[Patch 05/25] GRU - cbe cache flush
From: Jack Steiner <steiner(a)> In some cases, for performance reasons flushing the SGI GRU cbe needs to dirty the cacheline before doing the cacheline flush. This ensures that the dirty cacheline actually goes back to the caching home agent. Update a reserved field in the CBE instead of a field that might b... 19 Jul 2010 17:58
[Patch 08/25] GRU - flush gru tlb when driver is loaded
From: Jack Steiner <steiner(a)> Flush the GRU TLB when the GRU driver is loaded. There may be stale entries in the TLB if a previous GRU was unloaded since the system was last reset.

[PATCH] timer: Added usleep[_range][_interruptible] timer
*** INTRO *** As discussed here ( ), msleep(1) is not precise enough for many drivers (yes, sleep precision is an unfair notion, but consistently sleeping for ~an order of magnitude greater than requested is worth fixing). This patch adds a usleep API so that udelay does not have... 19 Jul 2010 17:58
[PATCH] LEDS: Add output invertion option to backlight trigger
This patch extends the LED backlight tirgger driver with an option that allows for inverting the trigger output polarity. Whith the invertion option provided, I (ab)use the backlight trigger for driving a led that indicates LCD display blank condtition on my Amstrad Delta videophone. Since the machine has no d... 19 Jul 2010 16:52
pull request: wireless-2.6 2010-07-19
Dave, In this round we have two more-or-less-one-liners intended for 2.6.25. The hostap fix is the third (and hopefully final) bite at the apple for correcting an initialization failure. The first two attempts created and then reinstated a regression caused by a discrepency between the PCI and PCMCIA support ... 19 Jul 2010 15:46
[PATCH] trivial: Use correct macro to display sched_child_runs_first in /proc/sched_debug
Resending via git. The sched_child_runs_first value in /proc/sched_debug is currently displayed using a macro meant to split ns time values. This patch uses the correct macro to display it as a plain decimal value. Signed-off-by: Josh Hunt <johunt(a)> --- kernel/sched_debug.c | 2 +- 1 files chan... 19 Jul 2010 15:46
usbnet: fix 100% CPU use on suspended device
This patch causes the usbnet module not to attempt to submit URBs to the device if the device is not ready to accept them. Looks plausible to me; can't test it or review the underlying bug though. This fixes a misbehavior trigged by the Qualcomm Gobi driver (released under GPL through their Co... 19 Jul 2010 15:46
[PATCH -V17 05/12] vfs: Support null pathname in readlink
From: NeilBrown <neilb(a)> This enables to use readlink to get the link target name from a file descriptor point to the link. This can be used with open_by_handle syscall that returns a file descriptor for a link. We can then use this file descriptor to get the target name. This is similar to utimensat(2)... 19 Jul 2010 15:46
