+Subject: ARM: 7953/1: mm: ensure TLB invalidation is complete before enabling MMU
+
+From: Will Deacon <will.deacon@arm.com>
+
+commit bae0ca2bc550d1ec6a118fb8f2696f18c4da3d8e upstream.
+
+During __v{6,7}_setup, we invalidate the TLBs since we are about to
+enable the MMU on return to head.S. Unfortunately, without a subsequent
+dsb instruction, the invalidation is not guaranteed to have completed by
+the time we write to the sctlr, potentially exposing us to junk/stale
+translations cached in the TLB.
+
+This patch reworks the init functions so that the dsb used to ensure
+completion of cache/predictor maintenance is also used to ensure
+completion of the TLB invalidation.

+
+From: Marek Szyprowski <m.szyprowski@samsung.com>
+
+commit 10c8562f932d89c030083e15f9279971ed637136 upstream.
+
+GFP_ATOMIC is not a single gfp flag, but a macro which expands to the other
+flags and LACK of __GFP_WAIT flag. To check if caller wanted to perform an
+atomic allocation, the code must test __GFP_WAIT flag presence. This patch
+fixes the issue introduced in v3.6-rc5

+From: Pekon Gupta <pekon@ti.com>
+
+commit 6b187b21c92b6e2c7e8ef0b450181c37a3f31681 upstream.
+
+Fixes: commit bc6b1e7b86f5d8e4a6fc1c0189e64bba4077efe0
+ ARM: OMAP: gpmc: add DT bindings for GPMC timings and NAND
+
+OMAP SoC(s) depend on GPMC controller driver to parse GPMC DT child nodes and
+register them platform_device for NAND driver to probe later. However this does
+not happen if generic MTD_NAND framework is built as module (CONFIG_MTD_NAND=m).
+
+Therefore, when MTD/NAND and MTD/NAND/OMAP2 modules are loaded, they are unable
+to find any matching platform_device and remain un-binded. This causes on board
+NAND flash to remain un-detected.
