Apparently our thread-creation performance has gone down the tubes again,
because the mm.free_area_cache search heuristic broke.

The initial, more naive hole-cache patch helped the testcode in the
beginning.  Then after some point glibc started creating a 'small hole' in
the vmas, which hole was _below_ the thread stacks, and which hole thus
prevented the intended operation of the cache.

The new code solves the problem by relaxing the 'smallest address hole cache'
rule a bit, the cache is now not re-set at every get_unmapped_area() time,
it's only re-set during unmaps.  It's also re-set if there are no allocatable
mappings at all - ie.  correctness is not affected.

Give the ia32 vsyscall DSO the same name as ia64's.

This patch adds an AT_SECURE auxv entry to pass a boolean flag indicating
whether "secure mode" should be enabled (i.e.  sanitize the environment,
initial descriptors, etc) and allows each security module to specify the
flag value via a new hook.

New userland can then simply obey this flag when present rather than
applying other methods of deciding (sample patch for glibc-2.3.2 can be
found at http://www.cs.utah.edu/~sds/glibc-secureexec.patch).

This change enables security modules like SELinux to request secure mode
upon changes to other security attributes (e.g.  capabilities,
roles/domains, etc) in addition to uid/gid changes or even to completely
override the legacy logic.

The legacy decision algorithm is preserved in the default hook functions
for the dummy and capability security modules.

Credit for the idea of adding an AT_SECURE auxv entry goes to Roland
McGrath.

- unused var warning in pnp_add_irq_resource()

- unused var in fd_mcs.c (Adrian Bunk)

- remove dead code in i810_main.c (a u8 cannot exceed 255) (Adrian Bunk)

- don't truncate dma_addr_t's in gdth.c (Jes Sorensen)

- vgastate.c needs vmalloc.h (Geert Uytterhoeven <geert@linux-m68k.org>)

- revert bogus test from rd_open() - it was a 2.4 forward-port, and 2.5
  doesn't need it.  (The gendisks aren't registered, we cannot get there
  anyway).

Basically, the problem is that setscheduler() does not set need_resched
when needed.  There are two basic cases where this is needed:

	- the task is running, but now it is no longer the highest
	  priority task on the rq
	- the task is not running, but now it is the highest
	  priority task on the rq

In either case, we need to set need_resched to invoke the scheduler.

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.
