[PATCHv3 03/16] pps: fix race in PPS_FETCH handler
There was a race in PPS_FETCH ioctl handler when several processes want to obtain PPS data simultaneously using sleeping PPS_FETCH. They all sleep most of the time in the system call. With the old approach when the first process waiting on the pps queue is waken up it makes new system call right away and zeroes pps... 4 Aug 2010 17:59

[PATCHv3 08/16] pps: add async PPS event handler
This handler should be called from an IRQ handler. It uses per-device workqueue internally.

[PATCH v2] isofs: Fix lseek() to position beyond 4 GB
isofs supports files larger than 4 GB by using multi-extent files. However an lseek() to a position beyond 4 GB in such a file will fail with EINVAL, because s_maxbytes in the isofs superblock is initialized to 2^32-1, and generic_file_llseek() checks against that value. I therefore suggest increasing the value ... 4 Aug 2010 17:59

[PATCH] x86/apic: Map the local apic when parsing the MP table.
This fixes a regression in 2.6.35 from 2.6.34, that is present for select models of Intel cpus when people are using an MP table. The commit cf7500c0ea133d66f8449d86392d83f840102632 "x86, ioapic: In mpparse use mp_register_ioapic" started calling mp_register_ioapic from MP_ioapic_info. An extremely simple ch... 4 Aug 2010 16:54

excessive wakeups in 2.6.35
My laptop felt like it was about to burst into flames after I ran 2.6.35 on it for a while. It actually got too hot to place on my legs. Powertop showed it running over a 1000 wakeups a second while completely idle. Chuck Ebbert pointed me at this diff.. http://git.kernel.org/?p=linux/kernel/git/x86/linux-2.6-ti... 5 Aug 2010 00:31

Despecificate driver from iLO2
Hi Dan, This driver supports both iLO2 and iLO3, but our user-visible strings currently only reference iLO2. Let's just call it "iLO" to avoid having to update strings for each iLO generation. This driver doesn't support iLO ASICs prior to iLO2, but that is sufficiently explained in Kconfig. Just a tho... 5 Aug 2010 01:36
