It fixes the FTRACE feature for parisc, which is horribly broken since quite some time and doesn't even compile. This patch just fixes the bare minimum (it actually removes more lines than it adds), so that the function tracer works again on 32- and 64bit kernels.

2016-04-14dm cache metadata: fix READ_LOCK macros and cleanup WRITE_LOCK macrosMike Snitzer
The READ_LOCK macro was incorrectly returning -EINVAL if dm_bm_is_read_only() was true -- it will always be true once the cache metadata transitions to read-only by dm_cache_metadata_set_read_only(). Wrap READ_LOCK and WRITE_LOCK multi-statement macros in do {} while(0). Also, all accesses of the 'cmd' argument passed to these related macros are now encapsulated in parenthesis. A follow-up patch can be developed to eliminate the use of macros in favor of pure C code. Avoiding that now given that this needs to apply to stable@.

2016-04-14/proc/iomem: only expose physical resource addresses to privileged usersLinus Torvalds
In commit c4004b02f8e5b ("x86: remove the kernel code/data/bss resources from /proc/iomem") I was hoping to remove the phyiscal kernel address data from /proc/iomem entirely, but that had to be reverted because some system programs actually use it. This limits all the detailed resource information to properly credentialed users instead. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2016-04-14pci-sysfs: use proper file capability helper functionLinus Torvalds
The PCI config access checked the file capabilities correctly, but used the itnernal security capability check rather than the helper function that is actually meant for that. The security_capable() has unusual return values and is not meant to be used elsewhere (the only other use is in the capability checking functions that we actually intend people to use, and this odd PCI usage really stood out when looking around the capability code.

2016-04-14Make file credentials available to the seqfile interfacesLinus Torvalds
A lot of seqfile users seem to be using things like %pK that uses the credentials of the current process, but that is actually completely wrong for filesystem interfaces. The unix semantics for permission checking files is to check permissions at _open_ time, not at read or write time, and that is not just a small detail: passing off stdin/stdout/stderr to a suid application and making the actual IO happen in privileged context is a classic exploit technique. So if we want to be able to look at permissions at read time, we need to use the file open credentials, not the current ones. Normal file accesses can just use "f_cred" (or any of the helper functions that do that, like file_ns_capable()), but the seqfile interfaces do not have any such options. It turns out that seq_file _does_ save away the user_ns information of the file, though. Since user_ns is just part of the full credential information, replace that special case with saving off the cred pointer instead, and suddenly seq_file has all the permission information it needs.

2016-04-14Revert "x86: remove the kernel code/data/bss resources from /proc/iomem"Linus Torvalds
This reverts commit c4004b02f8e5b9ce357a0bb1641756cc86962664. Sadly, my hope that nobody would actually use the special kernel entries in /proc/iomem were dashed by kexec. Which reads /proc/iomem explicitly to find the kernel base address. Nasty. Anyway, that means we can't do the sane and simple thing and just remove the entries, and we'll instead have to mask them out based on permissions.

2016-04-14pwm: fsl-ftm: Use flat regmap cacheStefan Agner
Use flat regmap cache to avoid lockdep warning at probe: [ 0.697285] WARNING: CPU: 0 PID: 1 at kernel/locking/lockdep.c:2755 lockdep_trace_alloc+0x15c/0x160() [ 0.697449] DEBUG_LOCKS_WARN_ON(irqs_disabled_flags(flags)) The RB-tree regmap cache needs to allocate new space on first writes. However, allocations in an atomic context (e.g. when a spinlock is held) are not allowed. The function regmap_write calls map->lock, which acquires a spinlock in the fast_io case. Since the pwm-fsl-ftm driver uses MMIO, the regmap bus of type regmap_mmio is being used which has fast_io set to true. The MMIO space of the pwm-fsl-ftm driver is reasonable condense, hence using the much faster flat regmap cache is anyway the better choice.

