nameidata from
     vfs_create()/open_namei() as an argument to permission().

   - Add an intent flag for the sys_access() function.

  - Make the VFS pass the struct nameidata as an optional argument
    to the create inode operation.
  - Patch vfs_create() to take a struct nameidata as an optional
    argument.

 - Add open intent information to the 'struct nameidata'.
 - Pass the struct nameidata as an optional parameter to the
   lookup() inode operation.
 - Pass the struct nameidata as an optional parameter to the
   d_revalidate() dentry operation.
 - Make link_path_walk() set the LOOKUP_CONTINUE flag in nd->flags instead
   of passing it as an extra parameter to d_revalidate().
 - Make open_namei(), and sys_uselib() set the open()/create() intent
   data.

Via irq routing has a funky PIRQD location.  I checked my datasheets
and, yep, this is correct all the way back to via686a.
This bug existed for _ages_.  I wonder if I created it, even...

follow by splitting it into two functions: one that calculates
the position, and the other that actually reads the inode
block off the disk.

uses it for now, but I needed it for some tuning tests,
and it is potentially useful for others.

This patch fixes a bad declaration of jiffies in timer_tsc.c and
timer_cyclone.c, replacing it with the proper usage of jiffies.h.

This patch corrects a trivial thinko in the manual resource api.

This patch updates the resource manager so that it actually assigns
disabled resources when they are requested by the device.

Some devices will allow for individual resources to be disabled,
even when the device as a whole is active.  The current PnP
resource manager is not handling this situation properly.  This
patch corrects the issue by detecting disabled resources and then
flagging them. The pnp layer will now skip over any disabled 
resources.  Interface updates have also been included so that we
can properly display resource tables when a resource is disabled.

Also note that a new flag "IORESOURCE_DISABLED" has been added to
linux/ioports.h.

Fixes the sysfs binary file bug.

 - Fix a couple of bugs in sysfs's handling of binary files (my fault).
 - Implement pci config space reads and writes in sysfs

Make pcibios_fixup_peer_bridges() use raw_pci_ops directly instead of
faking pci_bus and pci_dev.

Use pci_find_bus rather than relying on the return value of pci_scan_bus.

Convert all callers of pci_bus_exists() to call pci_find_bus() instead.
Since all callers of pci_find_bus() are __init or __devinit, mark it as
__devinit too.

Give pci_find_bus a domain argument and move its declaration to <linux/pci.h>

pci_sanity_check() is only called from functions marked __init, so it
can be __init too.

Fix some grammar problems
Add a note about Fast Back to Back support
Change the slot_name recommendation to pci_name().

used to work due to some random magic indirect include, but broke lately.

Do the obvious fix.
