sysrq-T currently displays the same stack trace for every process.

Teach show_stack() to look in the passed task_struct first if the caller did
not pass in a stack address.

2.5.73 removed the workaround needed to prevent gcc-2.95.x from
miscompiling spinlocks on UP.  It turns out that some versions of
gcc-2.95 still do have problems with empty structs, so re-introduce
the workaround.

Useful for testing hotplug issues with pci drivers.

Added needed release function, now all pci hotplug drivers need to implement
it...

 - Combine pci_alloc_primary_bus_parented into pci_scan_bus_parented.
 - Move the EXPORT_SYMBOL for pci_root_buses up to its definition.
 - Don't EXPORT_SYMBOL pci_scan_bus since it's a static inline.
 - Add the pci_domain_nr() to the sysfs name for this bus.

I noticed we have a couple of redundancies in drivers/pci/Makefile,
have a patch...

Add missing CONFIG_TC35805 entry to Kconfig.
Update CONFIG_NET_SB1250_MAC Kconfig entry.
Minor cosmetic updates to gt96100eth.

[ Registers of the world, unite! ]

This makes the IO-APIC data structures use unions, so that we can
cleanly access them both as flat "raw" values, and as the bitmap
sub-entries.

This error is handled in the signal delivery code and should never be
returned from a syscall unless a signal is pending.  Grepping seems to
indicate that that is in fact the case (but not for ERESTARTSYS, but
that is another problem).

Ignore earlier patch -- this one locks and free's as appropriate.
Tested on 2.5.72 with SMP.

Of course, it begs the question why have two (now three) versions of drivers for
the same hardware...

dev_ioctl already checks capable(CAP_NET_ADMIN), so no need to do so in
drivers.

Recently there has been a rash of Unexpected IO APIC reports on the
linux-smp mailing list.  Most of the most recent ones are due to some
newer Intel chipsets (865, 875).

The IO APIC Version register doesn't indicate the differences in these
IO APICs.

I have an patch that addresses these chipsets.  It has been tested by a
few people with good results and has been blessed by Maciej Rozycki.

Other than conditionally decoding IO APIC registers 2 and 3, we could
alternately ignore them since Linux doesn't use the values for anything
other than printing them.

This patch ignores IO APIC register 2 if it's the same value as IO APIC
register 1.  It also reads IO APIC register 3 if the IO APIC version is
>= 0x20, but some chipsets don't support this register, so it is also
ignored if its value if the same as IO APIC register 1 or 2.

Another possible(?) alternative is to read the PID/VID of the device to
determine which registers it supports.  However, PCI devices have not
been scanned at this point in init, so it would require scanning PCI
config space directly and I don't yet see the point of doing that.

Oh, and the UNEXPECTED_IO_APIC() function doesn't print anything in
2.5.current and I didn't change that.

This does the following:

 - IV value is current 512-byte sector relative to start of loop
   container file.  This is what all cryptoloop people have done, if I
   am not mistaken.  Andi or others - if you can demonstrate the need
   for a more flexible setup an additional ioctl field may be needed.  I
   hope we can do without.

 - made some things static

 - made lo_offset a loff_t

 - added lo_sizelimit

   If one wanted a (crypto)loop somewhere inside a container file, the
   old code allowed a starting offset, but no size, so that the
   cryptoloop always extended to the end of the container file.  This
   field allows one to select an arbitrary interval.  Note that this
   changes struct loop_info64.

 - improve error handling of loop_init()

 - removed the unused typedef transfer_proc_t.

 - added a define for LO_CRYPT_CRYPTOAPI

The semaphore in pnp_init_resource_table is not needed and, in some
cases, can cause resource management lockups.  This patch removes the
improperly placed semaphore.

In the last release, this api was accidently changed and therefore 
affected some drivers.  This patch corrects the issue by renaming
the api back to pnp_init_resource_table.