2016-04-13ALSA: hda - Fix inconsistent monitor_present state until repollTakashi Iwai
While the previous commit fixed the missing monitor_present flag update, it may be still in an inconsistent state while the driver repolls: the flag itself is updated, but the eld_valid flag and the contents don't follow until the repoll finishes (and may be repeated for a few times). The basic problem is that pin_eld->monitor_present is updated in the caller side. This should have been updated only in update_eld(). So, the proper fix is to avoid accessing pin_eld but only spec->temp_eld. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-04-13ALSA: hda - Fix regression of monitor_present flag in eld proc fileHyungwon Hwang
The commit [bd48128539ab: ALSA: hda - Fix forgotten HDMI monitor_present update] covered the missing update of monitor_present flag, but this caused a regression for devices without the i915 eld notifier. Since the old code supposed that pin_eld->monitor_present was updated by the caller side, the hdmi_present_sense_via_verbs() doesn't update the temporary eld->monitor_present but only pin_eld->monitor_present, which is now overridden in update_eld(). The fix is to update pin_eld->monitor_present as well before calling update_eld(). Note that this may still leave monitor_present flag in an inconsistent state when the driver repolls, but this is at least the old behavior. More proper fix will follow in the later patch.

2016-04-13drm/exynos: Use VIDEO_SAMSUNG_S5P_G2D=n as G2D Kconfig dependencyJavier Martinez Canillas
Commit 254d4d111ee1 ("drm/exynos: Add dependency for G2D in Kconfig") made the DRM_EXYNOS_G2D symbol to only be selectable if the s5p-g2d V4L2 driver is not enabled, since both use the same HW IP block. But added the dependency as depends on !VIDEO_SAMSUNG_S5P_G2D which isn't correct since Kconfig expressions are not boolean but tristate. So it will only evaluate to 'n' if VIDEO_SAMSUNG_S5P_G2D=y but it will evaluate to m if VIDEO_SAMSUNG_S5P_G2D=m. This means that both the V4L2 and DRM drivers can be enabled if the former is enabled as a module, which is not what we want.

2016-04-12drm/exynos: fimd: fix broken dp_clock controlMarek Szyprowski
Commit 1feafd3afd294b03dbbedb8e8f94e0c4db526f10 ("drm/exynos: add exynos5420 support for fimd") add support for Exynos 5420 SoC, but it broke enabling display clock feature because of incorrect condition check. This patch fixes it, so display is working again on platforms requiring display clock control (i.e. Exynos5250-based SNOW platform).

Fbdev code should be compiled only if CONFIG_DRM_FBDEV_EMULATION option is enabled.

2016-04-12drm/exynos: fix error handling in exynos_drm_subdrv_openArnd Bergmann
gcc-6 warns about a pointless loop in exynos_drm_subdrv_open: drivers/gpu/drm/exynos/exynos_drm_core.c: In function 'exynos_drm_subdrv_open': drivers/gpu/drm/exynos/exynos_drm_core.c:104:199: error: self-comparison always evaluates to false [-Werror=tautological-compare] list_for_each_entry_reverse(subdrv, &subdrv->list, list) { Here, the list_for_each_entry_reverse immediately terminates because the subdrv pointer is compared to itself as the loop end condition. If we were to take the current subdrv pointer as the start of the list (as we would do if list_for_each_entry_reverse() was not a macro), we would iterate backwards over the &exynos_drm_subdrv_list anchor, which would be even worse. Instead, we need to use list_for_each_entry_continue_reverse() to go back over each subdrv that was successfully opened until the first entry.

2016-04-12ALSA: usb-audio: Skip volume controls triggers hangup on Dell USB DockKailang Yang
This is Dell usb dock audio workaround. It was fixed the master volume keep lower. [Some background: the patch essentially skips the controls of a couple of FU volumes. Although the firmware exposes the dB and the value information via the usb descriptor, changing the values (we set the min volume as default) screws up the device. Although this has been fixed in the newer firmware, the devices are shipped with the old firmware, thus we need the workaround in the driver side. -- tiwai] Signed-off-by: Kailang Yang <kailang@realtek.com> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
