The RSTOUT register on the Armada 370 SoC variant is a dedicated register (not shared across orthogonal subsystems) and so it's not needed to write it atomically.

Separate the RSTOUT register mapping for the different compatible strings supported by the driver. This allows to use devm_ioremap on SoC variants that share the RSTOUT register, and devm_ioremap_resource (which requests the MMIO region) on SoCs that have a dedicated RSTOUT register.

This watchdog driver will be working on IMX2+, Vybrid, LS1, LS2+ platforms, and will be in different endianness mode in those SoCs: SoCs CPU endian mode WDT endian mode ------------------------------------------------ IMX2+ LE LE Vybird LE LE LS1 LE BE LS2 LE LE Other possible SoCs: SoCs CPU endian mode WDT endian mode ------------------------------------------------ Soc1 BE BE Soc2 BE LE And also the watchdog's registers will be 32-bits for some versions, and though it is 16-bits in IMX2+, Vybird and LS+. Using the regmap APIs, could be more easy to support different endianness and also more easy to support 32-bits version...

On some AR934x based systems, where the frequency of the AHB bus is relatively high, the built-in watchdog causes a spurious restart when it gets enabled. The possible cause of these restarts is that the timeout value written into the TIMER register does not reaches the hardware in time. Add an explicit delay into the ath79_wdt_enable function to avoid the spurious restarts.

This function is supposed to return true if the new load imbalance is worse than the old one. It didn't. I can only hope brown paper bags are in style. Now things converge much better on both the 4 node and 8 node systems. I am not sure why this did not seem to impact specjbb performance on the 4 node system, which is the system I have full-time access to.

shrink_inactive_list() used to wait 0.1s to avoid congestion when all the pages that were isolated from the inactive list were dirty but not under active writeback. That makes no real sense, and apparently causes major interactivity issues under some loads since 3.11. The ostensible reason for it was to wait for kswapd to start writing pages, but that seems questionable as well, since the congestion wait code seems to trigger for kswapd itself as well. Also, the logic behind delaying anything when we haven't actually started writeback is not clear - it only delays actually starting that writeback. We'll still trigger the congestion waiting if (a) the process is kswapd, and we hit pages flagged for immediate reclaim (b) the process is not kswapd, and the zone backing dev writeback is actually congested. This probably needs to be revisited, but as it is this fixes a reported regression.

Patch to prevent warning of a buggy compiler when using clang and the ARM_UNWIND option. Clang defines (at least on the current trunk) GNUC, GNUC_MINOR, and GNUC_PATCHLEVEL to 4, 2, and 1 respectively. This version of GCC gets flagged as buggy, but it isn't actually an issue with clang so the patch will do what it did before unless clang is defined and then it will not report the GCC version as an issue.

Replaced non-standard C use of Variable Length Arrays In Structs (VLAIS) in xt_repldata.h with a C99 compliant flexible array member and then calculated offsets to the other struct members. These other members aren't referenced by name in this code, however this patch maintains the same memory layout and padding as was previously accomplished using VLAIS. Had the original structure been ordered differently, with the entries VLA at the end, then it could have been a flexible member, and this patch would have been a lot simpler. However since the data stored in this structure is ultimately exported to userspace, the order of this structure can't be changed. This patch makes no attempt to change the existing behavior, merely the way in which the current layout is accomplished using standard C99 constructs. As such the code can now be compiled with either gcc or clang. This version of the patch removes the trailing alignment that the VLAIS structure would allocate in order to simplify the patch.

commit 7d453eee ("x86/efi: Wire up CONFIG_EFI_MIXED") introduced a regression for the functionality to load kernels above 4G. The relevant (incorrect) reasoning behind this change can be seen in the commit message, "The xloadflags field in the bzImage header is also updated to reflect that the kernel supports both entry points by setting both of XLF_EFI_HANDOVER_32 and XLF_EFI_HANDOVER_64 when CONFIG_EFI_MIXED=y. XLF_CAN_BE_LOADED_ABOVE_4G is disabled so that the kernel text is guaranteed to be addressable with 32-bits." This is obviously bogus since 32-bit EFI loaders will never place the kernel above the 4G mark. So this restriction is entirely unnecessary. But things are worse than that - since we want to encourage people to always compile with CONFIG_EFI_MIXED=y so that their kernels work out of the box for both 32-bit and 64-bit firmware, commit 7d453eee effectively disables XLF_CAN_BE_LOADED_ABOVE_4G completely. Remove the overzealous and superfluous restriction and restore the XLF_CAN_BE_LOADED_ABOVE_4G functionality. Cc: "H.

Commit b6963327 ("ufs: drop lock/unlock super") removed lock/unlock super and added struct mutex 's_lock' in sb_info. Those 2 mutexes are generally locked/unlocked at the same time except in allocation (balloc, ialloc). This patch merges the 2 mutexes and propagates first commit solution. It also adds mutex destruction before kfree during ufs_fill_super failure and ufs_put_super.

As of commit 8dc7c5ec ("cris: Use generic idle loop"), cris no longer provides cpu_idle(). - On cris-v10, etrax_gpio_wake_up_check() is called from default_idle() instead of cpu_idle(), - On cris-v32, etrax_gpio_wake_up_check() is not called from default_idle(), so remove this (copy-and-paste?) part.
