2011-01-11perf evsel: Fix order of event list deletionArnaldo Carvalho de Melo
We need to defer calling perf_evsel_list__delete() till after atexit registered routines, because we need to traverse the events being recorded at that time at least on 'perf record'. This fixes the problem reported by Thomas Renninger where cmd_record called by cmd_timechart would not write the tracing data to the perf.data file header because the evsel_list at atexit (control+C on 'perf timechart record') time would be empty, being already deleted by run_builtin(), and thus 'perf timechart' when trying to process such perf.data file would die with: "no trace data in the file" Problem introduced in 70d544d.

2011-01-11rtmutex: Fix comment about why new_owner can be NULL in wake_futex_pi()Steven Rostedt
The comment about why rt_mutex_next_owner() can return NULL in wake_futex_pi() is not the normal case. Tracing the cause of why this occurs is more likely that waiter simply timedout. But because it originally caused contention with the futex, the owner will go into the kernel when it unlocks the lock. Then it will hit this code path and rt_mutex_next_owner() will return NULL.

2011-01-11x86: Use PCI method for enabling AMD extended config space before MSR methodJan Beulich
While both methods should work equivalently well for the native case, the Xen Dom0 case can't reliably work with the MSR one, since there's no guarantee that the virtual CPUs it has available fully cover all necessary physical ones. As per the suggestion of Robert Richter the patch only adds the PCI method, but leaves the MSR one as a fallback to cover new systems the PCI IDs of which may not have got added to the code base yet. The only change in v2 is the breaking out of the new CPI initialization method into a separate function, as requested by Ingo.

2011-01-11sh: Fix up legacy PTEA space attribute mapping.Paul Mundt
When p3_ioremap() was converted to ioremap_prot() there was some breakage introduced where the 29-bit segmentation logic would trap the area range and return an identity mapping without having allowed the area specification to force mapping through page tables. This wires up a PCC mask for pgprot verification to work out whether to short-circuit the identity mapping on legacy parts, restoring the previous behaviour.

2011-01-11powerpc/pseries: Fix VPHN build errors on non-SMP systemsJesse Larrew
The header asm/hvcall.h was previously included indirectly via smp.h. On non-SMP systems, however, these declarations are excluded and the build breaks. This is easily fixed by including asm/hvcall.h directly. The VPHN feature is only meaningful on NUMA systems that implement the SPLPAR option, so exclude the VPHN code on systems without SPLPAR enabled. Also, expose unmap_cpu_from_node() on systems with SPLPAR enabled, even if CONFIG_HOTPLUG_CPU is disabled. Lastly, map_cpu_to_node() is now needed by VPHN to manipulate the node masks after boot time, so remove the __cpuinit annotation to fix a section mismatch.

2011-01-10Merge branch 'master' into for-linus-mergedAlex Elder
This merge pulls the XFS master branch into the latest Linus master. This results in a merge conflict whose best fix is not obvious. I manually fixed the conflict, in "fs/xfs/xfs_iget.c". Dave Chinner had done work that resulted in RCU freeing of inodes separate from what Nick Piggin had done, and their results differed slightly in xfs_inode_free(). The fix updates Nick's call_rcu() with the use of VFS_I(), while incorporating needed updates to some XFS inode fields implemented in Dave's series. Dave's RCU callback function has also been removed. Signed-off-by: Alex Elder <aelder@sgi.com>

Configuring the kernel I found that the Matrox frame buffer help has a different option than the one in the docs (Documentation/fb/matroxfb.txt). I decided to check the source code to see what is the correct option. drivers/video/matrox/matroxfb_base.c has a lot of comments that sugests that the video option is "matrox". However in line 2452 of this same file you have: fb_get_options("matroxfb", &option) video=matroxfb:XXX is the correct video option not video=matrox:XXX.

2011-01-11fbdev: sh_mobile_hdmi: add command line option to use the preferred EDID modeGuennadi Liakhovetski
Currently, if no command-line option is specified, the sh_mobile_hdmi will use the default 720p video mode. If a command line option of the form "video=sh_mobile_lcdc:<width>x<height>@<refresh>" is provided, the driver will look for that mode among those, available in the monitor EDID. This patch adds the ability to request the driver to use monitor's preferred mode by specifying 0 as width and hight in the above string. If that mode is not supported by the system, the driver will continue scanning through EDID modes, until it finds a suitable one.

Currently on receipt of a response message (ACKs, RDMA Response, Atomic Responses etc.) if the SDMA completion counter is not advanced the driver delays the completion of the WQE. In most cases this is overly pessimistic as the response (ACK) to a previously transmitted send implies that the send is complete.
