Merge remote-tracking branch 'remotes/bonzini/tags/for-upstream' into staging
* Log filtering from Alex and Peter * Chardev fix from Marc-André * config.status tweak from David * Header file tweaks from Markus, myself and Veronia (Outreachy candidate) * get_ticks_per_sec() removal from Rutuja (Outreachy candidate) * Coverity fix from myself * PKE implementation from myself, based on rth's XSAVE support # gpg: Signature made Thu 24 Mar 2016 20:15:11 GMT using RSA key ID 78C7AE83 # gpg: Good signature from "Paolo Bonzini <bonzini@gnu.org>" # gpg: aka "Paolo Bonzini <pbonzini@redhat.com>" * remotes/bonzini/tags/for-upstream: (28 commits) target-i386: implement PKE for TCG config.status: Pass extra parameters char: translate from QIOChannel error to errno exec: fix error handling in file_ram_alloc cputlb: modernise the debug support qemu-log: support simple pid substitution for logs target-arm: dfilter support for in_asm qemu-log: dfilter-ise exec, out_asm, op and opt_op qemu-log: new option -dfilter to limit output qemu-log: Improve the "exec" TB execution logging qemu-log: Avoid function call for disabled qemu_log_mask logging qemu-log: correct help text for -d cpu tcg: pass down TranslationBlock to tcg_code_gen util: move declarations out of qemu-common.h Replaced get_tick_per_sec() by NANOSECONDS_PER_SECOND hw: explicitly include qemu-common.h and cpu.h include/crypto: Include qapi-types.h or qemu/bswap.h instead of qemu-common.h isa: Move DMA_transfer_handler from qemu-common.h to hw/isa/isa.h Move ParallelIOArg from qemu-common.h to sysemu/char.h Move QEMU_ALIGN_*() from qemu-common.h to qemu/osdep.h ...
