Hi Linus,
Please pull the following arm64 fixes for 4.3-rc2. They address some problems with filesystem writeback due to the recently merged hardware DBM patches, which caused us to treat some read-only pages as dirty.
There are also some other, less significant fixes that are described in the tag.
Cheers,
Will

arm64: errata: add module build workaround for erratum #843419 (2015-09-17 11:57:03 +0100)
---------------------------------------------------------------- arm64 fixes for 4.3-rc2
A mixture of fixes for regressions introduced during the merge window, some longer standing problems that we spotted and a couple of hardware errata. The main changes are:
- Fix fallout from the h/w DBM patches, causing filesystem writeback issues on both v8 and v8.1 CPUs - Workaround for Cortex-A53 erratum #843419 in the module loader - Fix for long-standing issue with compat big-endian signal handlers using the saved floating point state
---------------------------------------------------------------- Catalin Marinas (2): arm64: Fix the pte_hw_dirty() check when AF/DBM is enabled arm64: Fix pte_modify() to preserve the hardware dirty information
Jisheng Zhang (1): arm64: dma-mapping: check whether cma area is initialized or not
Leo Yan (1): arm64: enable generic idle loop
Will Deacon (5): arm64: pgtable: use a single bit for PTE_WRITE regardless of DBM arm64: head.S: initialise mdcr_el2 in el2_setup arm64: cpu hotplug: ensure we mask out CPU_TASKS_FROZEN in notifiers arm64: compat: fix vfp save/restore across signal handlers in big-endian arm64: errata: add module build workaround for erratum #843419
