2007-04-30power management: implement pm_ops.valid for everybodyJohannes Berg
Almost all users of pm_ops only support mem sleep, don't check in .valid and don't reject any others in .prepare so users can be confused if they check /sys/power/state, especially when new states are added (these would then result in s-t-r although they're supposed to be something different). This patch implements a generic pm_valid_only_mem function that is then exported for users and puts it to use in almost all existing pm_ops.

2007-04-30[BLOCK] Don't pin lots of memory in mempoolsJens Axboe
Currently we scale the mempool sizes depending on memory installed in the machine, except for the bio pool itself which sits at a fixed 256 entry pre-allocation. There's really no point in "optimizing" this OOM path, we just need enough preallocated to make progress. A single unit is enough, lets scale it down to 2 just to be on the safe side. This patch saves ~150kb of pinned kernel memory on a 32-bit box. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-04-30[POWERPC] Remove dev_dbg redefinition in drivers/ps3/vuart.cPaul Mackerras
Commit 404d5b185b4eb56d6fa2f7bd27833f8df1c38ce4 changed the definition of dev_dbg in the !DEBUG case from being a #define to being a static inline. There was code in drivers/ps3/vuart.c to do exactly that, which fails to compile now. This fixes it by removing the redefinition, as the redefinition is now superfluous.

2007-04-30ieee1394: eth1394: don't autoload by hotplug when ohci1394 startsStefan Richter
Until now, ieee1394 put an IP-over-1394 capability entry into each new host's config ROM. As soon as the controller was initialized --- i.e. right after modprobe ohci1394 --- this entry triggered a hotplug event which typically caused auto-loading of eth1394. This irritated or annoyed many users and distributors. Of course they could blacklist eth1394, but then ieee1394 wrongly advertized IP-over- 1394 capability to the FireWire bus. Therefore - remove the offending kernel config option IEEE1394_CONFIG_ROM_IP1394, - let eth1394 add the ROM entry by itself, i.e. only after eth1394 was loaded. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=7793 . To emulate the behaviour of older kernels, simply add the following to to /etc/modprobe.conf: install ohci1394 /sbin/modprobe eth1394; \ /sbin/modprobe --ignore-install ohci1394 Note, autoloading of eth1394 when an _external_ IP-over-1394 capable device is discovered is _not_ affected by this patch.
