2011-10-14perf ui browser: Add filter methodArnaldo Carvalho de Melo
Its becoming common to allow the user to filter out parts of the data structure being browsed, like already done in the hists browser and in the annotate browser in the next commit, so provide it directly in the ui_browser class list_head helpers. More work required to move the equivalent routines found now in the hists browser to the rb_tree helpers.

2011-10-14perf hists browser: Invalidate ui_browser->top after timer callsArnaldo Carvalho de Melo
With underlying dynamic data structures we need to invalidate pointers to them after a timer, as that entry may have vanished (decayed in top, for instance). I forgot about browser_ui->top. Fix it by resetting it to null after a timer. The seek operation from SEEK_SET will then set it to a valid entry because it starts from rb_first(&hists->entries).

2011-10-14tracing: Fix returning of duplicate data after EOF in trace_pipe_rawSteven Rostedt
The trace_pipe_raw handler holds a cached page from the time the file is opened to the time it is closed. The cached page is used to handle the case of the user space buffer being smaller than what was read from the ring buffer. The left over buffer is held in the cache so that the next read will continue where the data left off. After EOF is returned (no more data in the buffer), the index of the cached page is set to zero. If a user app reads the page again after EOF, the check in the buffer will see that the cached page is less than page size and will return the cached page again. This will cause reading the trace_pipe_raw again after EOF to return duplicate data, making the output look like the time went backwards but instead data is just repeated. The fix is to not reset the index right after all data is read from the cache, but to reset it after all data is read and more data exists in the ring buffer.

2011-10-14xenbus: don't rely on xen_initial_domain to detect local xenstoreDaniel De Graaf
The xenstore daemon does not have to run in the xen initial domain; however, Linux currently uses xen_initial_domain to test if a loopback event channel should be used instead of the event channel provided in Xen's start_info structure. Instead, if the event channel passed in the start_info structure is not valid, assume that this domain will run xenstored locally and set up the event channel.

2011-10-14x86, intel: Output microcode revision in /proc/cpuinfoAndi Kleen
I got a request to make it easier to determine the microcode update level on Intel CPUs. This patch adds a new "microcode" field to /proc/cpuinfo. The microcode level is also outputed on fatal machine checks together with the other CPUID model information. I removed the respective code from the microcode update driver, it just reads the field from cpu_data. Also when the microcode is updated it fills in the new values too. I had to add a memory barrier to native_cpuid to prevent it being optimized away when the result is not used. This turns out to clean up further code which already got this information manually. This is done in followon patches. Signed-off-by: Andi Kleen <ak@linux.intel.com> Acked-by: H.

2011-10-14microblaze: Remove __ARCH_WANT_INTERRUPTS_ON_CTXSW usagePeter Zijlstra
As far as I can tell the only reason microblaze has __ARCH_WANT_INTERRUPTS_ON_CTXSW is because it initializes new task state with interrupts enabled so that on switch_to() interrupts get enabled. So change copy_thread() to clear MSR_IE instead of set it, this will ensure switch_to() will always keep IRQs disabled. The scheduler will disable IRQs when taking rq->lock in schedule() and enable IRQs in finish_lock_switch() after its done its magic. This leaves ARM the only __ARCH_WANT_INTERRUPTS_ON_CTXSW user.

Since commit af337f3e633a198034a99450416257ddf2307497 "ARM: S3C2443: Move parts of the clock code to common clock file", the init_clocks array is moved to arch/arm/plat-s3c24xx/s3c2443-clock.c. Now we call s3c_register_clocks for init_clocks in s3c2443_common_init_clocks. Thus we can remove the empty init_clocks array here and remove the redundant s3c_register_clocks call for init_clocks in s3c2443_init_clocks.

S3C2443 uses hsmmc1 as its only hsmmc device and for S3C2416/S3C2450 it's the second hsmmc channel with the same PCLKCON bit.

So to make it possible to identify the hsmmc1 pclk on S3C2416 add the correct devname for it. The sclk name on S3C2443 also is s3c-sdhci.1.
