2019-05-28mmc: meson-gx: fix irq ackJerome Brunet
While cleaning the ISR of the meson-gx and acking only raised irqs, the ack of the irq was moved at the very last stage of the function. This was stable during the initial tests but it triggered issues with hs200, under specific loads (like booting android). Acking the irqs after calling the mmc_request_done() causes the problem. Moving the ack back to the original place solves the issue. Since the irq is edge triggered, it does not hurt to ack irq even earlier, so let's do it early in the ISR.

If an SCC error occurs during a read/write command execution, a false positive CRC error message is output. mmcblk0: response CRC error sending r/w cmd command, card status 0x900 check_scc_error() checks SCC_RVSREQ.RVSERR bit. RVSERR detects a correction error in the next (up or down) delay tap position. However, since the command is successful, only retuning needs to be executed. This has been confirmed by HW engineers. Thus, on SCC error, set retuning flag instead of setting an error code.

2019-05-28drm/i915: Keep user GGTT alive for a minimum of 250msChris Wilson
Do not allow runtime pm autosuspend to remove userspace GGTT mmaps too quickly. For example, igt sets the autosuspend delay to 0, and so we immediately attempt to perform runtime suspend upon releasing the wakeref. Unfortunately, that involves tearing down GGTT mmaps as they require an active device. Override the autosuspend for GGTT mmaps, by keeping the wakeref around for 250ms after populating the PTE for a fresh mmap. v2: Prefer refcount_t for its under/overflow error detection v3: Flush the user runtime autosuspend prior to system system.

2019-05-28ALSA: line6: Assure canceling delayed work at disconnectionTakashi Iwai
The current code performs the cancel of a delayed work at the late stage of disconnection procedure, which may lead to the access to the already cleared state. This patch assures to call cancel_delayed_work_sync() at the beginning of the disconnection procedure for avoiding that race. The delayed work object is now assigned in the common line6 object instead of its derivative, so that we can call cancel_delayed_work_sync(). Along with the change, the startup function is called via the new callback instead. This will make it easier to port other LINE6 drivers to use the delayed work for startup in later patches.

2019-05-28configfs: Fix use-after-free when accessing sd->s_dentrySahitya Tummala
In the vfs_statx() context, during path lookup, the dentry gets added to sd->s_dentry via configfs_attach_attr(). In the end, vfs_statx() kills the dentry by calling path_put(), which invokes configfs_d_iput(). Ideally, this dentry must be removed from sd->s_dentry but it doesn't if the sd->s_count >= 3. As a result, sd->s_dentry is holding reference to a stale dentry pointer whose memory is already freed up. This results in use-after-free issue, when this stale sd->s_dentry is accessed later in configfs_readdir() path. This issue can be easily reproduced, by running the LTP test case - sh fs_racer_file_list.sh /config (https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/fs/racer/fs_racer_file_list.sh) Fixes: 76ae281f6307 ('configfs: fix race between dentry put and lookup') Signed-off-by: Sahitya Tummala <stummala@codeaurora.org> Signed-off-by: Christoph Hellwig <hch@lst.de>

2019-05-27drm/i915: Make sure we have enough memory bandwidth on ICLVille Syrjälä
ICL has so many planes that it can easily exceed the maximum effective memory bandwidth of the system. We must therefore check that we don't exceed that limit. The algorithm is very magic number heavy and lacks sufficient explanation for now. We also have no sane way to query the memory clock and timings, so we must rely on a combination of raw readout from the memory controller and hardcoded assumptions. The memory controller values obviously change as the system jumps between the different SAGV points, so we try to stabilize it first by disabling SAGV for the duration of the readout. The utilized bandwidth is tracked via a device wide atomic private object. That is actually not robust because we can't afford to enforce strict global ordering between the pipes. Thus I think I'll need to change this to simply chop up the available bandwidth between all the active pipes. Each pipe can then do whatever it wants as long as it doesn't exceed its budget. That scheme will also require that we assume that any number of planes could be active at any time. TODO: make it robust and deal with all the open questions v2: Sleep longer after disabling SAGV v3: Poll for the dclk to get raised (seen it take 250ms!) If the system has 2133MT/s memory then we pointlessly wait one full second :( v4: Use the new pcode interface to get the qgv points rather that using hardcoded numbers v5: Move the pcode stuff into intel_bw.c (Matt) s/intel_sagv_info/intel_qgv_info/ Do the NV12/P010 as per spec for now (Matt) s/IS_ICELAKE/IS_GEN11/ v6: Ignore bandwidth limits if the pcode query fails Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Acked-by: Clint Taylor <Clinton.A.Taylor@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190524153614.32410-1-ville.syrjala@linux.intel.com

Thats a known quirk in windows tcp stack it can produce 0xffff checksum. Thats incorrect but it is. Atlantic HW with LRO enabled handles that incorrectly and changes csum to 0xfffe - but indicates that csum is invalid. This causes driver to pass packet to linux networking stack with CSUM_NONE, stack eventually drops the packet. There is a quirk in atlantic HW to enable correct processing of 0xffff incorrect csum.
