Switch trident to use pci_get/put_dev properly. Also fix a bug where the
driver erroneously passed pdev not NULL to a second search. This happened

This is one of a series of patches I plan to gradually trickle into the
tree which eliminates almost all remaining use of pci_find_* and lets me
build a pci_find_* free kernel for all but some obscure ISDN and SCSI
drivers. This is important as all pci_find_* users are not hotplug safe -
even if they are not the device being plugged.Signed-off-by: Alan Cox

ppc can boot one single binary on prep, chrp and pmac boards. ppc64 can
boot one single binary on pseries and G5 boards. pmac has no legacy io,
probing for PC style legacy hardware (or accessing the legacy io area
regulary) may lead to a hard crash:* add check for parport_pc, exit on pmac. 32bit chrp has no
->check_legacy_ioport, the probe is always called. 64bit chrp has
check_legacy_ioport, check for a "parallel" node* add check for isapnp, only PReP boards may have real ISA slots. 32bit
PReP will have no ->check_legacy_ioport, the probe is always called.* update code in i8042_platform_init. Run ->check_legacy_ioport first,
always call request_region. No functional change. Remove whitespace
before i8042_reset init.Signed-off-by: Olaf Hering

This patch adds the ability to register for a command per-channel in the
IPMI driver.If your BMC supports multiple channels, incoming messages can be useful to
have the ability to register to receive commands on a specific channel

Use the new diagnose 0x9c in the spinlock implementation for s390. It

Powerpc already has a directed yield for CONFIG_PREEMPT="n". To make it
work with CONFIG_PREEMPT="y" as well the _raw_{spin,read,write}_relax
primitives need to be defined to call __spin_yield() for spinlocks and
__rw_yield() for rw-locks.Acked-by: Paul Mackerras

On systems running with virtual cpus there is optimization potential in
regard to spinlocks and rw-locks. If the virtual cpu that has taken a lock
is known to a cpu that wants to acquire the same lock it is beneficial to
yield the timeslice of the virtual cpu in favour of the cpu that has the
lock (directed yield).With CONFIG_PREEMPT="n" this can be implemented by the architecture without
common code changes. Powerpc already does this.With CONFIG_PREEMPT="y" the lock loops are coded with _raw_spin_trylock,
_raw_read_trylock and _raw_write_trylock in kernel/spinlock.c. If the lock
could not be taken cpu_relax is called. A directed yield is not possible
because cpu_relax doesn't know anything about the lock. To be able to
yield the lock in favour of the current lock holder variants of cpu_relax
for spinlocks and rw-locks are needed. The new _raw_spin_relax,
_raw_read_relax and _raw_write_relax primitives differ from cpu_relax
insofar that they have an argument: a pointer to the lock structure.Signed-off-by: Martin Schwidefsky

I was playing with LED triggers when I noticed that changing from heartbeat
(or ide-disk) to "none" at the right moment would leave the LED stuck on.
This is easy to reproduce by doing "find / >/dev/null" with the ide-disk
trigger enabled and then switching to "none".Here is a patch that fixes the problem by explicitly turning the LED off
after removing the existing trigger.Signed-off-by: Paul Collins

The driver for /proc/config.gz consumes rather a lot of memory and it is in
fact possible to build it as a module.In some ways this is a bit risky, because the .config which is used for
compiling kernel/configs.c isn't necessarily the same as the .config which was
used to build vmlinux.But OTOH the potential memory savings are decent, and it'd be fairly dumb to
build your configs.o with a different .config.Signed-off-by: Andrew Morton
