Pull nfsd changes from J Bruce Fields: "Highlights include: - Some more DRC cleanup and performance work from Jeff Layton - A gss-proxy upcall from Simo Sorce: currently krb5 mounts to the server using credentials from Active Directory often fail due to limitations of the svcgssd upcall interface. This replacement lifts those limitations. The existing upcall is still supported for backwards compatibility. - More NFSv4.1 support: at this point, if a user with a current client who upgrades from 4.0 to 4.1 should see no regressions. In theory we do everything a 4.1 server is required to do. Patches for a couple minor exceptions are ready for 3.11, and with those and some more testing I'd like to turn 4.1 on by default in 3.11." Fix up semantic conflict as per Stephen Rothwell and linux-next: Commit 030d794b ("SUNRPC: Use gssproxy upcall for server RPCGSS authentication") adds two new users of "PDE(inode)->data", but we're supposed to use "PDE_DATA(inode)" instead since commit d9dda78b ("procfs: new helper - PDE_DATA(inode)").

We can step on WARN_ON_ONCE() in sem_getref() if a semaphore is removed just as we are about to call sem_getref() from semctl_main(); results are not pretty. We should fail with -EIDRM, same as if IPC_RM happened while we'd been doing allocation there. This also expands sem_getref() at its only callsite (and fixed there), while sem_getref_and_unlock() is simply killed off - it has no callers at all.

Pull i2c changes from Wolfram Sang: - an arbitration driver. While the driver is quite simple, it caused discussion if we need additional arbitration on top of the one specified in the I2C standard. Conclusion is that I accept a few generic mechanisms, but not very specific ones. - the core lost the detach_adapter() call. It has no users anymore and was in the way for other cleanups. attach_adapter() is sadly still there since there are users waiting to be converted. - the core gained a bus recovery infrastructure. I2C defines a way to recover if the data line is stalled. This mechanism is now in the core and drivers can now pass some data to make use of it. - bigger driver cleanups for designware, s3c2410 - removing superfluous refcounting from drivers - removing Ben Dooks as second maintainer due to inactivity.

Consistently check errors using the usual method used in the kernel for much of its history. For instance: int gpmc_cs_set_timings(int cs, const struct gpmc_timings *t) { int div; div = gpmc_calc_divider(t->sync_clk); if (div < 0) return div; static int gpmc_set_async_mode(int cs, struct gpmc_timings *t) { ... return gpmc_cs_set_timings(cs, t); ..... ret = gpmc_set_async_mode(gpmc_onenand_data->cs, &t); if (IS_ERR_VALUE(ret)) return ret; So, gpmc_cs_set_timings() thinks any negative return value is an error, but where we check that in higher levels, only a limited range are errors... There is only _one_ use of IS_ERR_VALUE() in arch/arm which is really appropriate, and that is in arch/arm/include/asm/syscall.h: static inline long syscall_get_error(struct task_struct *task, struct pt_regs *regs) { unsigned long error = regs->ARM_r0; return IS_ERR_VALUE(error) ? error : 0; } because this function really does have to differentiate between error return values and addresses which look like negative numbers (eg, from mmap()). So, here's a patch to remove them from OMAP, except for the above. Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

omap_hwmod_lookup() only returns NULL on error, never an error pointer. Checking the returned pointer using IS_ERR_OR_NULL() is needless overhead. Use a simple !ptr check instead. OMAP devices (oh->od) always have a valid platform device attached (see omap_device_alloc()) so there's no point validating the platform device pointer (we will have already oopsed long before if this is not the case here.) Lastly, oh->od is only ever NULL or a valid omap device pointer - 'oh' comes from the statically declared hwmod tables, and the pointer is only filled in by omap_device_alloc() at a point where the omap device pointer must be valid.

During early init, we would incorrectly set the NX bit even if the NX feature was not supported. Instead, only set this bit if NX is actually available and enabled. We already do very early detection of the NX bit to enable it in EFER, this simply extends this detection to the early page table mask.

The git commite7a5cd06 ("x86-64, gdt: Store/load GDT for ACPI S3 or hibernate/resume path is not needed.") assumes that for the hibernate path the booting kernel and the resuming kernel MUST be the same. That is certainly the case for a 32-bit kernel (see check_image_kernel and CONFIG_ARCH_HIBERNATION_HEADER config option). However for 64-bit kernels it is OK to have a different kernel version (and size of the image) of the booting and resuming kernels. Hence the above mentioned git commit introduces an regression. This patch fixes it by introducing a 'struct desc_ptr gdt_desc' back in the 'struct saved_context'. However instead of having in the 'save_processor_state' and 'restore_processor_state' the store/load_gdt calls, we are only saving the GDT in the save_processor_state. For the restore path the lgdt operation is done in hibernate_asm_[32|64].S in the 'restore_registers' path. The apt reader of this description will recognize that only 64-bit kernels need this treatment, not 32-bit. This patch adds the logic in the 32-bit path to be more similar to 64-bit so that in the future the unification process can take advantage of this.

Pull powerpc update from Benjamin Herrenschmidt: "The main highlights this time around are: - A pile of addition POWER8 bits and nits, such as updated performance counter support (Michael Ellerman), new branch history buffer support (Anshuman Khandual), base support for the new PCI host bridge when not using the hypervisor (Gavin Shan) and other random related bits and fixes from various contributors. - Some rework of our page table format by Aneesh Kumar which fixes a thing or two and paves the way for THP support. THP itself will not make it this time around however. - More Freescale updates, including Altivec support on the new e6500 cores, new PCI controller support, and a pile of new boards support and updates. - The usual batch of trivial cleanups & fixes" * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (156 commits) powerpc: Fix build error for book3e powerpc: Context switch the new EBB SPRs powerpc: Turn on the EBB H/FSCR bits powerpc: Replace CPU_FTR_BCTAR with CPU_FTR_ARCH_207S powerpc: Setup BHRB instructions facility in HFSCR for POWER8 powerpc: Fix interrupt range check on debug exception powerpc: Update tlbie/tlbiel as per ISA doc powerpc: Print page size info during boot powerpc: print both base and actual page size on hash failure powerpc: Fix hpte_decode to use the correct decoding for page sizes powerpc: Decode the pte-lp-encoding bits correctly. powerpc: Use encode avpn where we need only avpn values powerpc: Reduce PTE table memory wastage powerpc: Move the pte free routines from common header powerpc: Reduce the PTE_INDEX_SIZE powerpc: Switch 16GB and 16MB explicit hugepages to a different page table format powerpc: New hugepage directory format powerpc: Don't truncate pgd_index wrongly powerpc: Don't hard code the size of pte page powerpc: Save DAR and DSISR in pt_regs on MCE ...

Pull ARM SoC multiplatform updates from Olof Johansson: "More multiplatform enablement for ARM platforms. The ones converted in this branch are: - bcm2835 - cns3xxx - sirf - nomadik - msx - spear - tegra - ux500 We're getting close to having most of them converted! One of the larger platforms remaining is Samsung Exynos, and there are a bunch of supporting patches in this merge window for it. There was a patch in this branch to a early version of multiplatform conversion, but it ended up being reverted due to need of more bake time.
