[PATCH] dm-ioctl: replace dm_[add|remove]_wait_queue() with dm_wait_event()
From: Kevin Corry <kevcorry@us.ibm.com>
Some testing of DM multipath has turned up a problem with the DEVICE_WAIT
command. In the tests, while performing a DEVICE_WAIT on a multipath device,
the command sometimes returns immediately, even though the event-number is
correct and no path-failure has occurred to trigger an event. The problem was
tracked down to the call to schedule() in dev_wait(), which would return even
though it was not woken up by a DM table event.
This patch moves the responsibility for waiting from the ioctl interface into
the core driver, and uses wait_event_interruptible() instead of relying on
wait-queues and schedule().

[PATCH] i386: put irq stacks in .bss.page_aligned section
From: Matt Mackall <mpm@selenic.com>
I noticed that my vmlinux BSS had grown from 17k to 45k between 2.6.5 and
2.6.6. 8k was moving a pair of objects in head.S from the text section to
bss, 8k was the introduction of IRQ stacks, while the remainder (12k) was
page alignment slop, some of it spurious. The following patch brings BSS
down to the expected 33k.
Throw the IRQ stacks into the page aligned section to avoided wasted BSS
space. While we'd expect this to save up to 4k, this saves over 10k of BSS
here due to gcc3.3 spuriously aligning other objects in the vicinity.

[PATCH] ppc64: remove silly debug path from get_vsid()
From: David Gibson <david@gibson.dropbear.id.au>
Currently the get_vsid() and get_kernel_vsid() functions have a test which
enables a different VSID algorithm for debugging. Using a dumb VSID
algorithm for stressing the hash table is a reasonable debugging tool, but
switching it at runtime makes no sense at all. Plus it adds another test
and memory access to the performance critical SLB miss path.
This patch removes the test, replacing it with a compile time switch. It
seems to make a measurable, although small speedup to the SLB miss path
(maybe 0.5%).

[PATCH] Leave runtime suspended devices off at system resume
Currently all devices are resumed at system resume time, including any
that were individually powered off ("at runtime") prior to the system
suspend. In certain cases it can be nice to force back on individually
suspended devices, such as the display, but hopefully this policy can be
left up to userspace power managers; the kernel should probably honor
the settings previously made by userspace/drivers. This seems
preferable to requiring a power-conscious system to re-suspend devices
after a system resume; furthermore, for certain platforms (such as
XScale PXA27X) there can be disastrous consequences of powering up
devices when the system is in a state incompatible with operation of the
device.
Suggested patch does this:
(1) At system resume, checks power_state to see if the device was
suspended prior to system suspend, and skips powering on the device if
so.
(2) Does not re-suspend an already-suspended device at system suspend
(using a different method than is currently employed, which reorders the
list, see #3).
(3) Preserves the active/off device list order despite the above changes
to suspend/resume behavior, to avoid dependency problems that tend to
occur when the list is reordered.

[PATCH] Device runtime suspend/resume fixes
(1) Set device power state at runtime resume (as is done for runtime
suspend) so that a later suspend does not think the device is still
suspended (refusing to suspend it again).
(2) Move devices from the active list to the off list only when
suspending all devices as part of a system suspend, not for runtime
suspend. This matches the resume code, which only moves devices from
off to active during system resume, such that runtime resume currently
doesn't move the suspended device back to the active list. (This also
avoids reordering the device list for runtime suspends; the list is in
order of registration and suspend/resume works best that way -- granted,
more sweeping improvements in how device dependencies are accounted for
in the suspend/resume order are also needed someday.)
Runtime device suspend/resume is in some cases used frequently on
battery-powered embedded devices, to save additional power and to handle
device power state interactions with overall system power state on
certain platforms.

[netdrvr ixgb] massive update
Since Intel agreed to submit further updates via broken-up patches
like they do currently (and admirably) for e1000 and e100, I agreed
to merge this update to bring the driver up to speed.
Contributed by: Ayyappan.Veeraiyan@intel.com
Changes:
Features implemented
* Support for new 850nm adapters.
* Copyright notice updated to include year 2004.
* Fix for "ixgb does not maintain non-default MTU setting across a
link loss" issue - When link loss happens in non-default MTU
environment, driver will incorrectly operate with default 1500 MTU
setting.
* Netpoll support added
* Ethtool support - status functionality, FlowControl interface,
Checksum interface, TSO and Scatter Gather interfaces
* Race condition fix - Race condition (TX path) exists between
ixgb_xmit_frame and clean_tx_irq routines in handling the queue.
* Removed dead code segments (#if 0)
Performance improvement features
* Mod operator usage is removed - used to cause performance
problems in non-IA architecture based machines
* Multiple ICR register read in ISR is avoided
* RS bit set on only 'end of packet' TX descriptors - to avoid
multiple writebacks by controller for packets with multiple descriptors.
* RX descriptors prefetch is done - improved 1500 MTU TX
performance
All relevant e1000 driver cleanups ported to ixgb
* Valid error propagation in functions ixgb_up, ixgb_probe,
ixgb_open.
* NAPI code cleanups
* u8, u16 and u32 data types are changed to uint8_t, uint16_t and
uint32_t respectively. We use these types on our shared code for
multiple OSes and also to make it uniform with e1000 driver.
* Some functions in ixgb_main.c are moved to different location -
This enables easy porting of e1000 bug fixes to ixgb
