2016-02-29staging/hfi1: Enable TID caching featureMitko Haralanov
This commit "flips the switch" on the TID caching feature implemented in this patch series. As well as enabling the new feature by tying the new function with the PSM API, it also cleans up the old unneeded code, data structure members, and variables. Due to difference in operation and information, the tracing functions related to expected receives had to be changed. This patch include these changes. The tracing function changes could not be split into a separate commit without including both tracing variants at the same time. This would have caused other complications and ugliness.

2016-02-29staging/hfi1: Add TID entry program function bodyMitko Haralanov
The previous patch in the series added the free/invalidate function bodies. Now, it's time for the programming side. This large function takes the user's buffer, breaks it up into manageable chunks, allocates enough RcvArray groups and programs the chunks into the RcvArray entries in the hardware. With this function, the TID caching functionality is implemented. However, it is still unused. The switch will come in a later patch in the series, which will remove the old functionality and switch the driver over to TID caching.

Up to now, the functions which cleared the programmed TID entries and gave PSM the list of invalidated TID entries were just stubs. With this commit, the bodies of these functions are added.

Definitions and functions use to manage sets of TID/RcvArray groups. These will be used by the TID cacheline functionality coming with later patches. TID groups (or RcvArray groups) are groups of TID/RcvArray entries organized in sets of 8 and aligned on cacheline boundaries. The TID/RcvArray entries are managed in this way to make taking advantage of write-combining easier - each group is a entire cacheline. rcv_array_wc_fill() is provided to allow of generating writes to TIDs which are not currently being used in order to cause the flush of the write-combining buffer.

Highlights: - N900 fix for setting system revision - onenand init fix to avoid filesystem corruption - Clock fix for audio on Beaglebone-x15 - Fixes on shmobile to deal with CONFIG_DEBUG_RODATA (default y in 4.6) + misc smaller stuff" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: MAINTAINERS: Extend info, add wiki and ml for meson arch MAINTAINERS: alpine: add a new maintainer and update the entry ARM: at91/dt: fix typo in sama5d2 pinmux descriptions ARM: OMAP2+: Fix onenand initialization to avoid filesystem corruption Revert "regulator: tps65217: remove tps65217.dtsi file" ARM: shmobile: Remove shmobile_boot_arg ARM: shmobile: Move shmobile_smp_{mpidr, fn, arg}[] from .text to .bss ARM: shmobile: r8a7779: Remove remainings of removed SCU boot setup code ARM: shmobile: Move shmobile_scu_base from .text to .bss ARM: OMAP2+: Fix omap_device for module reload on PM runtime forbid ARM: OMAP2+: Improve omap_device error for driver writers ARM: DTS: am57xx-beagle-x15: Select SYS_CLK2 for audio clocks ARM: dts: am335x/am57xx: replace gpio-key,wakeup with wakeup-source property ARM: OMAP2+: Set system_rev from ATAGS for n900 ARM: dts: orion5x: fix the missing mtd flash on linkstation lswtgl ARM: dts: kirkwood: use unique machine name for ds112 ARM: dts: imx6: remove bogus interrupt-parent from CAAM node
