Commit 01c9348c7620ec65

powerpc: Use hardware RNG for arch_get_random_seed_* not arch_get_random_*

updated arch_get_random_[int|long]() to be NOPs, and moved the hardware RNG backing to arch_get_random_seed_[int|long]() instead. However, it failed to take into account that arch_get_random_int() was implemented in terms of arch_get_random_long(), and so we ended up with a version of the former that is essentially a NOP as well.

Fix this by calling arch_get_random_seed_long() from arch_get_random_seed_int() instead.

Removing the drm_bridge_remove call should avoid a NULL dereference during list processing in drm_bridge_remove if the error path is ever taken.

The more natural approach would perhaps be to add a drm_bridge_add, but there are several other bridges that never call drm_bridge_add. Just removing the drm_bridge_remove is the easier fix.

A quirk in snd-usb-audio was added to automate setting sample rate to 4800k and remove the previously exposed nonfunctional microphone for the Bowers & Wilkins PX: commit 240a8af929c7c57dcde28682725b29cf8474e8e5 https://lore.kernel.org/patchwork/patch/919689/

However the headphones where updated shortly after that to remove the unintentional microphone functionality. I guess because of this the headphones now crash when connecting them via USB while the quirk is active. Dmesg:

snd-usb-audio: probe of 2-3:1.0 failed with error -22 usb 2-3: 2:1: cannot get min/max values for control 2 (id 2)

This patch removes the microfone and allows the headphones to connect and work out of the box. It is based on the current mainline kernel and successfully applied an tested on my machine (4.18.10.arch1-1).

[ Upstream commit c54c7374ff44de5e609506aca7c0deae4703b6d1 ]

Jerry Zuo pointed out a rather obscure hotplugging issue that it seems I accidentally introduced into DRM two years ago.

Pretend we have a topology like this:

|- DP-1: mst_primary |- DP-4: active display |- DP-5: disconnected |- DP-6: active hub |- DP-7: active display |- DP-8: disconnected |- DP-9: disconnected

If we unplug DP-6, the topology starting at DP-7 will be destroyed but it's payloads will live on in DP-1's VCPI allocations and thus require removal. However, this removal currently fails because drm_dp_update_payload_part1() will (rightly so) try to validate the port before accessing it, fail then abort. If we keep going, eventually we run the MST hub out of bandwidth and all new allocations will start to fail (or in my case; all new displays just start flickering a ton).

We could just teach drm_dp_update_payload_part1() not to drop the port ref in this case, but then we also need to teach drm_dp_destroy_payload_step1() to do the same thing, then hope no one ever adds anything to the that requires a validated port reference in drm_dp_destroy_connector_work(). Kind of sketchy.

So let's go with a more clever solution: any port that drm_dp_destroy_connector_work() interacts with is guaranteed to still exist in memory until we say so. While said port might not be valid we don't really care: that's the whole reason we're destroying it in the first place! So, teach drm_dp_get_validated_port_ref() to use the all mighty current_work() function to avoid attempting to validate ports from the context of mgr->destroy_connector_work. I can't see any situation where this wouldn't be safe, and this avoids having to play whack-a-mole in the future of trying to work around port validation.

ib_dma_map_sg() augments the SGL into a 'dma mapped SGL'. This process may change the number of entries and the lengths of each entry.

Code that touches dma_address is iterating over the 'dma mapped SGL' and must use dma_nents which returned from ib_dma_map_sg().

ib_sg_to_pages() and ib_map_mr_sg() are using dma_address so they must use dma_nents.

[ Upstream commit dc9e47160626cdb58d5c39a4f43dcfdb27a5c004 ]

Shifting a u8 by 24 will cause the value to be promoted to an integer. If the top bit of the u8 is set then the following conversion to an unsigned long will sign extend the value causing the upper 32 bits to be set in the result.

Fix this by casting the u8 value to an unsigned long before the shift.

Using dma_dev->dev for mappings before it's assigned with the correct device is unlikely to work as expected, and with future dma-direct changes, passing a NULL device may end up crashing entirely. I don't know enough about this hardware or the mv_xor_prep_dma_interrupt() operation to implement the appropriate error-handling logic that would have revealed those dma_map_single() calls failing on arm64 for as long as the driver has been enabled there, but moving the assignment earlier will at least make the current code operate as intended.

Fix a soft lockup when NFS client delegation recovery is attempted but the inode is in the process of being freed. When the igrab(inode) call fails, and we have to restart the recovery process, we need to ensure that we won't attempt to recover the same delegation again.

[ Upstream commit ca70ea43f80c98582f5ffbbd1e6f4da2742da0c4 ]

MCPM does a soft reset of the CPUs and uses common cpu_resume() routine to perform low-level platform initialization. This results in a try to install HYP stubs for the second time for each CPU and results in false HYP/SVC mode mismatch detection. The HYP stubs are already installed at the beginning of the kernel initialization on the boot CPU (head.S) or in the secondary_startup() for other CPUs. To fix this issue MCPM code should use a cpu_resume() routine without HYP stubs installation.

This change fixes HYP/SVC mode mismatch on Samsung Exynos5422-based Odroid XU3/XU4/HC1 boards.

megaraid_sas takes 1+ seconds to load while waiting for firmware:

[2.822603] megaraid_sas 0000:03:00.0: Waiting for FW to come to ready state [3.871003] megaraid_sas 0000:03:00.0: FW now in Ready state

This is due to the following loop in megasas_transition_to_ready(), which waits a minimum of 1 second, even though the FW becomes ready in tens of millisecs:

/* * The cur_state should not last for more than max_wait secs */ for (i = 0; i < max_wait; i++) { ... msleep(1000); ... dev_info(&instance->pdev->dev, "FW now in Ready state\n");

This is a regression, caused by a change of the msleep granularity from 1 to 1000 due to concern about waiting too long on systems with coarse jiffies.

