The currently perf diff didn't add the baseline and delta (or other compute) fields to the sort list so output will be sorted by other fields like alphabetical order of DSO or symbol as below example.

Fix to fall back to find a probe point in symbols if perf fails to find it in debuginfo. This can happen when the target function is an alias of another function. Such alias doesn't have an entry in debuginfo but in symbols. David Ahern reported this problem in https://lkml.org/lkml/2014/12/29/355 I ensured the problem and deeper investigation discovers it. ----- eu-readelf --debug-dump=info /usr/lib/debug/lib/x86_64-linux-gnu/libc-2.19.so | grep \"malloc\" -A6 name (strp) "malloc" decl_file (data1) 25 decl_line (data2) 466 prototyped (flag_present) type (ref4) [ 81b5] declaration (flag_present) [ 8f58] formal_parameter -- name (strp) "malloc" decl_file (data1) 23 decl_line (data2) 466 prototyped (flag_present) type (ref4) [ 9f4a] declaration (flag_present) sibling (ref4) [ bb29] ... ----- All these entires have no instances (all of them are declarations) This is why the perf probe failed to find it in debuginfo. However, there are some malloc instances in symbols. ----- eu-readelf --symbols /usr/lib/debug/lib/x86_64-linux-gnu/libc-2.19.so | grep malloc$ 1181: 0000000000080700 5332 FUNC LOCAL DEFAULT 12 _int_malloc 4537: 00000000000831d0 339 FUNC LOCAL DEFAULT 12 __GI___libc_malloc 5545: 00000000000831d0 339 FUNC LOCAL DEFAULT 12 __malloc 6063: 00000000000831d0 339 FUNC GLOBAL DEFAULT 12 malloc 7302: 00000000000831d0 339 FUNC GLOBAL DEFAULT 12 __libc_malloc ----- As you an see, malloc and __libc_malloc have same address, and actually __libc_malloc has an entry in debuginfo. So you can set up a probe on __libc_malloc. To fix this problem shortly, perf probe simply falls back to find probe point(malloc) in symbols if it is not found in debuginfo. Reported-by:

Follow aa0d5326 ("ia64: Use preempt_schedule_irq") and use preempt_schedule_irq instead of enabling/disabling interrupts and messing around with PREEMPT_ACTIVE in the nios2 low-level preemption code ourselves. Also get rid of the now needless re-check for TIF_NEED_RESCHED, preempt_schedule_irq will already take care of rescheduling.

This reverts commit 24a0aa21 . It's causing severe userspace breakage. Namely, all the utilities from wireless-utils which are relying on CONFIG_WEXT (which means tools like 'iwconfig', 'iwlist', etc) are not working anymore. There is a 'iw' utility in newer wireless-tools, which is supposed to be a replacement for all the "deprecated" binaries, but it's far away from being massively adopted. Please see [1] for example of the userspace breakage this is causing. In addition to that, Larry Finger reports [2] that this patch is also causing ipw2200 driver being impossible to build. To me this clearly shows that CONFIG_WEXT is far, far away from being "deprecated enough" to be removed.

Currently we enable Exynos devices in the multi v7 defconfig, however, when testing on my ODROID-U3, I noticed that USB was not working. Enabling this option causes USB to work, which enables networking support as well since the ODROID-U3 has networking on the USB bus. [arnd] Support for odroid-u3 was added in 3.10, so it would be nice to backport this fix at least that far. Signed-off-by:

Unfortunately, while commit 4a928436 ("audit: correctly record file names with different path name types") fixed a problem where we were not recording filenames, it created a new problem by attempting to use these file names after they had been freed. This patch resolves the issue by creating a copy of the filename which the audit subsystem frees after it is done with the string. At some point it would be nice to resolve this issue with refcounts, or something similar, instead of having to allocate/copy strings, but that is almost surely beyond the scope of a -rcX patch so we'll defer that for later. On the plus side, only audit users should be impacted by the string copying. Reported-by:

However, the SDI driver doesn't set the port number, which causes the SDI display to not initialize. Fix this by setting the SDI port number to 1. We use a hardcoded value, as SDI was used only on OMAP3 and it's always port number 1 there. Reported-by:

Pull thermal management updates from Zhang Rui: "First of all, the most important change is the thermal cpu cooling fixes. The major fix here is to have proper sequencing between cpufreq layer and thermal cpu cooling registration. A take away of this fix is an improvement in the thermal drivers code. Thermal drivers that require cpu cooling do not need to check for cpufreq layer. The requirement now is to propagate the error code, if any, while registering cpu cooling device. Thanks to Viresh for implementing the required CPUfreq changes. Second, a new driver is introduced for int340x processor thermal device. Given that int340x thermal is disabled by default, and this processor thermal device is only available on limited platforms, plus the driver does nothing but exposes some thermal limitation information for user space to use, thus I think it is safe to include it in this pull request after missing 3.19-rc2.

Commit 2457aec6 ("mm: non-atomically mark page accessed during page cache allocation where possible") has added a separate parameter for specifying gfp mask for radix tree allocations. Not only this is less than optimal from the API point of view because it is error prone, it is also buggy currently because grab_cache_page_write_begin is using GFP_KERNEL for radix tree and if fgp_flags doesn't contain FGP_NOFS (mostly controlled by fs by AOP_FLAG_NOFS flag) but the mapping_gfp_mask has __GFP_FS cleared then the radix tree allocation wouldn't obey the restriction and might recurse into filesystem and cause deadlocks. This is the case for most filesystems unfortunately because only ext4 and gfs2 are using AOP_FLAG_NOFS. Let's simply remove radix_gfp_mask parameter because the allocation context is same for both page cache and for the radix tree. Just make sure that the radix tree gets only the sane subset of the mask (e.g. do not pass __GFP_WRITE). Long term it is more preferable to convert remaining users of AOP_FLAG_NOFS to use mapping_gfp_mask instead and simplify this interface even further. Reported-by:

If the probe of an fb driver has been deferred due to missing dependencies, and the probe is later ran when a module is loaded, the fbdev framework will try to find a logo to use. However, the logos are __initdata, and have already been freed. This causes sometimes page faults, if the logo memory is not mapped, sometimes other random crashes as the logo data is invalid, and sometimes nothing, if the fbdev decides to reject the logo (e.g. the random value depicting the logo's height is too big). This patch adds a late_initcall function to mark the logos as freed. In reality the logos are freed later, and fbdev probe may be ran between this late_initcall and the freeing of the logos. In that case we will miss drawing the logo, even if it would be possible. Signed-off-by:
