2011-02-11cifs: don't always drop malformed replies on the floor (try #3)Jeff Layton
Slight revision to this patch...use min_t() instead of conditional assignment. Also, remove the FIXME comment and replace it with the explanation that Steve gave earlier. After receiving a packet, we currently check the header. If it's no good, then we toss it out and continue the loop, leaving the caller waiting on that response. In cases where the packet has length inconsistencies, but the MID is valid, this leads to unneeded delays. That's especially problematic now that the client waits indefinitely for responses. Instead, don't immediately discard the packet if checkSMB fails. Try to find a matching mid_q_entry, mark it as having a malformed response and issue the callback.

2011-02-11tpm_tis: Use timeouts returned from TPMStefan Berger
The current TPM TIS driver in git discards the timeout values returned from the TPM. The check of the response packet needs to consider that the return_code field is 0 on success and the size of the expected packet is equivalent to the header size + u32 length indicator for the TPM_GetCapability() result + 3 timeout indicators of type u32. I am also adding a sysfs entry 'timeouts' showing the timeouts that are being used.

2011-02-10char/ipmi: fix OOPS caused by pnp_unregister_driver on unregistered driverCorey Minyard
This patch fixes an OOPS triggered when calling modprobe ipmi_si a second time after the first modprobe returned without finding any ipmi devices. This can happen if you reload the module after having the first module load fail. The driver was not deregistering from PNP in that case. Peter Huewe originally reported this patch and supplied a fix, I have a different patch based on Linus' suggestion that cleans things up a bit more.

2011-02-10cap_syslog: accept CAP_SYS_ADMIN for nowLinus Torvalds
In commit ce6ada35bdf7 ("security: Define CAP_SYSLOG") Serge Hallyn introduced CAP_SYSLOG, but broke backwards compatibility by no longer accepting CAP_SYS_ADMIN as an override (it would cause a warning and then reject the operation). Re-instate CAP_SYS_ADMIN - but keeping the warning - as an acceptable capability until any legacy applications have been updated. There are apparently applications out there that drop all capabilities except for CAP_SYS_ADMIN in order to access the syslog.

2011-02-10ALSA: hrtimer: remove superfluous tasklet invocationClemens Ladisch
Commit bb758e9637e5ddc removed snd_hrtimer_callback() from the hardware interrupt handler, thus moving it into a tasklet, but did not tell the ALSA timer framework about this, so the timer handling would now be done in the ALSA timer tasklet scheduled from another tasklet.

2011-02-10ALSA: hrtimer: handle delayed timer interruptsClemens Ladisch
If a timer interrupt was delayed too much, hrtimer_forward_now() will forward the timer expiry more than once. When this happens, the additional number of elapsed ALSA timer ticks must be passed to snd_timer_interrupt() to prevent the ALSA timer from falling behind. This mostly fixes MIDI slowdown problems on highly-loaded systems with badly behaved interrupt handlers.

2011-02-10perf tools: Fix thread_map event synthesizing in top and recordArnaldo Carvalho de Melo

So I investigated this and noticed that when we introduced support for recording a process and its threads using --pid some bugs were introduced and that the way to fix it was to instead of passing the target_tid to the event synthesizing routines we should better pass the thread_map that has the list of threads for a --pid or just the single thread for a --tid.

2011-02-09iwl3945: remove plcp checkStanislaw Gruszka
Patch fixes: https://bugzilla.redhat.com/show_bug.cgi?id=654599 Many users report very low speed problem on 3945 devices, this patch fixes problem, but only for some of them. For unknown reason, sometimes after hw scanning, device is not able to receive frames at high rate. Since plcp health check may request hw scan to "reset radio", performance problem start to be observable after update kernel to .35, where plcp check was introduced. Bug reporter confirmed that removing plcp check fixed problem for him.

2011-02-09ARM: Avoid building unsafe kernels on OMAP2 and MX3Russell King
OMAP2 (armv6) and MX3 turn off support for the V6K instructions, which when they include support for SMP kernels means that the resulting kernel is unsafe on SMP and can result in corrupted filesystems as we end up using unsafe bitops. Re-enable the use of V6K instructions on such kernels, and let such kernels running on V6 CPUs eat undefined instruction faults which will be much safer than filesystem corruption. Next merge window we can fix this properly (as it requires a much bigger set of changes.) Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2011-02-09KVM: SVM: Make sure KERNEL_GS_BASE is valid when loading gs_indexJoerg Roedel
The gs_index loading code uses the swapgs instruction to switch to the user gs_base temporarily. This is unsave in an lightweight exit-path in KVM on AMD because the KERNEL_GS_BASE MSR is switches lazily. An NMI happening in the critical path of load_gs_index may use the wrong GS_BASE value then leading to unpredictable behavior, e.g. a triple-fault. This patch fixes the issue by making sure that load_gs_index is called only with a valid KERNEL_GS_BASE value loaded in KVM.
