Patch 1 is just a style fix, trivial. Patch 8 adds helper_reset_fpstatus() calls to instructions that have an issue where the exception flags are being kept from the previous instruction, causing incorrect bits to be set, specially the non-sticky FI bit. Other patches fixes other specific situations. v1->v2: - Squash patches 8 through 19 and write a better commit message to it. - Dropped Daniel's R-b in the squashed patches, as the squash merged both reviewed and non-reviewed patches. Now require a new, single R-b.
