2019-07-03usb: Handle USB3 remote wakeup for LPM enabled devices correctlyLee, Chiasheng
With Link Power Management (LPM) enabled USB3 links transition to low power U1/U2 link states from U0 state automatically. Current hub code detects USB3 remote wakeups by checking if the software state still shows suspended, but the link has transitioned from suspended U3 to enabled U0 state. As it takes some time before the hub thread reads the port link state after a USB3 wake notification, the link may have transitioned from U0 to U1/U2, and wake is not detected by hub code. Fix this by handling U1/U2 states in the same way as U0 in USB3 wakeup handling This patch should be added to stable kernels since 4.13 where LPM was kept enabled during suspend/resume Cc: <stable@vger.kernel.org> # v4.13+ Signed-off-by: Lee, Chiasheng <chiasheng.lee@intel.com> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2019-07-03drivers/usb/typec/tps6598x.c: fix 4CC cmd writeNikolaus Voss
Writing 4CC commands with tps6598x_write_4cc() already has a pointer arg, don't reference it when using as arg to tps6598x_block_write(). Correcting this enforces the constness of the pointer to propagate to tps6598x_block_write(), so add the const qualifier there to avoid the warning.

2019-07-03staging: erofs: fix LZ4 limited bounced page mis-reuseGao Xiang
Like all lz77-based algrithms, lz4 has a dynamically populated ("sliding window") dictionary and the maximum lookback distance is 65535. Therefore the number of bounced pages could be limited by erofs based on this property. However, just now we observed some lz4 sequences in the extreme case cannot be decompressed correctly after this feature is enabled, the root causes after analysis are clear as follows: 1) max bounced pages should be 17 rather than 16 pages; 2) considering the following case, the broken implementation could reuse unsafely in advance (in other words, reuse it less than a safe distance), 0 1 2 ... 16 17 18 ... 33 34 b p b b note that the bounce page that we are concerned was allocated at 0, and it reused at 18 since page 17 exists, but it mis-reused at 34 in advance again, which causes decompress failure. This patch resolves the issue by introducing a bitmap to mark whether the page in the same position of last round is a bounced page or not, and a micro stack data structure to store all available bounced pages.

2019-07-03intel_th: msu: Start read iterator from a non-empty windowAlexander Shishkin
In multi-window mode, the read iterator is supposed to start from the window with the oldest data, which is, chronologically, the next window after the one with the newest data. This, however, fails to take into account the potentially empty windows, so in short trace sessions it's possible to have a lot of zeroes read from the character device first. Fix this by skipping over the empty windows in initialization of the read iterator.

2019-07-03intel_th: msu: Fix single mode with disabled IOMMUAlexander Shishkin
Commit 4e0eaf239fb3 ("intel_th: msu: Fix single mode with IOMMU") switched the single mode code to use dma mapping pages obtained from the page allocator, but with IOMMU disabled, that may lead to using SWIOTLB bounce buffers and without additional sync'ing, produces empty trace buffers. Fix this by using a DMA32 GFP flag to the page allocation in single mode, as the device supports full 32-bit DMA addressing.

Commit ba39bd8306057 ("intel_th: msu: Switch over to scatterlist") introduced the following warnings on non-x86 architectures, as a result of reordering the multi mode buffer allocation sequence: > drivers/hwtracing/intel_th/msu.c: In function ‘msc_buffer_win_alloc’: > drivers/hwtracing/intel_th/msu.c:783:21: warning: unused variable ‘i’ > [-Wunused-variable] > int ret = -ENOMEM, i; > ^ > drivers/hwtracing/intel_th/msu.c: In function ‘msc_buffer_win_free’: > drivers/hwtracing/intel_th/msu.c:863:6: warning: unused variable ‘i’ > [-Wunused-variable] > int i; > ^ Fix this compiler warning by factoring out set_memory sequences and making them x86-only.