To fix, increase iterations and use msleep(20), which results in:

We fix this by initializing 'maddr' to NULL. For the matter of clarity, we also test if 'xmitq' is non-empty before we use it and 'maddr' further down in the function. It will never happen that 'xmitq' is non- empty at the same time as 'maddr' is NULL, so this is a sufficient test.

Commit 747834ab8347 ("ARM: OMAP2+: hwmod: revise hardreset behavior") made the call to _enable() conditional based on no oh->rst_lines_cnt. This caused the return value to be potentially uninitialized. Curiously we see no compiler warnings for this, probably as this gets inlined.

We call _setup_reset() from _setup() and only _setup_postsetup() if the return value is zero. Currently the return value can be uninitialized for cases where oh->rst_lines_cnt is set and HWMOD_INIT_NO_RESET is not set.

[ Upstream commit 1a89ac5b91895127f7c586ec5075c3753ca25501 ]

Fixes: computation of actual bytes to fill/receive in/from FIFO in unpacked mode when transfer length is not a multiple of requested bits per word.

unpacked mode transfers fails when the transfer includes partial bytes in the last word.

Total words to be written/read to/from FIFO is computed based on transfer length and bits per word. Unpacked mode includes 0 padding bytes for partial words to align with bits per word and these extra bytes are also accounted for calculating bytes left to transfer in the current driver.

This causes extra bytes access of tx/rx buffers along with buffer index position crossing actual length where remain_len becomes negative and due to unsigned type, negative value is a 32 bit representation of signed value and transferred bytes never meets the actual transfer length resulting in transfer timeout and a hang.

This patch fixes this with proper computation of the actual bytes to fill in FIFO during transmit and the actual bytes to read from FIFO during receive ignoring 0 padded bytes.

[ Upstream commit 509c583620e9053e43d611bf1614fc3d3abafa96 ]

The original driver by default defines num_chipselects as -1. This actually allicates an array of 65535 entries in of_spi_register_master.

There is a side-effect for buggy device trees that (contrary to dt-binding documentation) have no cs-gpio defined.

This mode was never supported by the driver due to limitations of native cs and additional code complexity and is explicitly not stated to be implemented.

To keep backwards compatibility with such buggy DTs we limit the number of chip_selects to 1, as for all practical purposes it is only ever realistic to use a single chip select in native cs mode without negative side-effects.

Super-IO accesses may fail on a system with no or unmapped LPC bus.

Also, other drivers may attempt to access the LPC bus at the same time, resulting in undefined behavior.

Use request_muxed_region() to ensure that IO access on the requested address space is supported, and to ensure that access by multiple drivers is synchronized.

In 2D transfers (for the AXI DMAC), the number of frames (numf) represents Y_LENGTH, and the length of a frame is X_LENGTH. 2D transfers are useful for video transfers where screen resolutions ( X * Y ) are typically aligned for X, but not for Y.

There is no requirement for Y_LENGTH to be aligned to the bus-width (or anything), and this is also true for AXI DMAC.

Checking the Y_LENGTH for alignment causes false errors when initiating DMA transfers. This change fixes this by checking only that the Y_LENGTH is non-zero.

Packet send checks that msg_name is at least sizeof sockaddr_ll. Packet recv must return at least this length, so that its output can be passed unmodified to packet send.

This ceased to be true since adding support for lladdr longer than sll_addr. Since, the return value uses true address length.

Always return at least sizeof sockaddr_ll, even if address length is shorter. Zero the padding bytes.

Change v1->v2: do not overwrite zeroed padding again. use copy_len.

The kernel parameter igfx_off is used by users to disable DMA remapping for the Intel integrated graphic device. It was designed for bare metal cases where a dedicated IOMMU is used for graphic. This doesn't apply to virtual IOMMU case where an include-all IOMMU is used. This makes the kernel parameter work with virtual IOMMU as well.

Commit f33e7bb3eb92 ("dmaengine: tegra210-adma: restore channel status") added support to save and restore the DMA channel registers when runtime suspending the ADMA. This change is causing the kernel to crash when probing the ADMA, if the device is probed deferred when looking up the channel interrupts. The crash occurs because not all of the channel base addresses have been setup at this point and in the clean-up path of the probe, pm_runtime_suspend() is called invoking its callback which expects all the channel base addresses to be initialised.

Although this could be fixed by simply checking for a NULL address, on further review of the driver it seems more appropriate that we only call pm_runtime_get_sync() after all the channel interrupts and base addresses have been configured. Therefore, fix this crash by moving the calls to pm_runtime_enable(), pm_runtime_get_sync() and tegra_adma_init() after the DMA channels have been initialised.

The locking in force_sig_info is not prepared to deal with a task that exits or execs (as sighand may change). The is not a locking problem in force_sig as force_sig is only built to handle synchronous exceptions.

Further the function force_sig_info changes the signal state if the signal is ignored, or blocked or if SIGNAL_UNKILLABLE will prevent the delivery of the signal. The signal SIGKILL can not be ignored and can not be blocked and SIGNAL_UNKILLABLE won't prevent it from being delivered.

So using force_sig rather than send_sig for SIGKILL is confusing and pointless.

Because it won't impact the sending of the signal and and because using force_sig is wrong, replace force_sig with send_sig.

Besides the alarm, the PCF8563 also has a timer triggered interrupt. In cases where the previous system left the timer and interrupts on, or somehow the bits got enabled, the interrupt would keep triggering as the kernel doesn't know about it.

Clear both the alarm and timer event flags, and disable the interrupts, before requesting the interrupt line.
