commit 6d91f2c0 upstream. This patch selects QCOM_GDSC Kconfig for msm8996 GCC and MMCC clock controllers, as these provide some of the gdscs on the SOC. Also selecting this config will make it align with other drivers which do the same. Signed-off-by:

commit 67615c58 upstream. If the firmware had set up a clock to source from PLLC, go along with it. But if we're looking for a new parent, we don't want to switch it to PLLC because the firmware will force PLLC (and thus the AXI bus clock) to different frequencies during over-temp/under-voltage, without notification to Linux. On my system, this moves the Linux-enabled HDMI state machine and DSI1 escape clock over to plld_per from pllc_per. EMMC still ends up on pllc_per, because the firmware had set it up to use that.

commit 6cd997db upstream. con3270 contains an optimisation that reduces the amount of data to be transmitted to the 3270 terminal by putting a Repeat to Address (RA) order into the data stream. The RA order itself takes up space, so con3270 only uses it if there's enough space left in the line buffer. Otherwise it just pads out the line manually. For lines that were _just_ short enough that the RA order still fit in the line buffer, the line was instead padded with an insufficient amount of spaces. This was caused by examining the size of the allocated line buffer rather than the length of the string to be displayed. For con3270_cline_end(), we just compare against the line length. For con3270_update_string() however that isn't available anymore, so we check whether the Repeat to Address order is present. Fixes: f51320a5 ("[PATCH] s390: new 3270 driver.")

commit c14f2aac upstream. con3270 contains an optimisation that reduces the amount of data to be transmitted to the 3270 terminal by putting a Repeat to Address (RA) order into the data stream. The RA order itself takes up space, so con3270 only uses it if there's enough space left in the line buffer. Otherwise it just pads out the line manually. For lines too long to include the RA order, one byte was left uninitialised. This was caused by an off-by-one bug in the loop that pads out the line. Since the buffer is allocated from a common pool, the single byte left uninitialised contained some previous buffer content. Usually this was just a space or some character (which can result in clutter but is otherwise harmless). Sometimes, however, it was a Repeat to Address order, messing up the entire screen layout and causing the display to send the entire buffer content on every keystroke.

commit d53c51f2 upstream. Since commit 9f3d6d7a chsc_get_channel_measurement_chars is called with interrupts disabled during resume from hibernate. Since this function used spin_unlock_irq, interrupts have been enabled accidentally. Fix this by using the irqsave variant. Since we can't guarantee the IRQ-enablement state for all (future/ external) callers, change the locking in related functions to prevent similar bugs in the future.

commit a1944030 upstream. When a view destruction command was present in the command stream, the view was validated to avoid a device error. That caused excessive and unnecessary validations of views, surfaces and mobs on view destruction. Replace this with a new relocation type that patches the view destruction command to a NOP if the view is not present in the device after the execbuf validation sequence. Also add checks for the member size of the vmw_res_relocation struct. Fixes sporadic command submission errors on google-earth exit. Reported-by:

commit eb03aa00 upstream. For every pfn aligned to minimum_order, dissolve_free_huge_pages() will call dissolve_free_huge_page() which takes the hugetlb spinlock, even if the page is not huge at all or a hugepage that is in-use. Improve this by doing the PageHuge() and page_count() checks already in dissolve_free_huge_pages() before calling dissolve_free_huge_page(). In dissolve_free_huge_page(), when holding the spinlock, those checks need to be revalidated. Link: http://lkml.kernel.org/r/20160926172811.94033-4-gerald.schaefer@de.ibm.comSigned-off-by:

commit 082d5b6b upstream. In dissolve_free_huge_pages(), free hugepages will be dissolved without making sure that there are enough of them left to satisfy hugepage reservations. Fix this by adding a return value to dissolve_free_huge_pages() and checking h->free_huge_pages vs. h->resv_huge_pages. Note that this may lead to the situation where dissolve_free_huge_page() returns an error and all free hugepages that were dissolved before that error are lost, while the memory block still cannot be set offline.

commit 86c7e683 upstream. A workaround for a warning introduced a use of the NO_IRQ macro that should have been gone for a long time. It is clear from the code that the value cannot actually be used, but apparently there was a configuration at some point that caused a warning, so instead of just reverting that patch, this rearranges the code in a way that the warning cannot reappear.

commit a3930ed0 upstream. Commit d88429a6 ("ASoC: dapm: Add output driver widget") added the snd_soc_dapm_out_drv ID for the output driver widget, which is the same as the PGA widget, with a later power sequence number. Commit 19a2557b ("ASoC: dapm: Add kcontrol support for PGAs") then added kcontrol support for PGA widgets, but failed to account for output driver widgets. Attempts to use kcontrols with output driver widgets result in silent failures, with the developer having little idea about what went on. Add snd_soc_dapm_out_drv to the switch/case block under snd_soc_dapm_pga in dapm_create_or_share_kcontrol, since they are essentially the same.

commit 09951d83 upstream. So far, sub part of mv_cesa_int was responsible of dequeuing complete requests, then call the 'cleanup' operation on these reqs and call the crypto api callback 'complete'. The problem is that the transformation context 'ctx' is retrieved only once before the while loop. Which means that the wrong 'cleanup' operation might be called on the wrong type of cesa requests, it can lead to memory corruptions with this message: marvell-cesa f1090000.crypto: dma_pool_free cesa_padding, 5a5a5a5a/5a5a5a5a (bad dma) This commit fixes the issue, by updating the transformation context for each dequeued cesa request.

commit 18f53fe0 upstream. commit 7a0adc83 ("ath10k: improve tx scheduling") is causing severe throughput drop in multi client mode. This issue is originally reported in veriwave setup with 50 clients with TCP downlink traffic. While increasing number of clients, the average throughput drops gradually. With 50 clients, the combined peak throughput is decreased to 98 Mbps whereas reverting given commit restored it to 550 Mbps. Processing txqs for every tx completion is causing overhead. Ideally for management frame tx completion, pending txqs processing can be avoided. The change partly reverts the commit "ath10k: improve tx scheduling". Processing pending txqs after all skbs tx completion will yeild enough room to burst tx frames. Fixes: 7a0adc83 ("ath10k: improve tx scheduling") Signed-off-by:

commit e4fd726f upstream. In the wake tx queue path, we are not checking if the frame to be sent takes management path or not. For eg. QOS null func frame coming here will take the management path. Since we are not incrementing the descriptor counter (num_pending_mgmt_tx) w.r.t tx management, on tx completion it is possible to see negative values. When the above counter reaches a negative value, we will not be sending a probe response out. if (is_presp && ar->hw_params.max_probe_resp_desc_thres < htt->num_pending_mgmt_tx) For IPQ4019, max_probe_resp_desc_thres (u32) is 24 is compared against num_pending_mgmt_tx (int) and the above condtions comes true if the counter is negative and we drop the probe response. To avoid this, check on the wake tx queue path as well for the tx path of the frame and increment the appropriate counters Fixes: cac08552 "ath10k: move mgmt descriptor limit handle under mgmt_tx" Signed-off-by:
