Pull documentation fixes from Jonathan Corbet: "The Sphinx 2.0 release contained a few incompatible API changes that broke our extensions and, thus, the documentation build in general. Who knew that those deprecation warnings it was outputting actually meant we should change something? This set of fixes makes the build work again with Sphinx 2.0 and eliminates the warnings for 1.8. As part of that, we also need a few fixes to the docs for places where the new Sphinx is more strict. It is a bit late in the cycle for this kind of change, but it does fix problems that people are experiencing now. There has been some talk of raising the minimum version of Sphinx we support. I don't want to do that abruptly, though, so these changes add some glue to continue to support versions back to 1.3. We will be adding some infrastructure soon to nudge users of old versions forward, with the idea of maybe increasing our minimum version (and removing this glue) sometime in the future" * tag 'docs-5.2-fixes2' of git://git.lwn.net/linux: drm/i915: Maintain consistent documentation subsection ordering scripts/sphinx-pre-install: make it handle Sphinx versions docs: Fix conf.py for Sphinx 2.0 docs: fix multiple doc build warnings in enumeration.rst lib/list_sort: fix kerneldoc build error docs: fix numaperf.rst and add it to the doc tree doc: Cope with the deprecation of AutoReporter doc: Cope with Sphinx logging deprecations

devm functions are fine for managing resources that are directly related to the device at hand and that have no other dependencies. However, a process holding a file handle to a device created by a driver for a device may result in the file handle left behind after the device is long gone. This will result in accessing released (and potentially reallocated) memory. Instead, manage the memory resources in the driver. Releasing the resources can be later on bound to e.g. by releasing a reference.

2019-05-29net: sh_eth: fix mdio access in sh_eth_close() for R-Car Gen2 and RZ/A1 SoCsYoshihiro Shimoda
The sh_eth_close() resets the MAC and then calls phy_stop() so that mdio read access result is incorrect without any error according to kernel trace like below: ifconfig-216 [003] .n.. 109.133124: mdio_access: ee700000.ethernet-ffffffff read phy:0x01 reg:0x00 val:0xffff According to the hardware manual, the RMII mode should be set to 1 before operation the Ethernet MAC. However, the previous code was not set to 1 after the driver issued the soft_reset in sh_eth_dev_exit() so that the mdio read access result seemed incorrect. To fix the issue, this patch adds a condition and set the RMII mode register in sh_eth_dev_exit() for R-Car Gen2 and RZ/A1 SoCs. Note that when I have tried to move the sh_eth_dev_exit() calling after phy_stop() on sh_eth_close(), but it gets worse (kernel panic happened and it seems that a register is accessed while the clock is off).

2019-05-29MIPS: pistachio: Build uImage.gz by defaultPaul Burton
The pistachio platform uses the U-Boot bootloader & generally boots a kernel in the uImage format. As such it's useful to build one when building the kernel, but to do so currently requires the user to manually specify a uImage target on the make command line. Make uImage.gz the pistachio platform's default build target, so that the default is to build a kernel image that we can actually boot on a board such as the MIPS Creator Ci40. Marked for stable backport as far as v4.1 where pistachio support was introduced. This is primarily useful for CI systems such as kernelci.org which will benefit from us building a suitable image which can then be booted as part of automated testing, extending our test coverage to the affected stable branches.

2019-05-29MIPS: Bounds check virt_addr_validPaul Burton
The virt_addr_valid() function is meant to return true iff virt_to_page() will return a valid struct page reference. This is true iff the address provided is found within the unmapped address range between PAGE_OFFSET & MAP_BASE, but we don't currently check for that condition. Instead we simply mask the address to obtain what will be a physical address if the virtual address is indeed in the desired range, shift it to form a PFN & then call pfn_valid(). This can incorrectly return true if called with a virtual address which, after masking, happens to form a physical address corresponding to a valid PFN. For example we may vmalloc an address in the kernel mapped region starting a MAP_BASE & obtain the virtual address: addr = 0xc000000000002000 When masked by virt_to_phys(), which uses __pa() & in turn CPHYSADDR(), we obtain the following (bogus) physical address: addr = 0x2000 In a common system with PHYS_OFFSET=0 this will correspond to a valid struct page which should really be accessed by virtual address PAGE_OFFSET+0x2000, causing virt_addr_valid() to incorrectly return 1 indicating that the original address corresponds to a struct page. This is equivalent to the ARM64 change made in commit ca219452c6b8 ("arm64: Correctly bounds check virt_addr_valid"). This fixes fallout when hardened usercopy is enabled caused by the related commit 517e1fbeb65f ("mm/usercopy: Drop extra is_vmalloc_or_module() check") which removed a check for the vmalloc range that was present from the introduction of the hardened usercopy feature.

2019-05-29IB/rdmavt: Fix alloc_qpn() WARN_ON()Mike Marciniszyn
The qpn allocation logic has a WARN_ON() that intends to detect the use of an index that will introduce bits in the lower order bits of the QOS bits in the QPN. Unfortunately, it has the following bugs: - it misfires when wrapping QPN allocation for non-QOS - it doesn't correctly detect low order QOS bits (despite the comment) The WARN_ON() should not be applied to non-QOS (qos_shift == 1). Additionally, it SHOULD test the qpn bits per the table below: 2 data VLs: [qp7, qp6, qp5, qp4, qp3, qp2, qp1] ^ [ 0, 0, 0, 0, 0, 0, sc0], qp bit 1 always 0* 3-4 data VLs: [qp7, qp6, qp5, qp4, qp3, qp2, qp1] ^ [ 0, 0, 0, 0, 0, sc1, sc0], qp bits [21] always 0 5-8 data VLs: [qp7, qp6, qp5, qp4, qp3, qp2, qp1] ^ [ 0, 0, 0, 0, sc2, sc1, sc0] qp bits [321] always 0 Fix by qualifying the warning for qos_shift > 1 and producing the correct mask to insure the above bits are zero without generating a superfluous warning.

2019-05-29ASoC: sun4i-codec: fix first delay on SpeakerGeorgii Staroselskii
Allwinner DAC seems to have a delay in the Speaker audio routing. When playing a sound for the first time, the sound gets chopped. On a second play the sound is played correctly. After some time (~5s) the issue gets back. This commit seems to be fixing the same issue as bf14da7 but for another codepath. This is the DTS that was used to debug the problem. &codec { allwinner,pa-gpios = <&r_pio 0 11 GPIO_ACTIVE_HIGH>; /* PL11 */ allwinner,audio-routing = "Speaker", "LINEOUT"; status = "okay"; } Signed-off-by: Georgii Staroselskii <georgii.staroselskii@emlid.com> Reviewed-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-05-29media: sun6i: Support A83T variantChen-Yu Tsai
The A83T SoC has a camera sensor interface (known as CSI in Allwinner lingo), which is similar to the one found on the A64 and H3. The only difference seems to be that support of MIPI CSI through a connected MIPI CSI-2 bridge. Add support for this variant.
