2018-12-17mmc: slot-gpio: Allocate GPIO labels dynamicallyLinus Walleij1-6/+10
The use of string pointers in the MMC slot GPIO context is pretty dubious, allocating some 2*len extra bytes for each label of the ro and wp pins. Tidy this up using kasprintf() with dynamic allocation of labels for these strings. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2018-12-17mmc: sdhci-msm: Re-initialize DLL if MCLK is gated dynamicallyVeerabhadrarao Badiganti1-11/+67
On few SDHCI-MSM controllers, the host controller's clock tuning circuit may go out of sync if controller clocks are gated which eventually will result in data CRC, command CRC/timeout errors. To overcome this h/w limitation, the DLL needs to be re-initialized and restored with its old settings once clocks are ungated.

2018-12-17mmc: sdhci: Handle auto-command errorsAdrian Hunter2-1/+41
If the host controller supports auto-commands then enable the auto-command error interrupt and handle it. In the case of auto-CMD23, the error is treated the same as manual CMD23 error. In the case of auto-CMD12, commands-during-transfer are not permitted, so the error handling is treated the same as a data error.

2018-12-17mmc: sdhci: Fix data command CRC error handlingAdrian Hunter1-25/+15
Existing data command CRC error handling is non-standard and does not work with some Intel host controllers. Specifically, the assumption that the host controller will continue operating normally after the error interrupt, is not valid. Change the driver to handle the error in the same manner as a data CRC error, taking care to ensure that the data line reset is done for single or multi-block transfers, and it is done before unmapping DMA.

2018-12-15scripts/spdxcheck.py: always open files in binary modeThierry Reding1-2/+4
The spdxcheck script currently falls over when confronted with a binary file (such as Documentation/logo.gif). To avoid that, always open files in binary mode and decode line-by-line, ignoring encoding errors. One tricky case is when piping data into the script and reading it from standard input. By default, standard input will be opened in text mode, so we need to reopen it in binary mode. The breakage only happens with python3 and results in a UnicodeDecodeError (according to Uwe).

2018-12-15fs/iomap.c: get/put the page in iomap_page_create/release()Piotr Jaroszynski1-0/+7
migrate_page_move_mapping() expects pages with private data set to have a page_count elevated by 1. This is what used to happen for xfs through the buffer_heads code before the switch to iomap in commit 82cb14175e7d ("xfs: add support for sub-pagesize writeback without buffer_heads"). Not having the count elevated causes move_pages() to fail on memory mapped files coming from xfs. Make iomap compatible with the migrate_page_move_mapping() assumption by elevating the page count as part of iomap_page_create() and lowering it in iomap_page_release(). It causes the move_pages() syscall to misbehave on memory mapped files from xfs. It does not not move any pages, which I suppose is "just" a perf issue, but it also ends up returning a positive number which is out of spec for the syscall. Talking to Michal Hocko, it sounds like returning positive numbers might be a necessary update to move_pages() anyway though (https://lkml.kernel.org/r/20181116114955.GJ14706@dhcp22.suse.cz). I only hit this in tests that verify that move_pages() actually moved the pages. The test also got confused by the positive return from move_pages() (it got treated as a success as positive numbers were not expected and not handled) making it a bit harder to track down what's going on.

2018-12-15alpha: fix hang caused by the bootmem removalMike Rapoport2-3/+4
The conversion of alpha to memblock as the early memory manager caused boot to hang as described at [1]. The issue is caused because for CONFIG_DISCTONTIGMEM=y case, memblock_add() is called using memory start PFN that had been rounded down to the nearest 8Mb and it caused memblock to see more memory that is actually present in the system. Besides, memblock allocates memory from high addresses while bootmem was using low memory, which broke the assumption that early allocations are always accessible by the hardware. This patch ensures that memblock_add() is using the correct PFN for the memory start and forces memblock to use bottom-up allocations.

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: "One notable fix for our change to split pt_regs between user/kernel, we forgot to update BPF to use the user-visible type which was an ABI break for BPF programs. A slightly ugly but minimal fix to do_syscall_trace_enter() so that we use tracehook_report_syscall_entry() properly. We'll rework the code in next to avoid the empty if body. Seven commits fixing bugs in the new papr_scm (Storage Class Memory) driver. The driver was finally able to be tested on the other hypervisor which exposed several bugs. The fixes are all fairly minimal at least. Fix a crash in our MSI code if an MSI-capable device is plugged into a non-MSI capable PHB, only seen on older hardware (MPC8378). Fix our legacy serial code to look for "stdout-path" since the device trees were updated to use that instead of "linux,stdout-path". A change to the COFF zImage code to fix booting old powermacs.

Specifying a starting ID greater than the maximum ID isn't something attempted very often, but it should fail. It was succeeding due to xas_find_marked() returning the wrong error state, so add tests for both xa_alloc() and xas_find_marked().

2018-12-13drm/vmwgfx: Protect from excessive execbuf kernel memory allocations v3Thomas Hellstrom6-2/+103
With the new validation code, a malicious user-space app could potentially submit command streams with enough buffer-object and resource references in them to have the resulting allocated validion nodes and relocations make the kernel run out of GFP_KERNEL memory. Protect from this by having the validation code reserve TTM graphics memory when allocating.
