Commit 717f3bbab3c7628736ef738fdbf3d9a28578c26c, 'serial_core: Fix conditional start_tx on ring buffer not empty' exposes an incorrect assumption in several drivers' start_tx methods; the tx ring buffer can, in fact, be empty when restarting tx while performing flow control. Affected drivers: sunsab.c ip22zilog.c pmac_zilog.c sunzilog.c m32r_sio.c imx.c Other in-tree serial drivers either are not affected or already test for empty tx ring buffer before transmitting. Test for empty tx ring buffer in start_tx() method, after transmitting x_char (if applicable). Reported-by: Aaro Koskinen <[email protected]> Cc: Seth Bollinger <[email protected]> Cc: "David S.

2014-07-11ARM: EXYNOS: Register cpuidle device only on exynos4210 and 5250Tomasz Figa1-4/+2
Currently, the exynos cpuidle driver works correctly only on exynos4210 and 5250. Trying to use it with just one CPU online on any other exynos SoCs will lead to system failure, due to unsupported AFTR mode on other SoCs. This patch fixes the problem by registering the driver only on supported SoCs and letting others simply use default WFI mode until support for them is added.

2014-07-10x86-32, vdso: Fix vDSO build error due to missing align_vdso_addr()Jan Beulich1-0/+4
Relying on static functions used just once to get inlined (and subsequently have dead code paths eliminated) is wrong: Compilers are free to decide whether they do this, regardless of optimization level. With this not happening for vdso_addr() (observed with gcc 4.1.x), an unresolved reference to align_vdso_addr() causes the build to fail. [ hpa: vdso_addr() is never actually used on x86-32, as calculate_addr in map_vdso() is always false. It ought to be possible to clean this up further, but this fixes the immediate problem. ] Signed-off-by: Jan Beulich <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Acked-by: Andy Lutomirski <[email protected]> Tested-by: Boris Ostrovsky <[email protected]> Tested-by: Andrew Morton <[email protected]> Signed-off-by: H.

2014-07-11ARM: EXYNOS: Add support for clock handling in power domainPrathyush K2-1/+80
While powering on/off a local powerdomain in exynos5 chipsets, the input clocks to each device gets modified. This behaviour is based on the SYSCLK_SYS_PWR_REG registers. E.g. SYSCLK_MFC_SYS_PWR_REG = 0x0, the parent of input clock to MFC (aclk333) gets modified to oscclk = 0x1, no change in clocks. The recommended value of SYSCLK_SYS_PWR_REG before power gating any domain is 0x0. So we must also restore the clocks while powering on a domain everytime. This patch adds the framework for getting the required mux and parent clocks through a power domain device node. With this patch, while powering off a domain, parent is set to oscclk and while powering back on, its re-set to the correct parent which is as per the recommended pd on/off sequence.

2014-07-10dm mpath: fix IO hang due to logic bug in multipath_busyJun'ichi Nomura1-2/+3
Commit e80991773 ("dm mpath: push back requests instead of queueing") modified multipath_busy() to return true if !pg_ready(). pg_ready() checks the current state of the multipath device and may return false even if a new IO is needed to change the state. Bart Van Assche reported that he had multipath IO lockup when he was performing cable pull tests. Analysis showed that the multipath device had a single path group with both paths active, but that the path group itself was not active. During the multipath device state transitions 'queue_io' got set but nothing could clear it. Clearing 'queue_io' only happens in __choose_pgpath(), but it won't be called if multipath_busy() returns true due to pg_ready() returning false when 'queue_io' is set. As such the !pg_ready() check in multipath_busy() is wrong because new IO will not be sent to multipath target and the multipath state change won't happen. That results in multipath IO lockup. The intent of multipath_busy() is to avoid unnecessary cycles of dequeue + request_fn + requeue if it is known that the multipath device will requeue. Such "busy" situations would be: - path group is being activated - there is no path and the multipath is setup to requeue if no path Fix multipath_busy() to return "busy" early only for these specific situations.

There's a race condition between the atomic_dec_and_test(&io->count) in dec_count() and the waking of the sync_io() thread. If the thread is spuriously woken immediately after the decrement it may exit, making the on stack io struct invalid, yet the dec_count could still be using it.

