The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate.

Pull vfs fix from Al Viro: "Off-by-one in d_walk()/__dentry_kill() race fix. It's very hard to hit; possible in the same conditions as the original bug, except that you need the skipped branch to contain all the remaining evictables, so that the d_walk()-calling loop in d_invalidate() decides there's nothing more to do and doesn't go for another pass - otherwise that next pass will sweep the sucker. So it's not too urgent, but seeing that the fix is obvious and the original commit has spread into all -stable branches..." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: d_walk() might skip too much

There is just one configfs subsystem in the target code, so we might as well add two helpers to reference / unreference it from the core code instead of passing pointers to it around. This fixes a regression introduced for v4.1-rc1 with commit 9ac8928e, where configfs_depend_item() callers using se_tpg_tfo->tf_subsys would fail, because the assignment from the original target_core_subsystem[] is no longer happening at target_register_template() time.

Pull PCI / ACPI fix from Rafael Wysocki: "This fixes a bug uncovered by a recent driver core change that modified the implementation of the ACPI_COMPANION_SET() macro to strictly rely on its second argument to be either NULL or a valid pointer to struct acpi_device. As it turns out, pcibios_root_bridge_prepare() on x86 and ia64 works with the assumption that the only code path calling pci_create_root_bus() is pci_acpi_scan_root() and therefore the sysdata argument passed to it will always match the expectations of pcibios_root_bridge_prepare(). That need not be the case, however, and in particular it is not the case for the Xen pcifront driver that passes a pointer to its own private data strcture as sysdata to pci_scan_bus_parented() which then passes it to pci_create_root_bus() and it ends up being used incorrectly by pcibios_root_bridge_prepare()" * tag 'acpi-pci-4.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PCI / ACPI: Do not set ACPI companions for host bridges with parents

Correct a regression introduced with 8453eebd [MIPS: Fix strnlen_user() return value in case of overlong strings.] causing assembler warnings and broken code generated in __strnlen_kernel_nocheck_asm: arch/mips/lib/strnlen_user.S: Assembler messages: arch/mips/lib/strnlen_user.S:64: Warning: Macro instruction expanded into multiple instructions in a branch delay slot with the CPU_DADDI_WORKAROUNDS option set, resulting in the function looping indefinitely upon mounting NFS root. Use conditional assembly to avoid a microMIPS code size regression. Using $at unconditionally would cause such a regression as there are no 16-bit instruction encodings available for ALU operations using this register. Using $v1 unconditionally would produce short microMIPS encodings, but would prevent this register from being used across calls to this function.

Joe Thornber authored
dm_merge_bvec() was originally added in f6fccb ("dm: introduce merge_bvec_fn"). In that commit a value in sectors is converted to bytes using << 9, and then assigned to an int. This code made assumptions about the value of BIO_MAX_SECTORS. A later commit 148e51 ("dm: improve documentation and code clarity in dm_merge_bvec") was meant to have no functional change but it removed the use of BIO_MAX_SECTORS in favor of using queue_max_sectors(). At this point the cast from sector_t to int resulted in a zero value. The fallout being dm_merge_bvec() would only allow a single page to be added to a bio. This interim fix is minimal for the benefit of stable@ because the more comprehensive cleanup of passing a sector_t to all DM targets' merge function will impact quite a few DM targets.

When stacking request-based dm device on non blk-mq device and device-mapper target could not map the request (error target is used, multipath target with all paths down, etc), the WARN_ON_ONCE() in free_rq_clone() will trigger when it shouldn't. The warning was added by commit aa6df8dd ("dm: fix free_rq_clone() NULL pointer when requeueing unmapped request"). But free_rq_clone() with clone->q == NULL is valid usage for the case where dm_kill_unmapped_request() initiates request cleanup. Fix this false warning by just removing the WARN_ON -- it only generated false positives and was never useful in catching the intended case (completing clone request not being mapped e.g. clone->q being NULL).

The commit [49fb1897: ALSA: hda - Set stream_pm ops automatically by generic parser] resulted in regressions on some Realtek and VIA codecs because these drivers set patch_ops after calling the generic parser, thus stream_pm got cleared to NULL again. I haven't noticed since I tested with IDT codec. Restore (partial revert) the stream_pm ops for them to fix the regression.
