tcp: input header length, prediction, and timestamp bugs
From: William Allen Simpson <william.allen.simpson(a)gmail.com> Date: Sun, 14 Feb 2010 01:21:35 -0500 Don't use output calculated tp->tcp_header_len for input decisions. While the output header is usually the same as the input (same options in both directions), that's a poor assumption. In particular, Sack ... 17 Feb 2010 19:04

[PATCH 1/8] PCI PM: Add function for checking PME status of devices
From: Rafael J. Wysocki <rjw(a)sisk.pl> Add function pci_check_pme_status() that will check the PME status bit of given device and clear it along with the PME enable bit. It will be necessary for PCI run-time power management. Based on a patch from Shaohua Li <shaohua.li(a)intel.com> Signed-off-by: Rafael J. Wy... 17 Feb 2010 17:55

x86-32: use SSE for atomic64_read/set if available
On 02/17/2010 03:42 AM, Luca Barbieri wrote: This patch uses SSE movlps to perform 64-bit atomic reads and writes. According to Intel manuals, all aligned 64-bit reads and writes are atomically, which should include movlps. To do this, we need to disable preempt, clts if TS was set, and restore T... 18 Feb 2010 15:07

boot times, not mdadm (was: Linux mdadm superblock question.)
also sprach Nick Bowler <nbowler(a)elliptictech.com> [2010.02.18.1037 +1300]: the assembly time would probably be the same, but the initramfs being proposed did not include that time either. This was the *only* time that was included. Quoting myself: If you are discussing boot times rather than mdad... 17 Feb 2010 17:55