2014-07-10dm: allocate a special workqueue for deferred device removalMikulas Patocka1-2/+13
The commit 2c140a246dc ("dm: allow remove to be deferred") introduced a deferred removal feature for the device mapper. When this feature is used (by passing a flag DM_DEFERRED_REMOVE to DM_DEV_REMOVE_CMD ioctl) and the user tries to remove a device that is currently in use, the device will be removed automatically in the future when the last user closes it. Device mapper used the system workqueue to perform deferred removals. However, some targets (dm-raid1, dm-mpath, dm-stripe) flush work items scheduled for the system workqueue from their destructor. If the destructor itself is called from the system workqueue during deferred removal, it introduces a possible deadlock - the workqueue tries to flush itself. Fix this possible deadlock by introducing a new workqueue for deferred removals. We allocate just one workqueue for all dm targets. The ability of dm targets to process IOs isn't dependent on deferred removal of unused targets, so a deadlock due to shared workqueue isn't possible. Also, cleanup local_init() to eliminate potential for returning success on failure.

This patch fixes an issue that the renesas_usbhs driver in gadget mode cannot work correctly even if I disabled DMAC of the driver when I used the g_zero driver and the testusb tool. When a usb cable is re-connected, the renesas_usbhs driver calls the usbhsp_flags_init() (via usbhs_hotplug() --> usbhs_mod_call(start) --> usbhsg_try_start() --> usbhs_pipe_init()). However, the driver doesn't call the usbhsp_flags_init() when usbhsg_ep_disable() is called. So, if a gadget driver calls usb_ep_enable() and usb_ep_disable() again and again, the renesas_usbhs driver will output the following log: renesas_usbhs renesas_usbhs: can't get pipe (BULK) renesas_usbhs renesas_usbhs: wrong recip request Acked-by: Kuninori Morimoto <[email protected]> Signed-off-by: Yoshihiro Shimoda <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>

2014-07-10m68k: Fix boot regression on machines with RAM at non-zeroGeert Uytterhoeven1-1/+2
My enhancement to store the initial mapping size for later reuse in commit 486df8bc4627bdfc032d11bedcd056cc5343ee62 ("m68k: Increase initial mapping to 8 or 16 MiB if possible") broke booting on machines where RAM doesn't start at address zero. Use pc-relative addressing to fix this. Reported-by: Andreas Schwab <[email protected]> Signed-off-by: Geert Uytterhoeven <[email protected]> Tested-by: Andreas Schwab <[email protected]>

git://anongit.freedesktop.org/drm-intel into drm-fixes Fixes for regressions and black screens, cc: stable where applicapable (the last minute rebase was to sprinkle missing stable tags). A bit more than what I'd wish for, but excluding vlv and that the first 3 patches are just quirks for 1 regression it looks much better. There's still a "oops, lost dithering" issue on older platforms open. I'm working on a fix for that now but didn't want to delay this pile. * tag 'drm-intel-fixes-2014-07-09' of git://anongit.freedesktop.org/drm-intel: drm/i915/vlv: T12 eDP panel timing enforcement during reboot drm/i915: Only unbind vgacon, not other console drivers drm/i915: Don't clobber the GTT when it's within stolen memory drm/i915/vlv: Update the DSI ULPS entry/exit sequence drm/i915/vlv: DPI FIFO empty check is not needed drm/i915: Toshiba CB35 has a controllable backlight drm/i915: Acer C720 and C720P have controllable backlights drm/i915: quirk asserts controllable backlight presence, overriding VBT

2014-07-09i8k: Fix non-SMP operationGuenter Roeck1-1/+3
Commit f36fdb9f0266 (i8k: Force SMM to run on CPU 0) adds support for multi-core CPUs to the driver. Unfortunately, that causes it to fail loading if compiled without SMP support, at least on 32 bit kernels. Kernel log shows "i8k: unable to get SMM Dell signature", and function i8k_smm is found to return -EINVAL. Testing revealed that the culprit is the missing return value check of set_cpus_allowed_ptr.
