Merge remote-tracking branch 'remotes/yongbok/tags/mips-20170803' into staging
MIPS patches 2017-08-03 Changes: KVM T&E segment support for TCG malta: leave space for the bootmap after the initrd Apply CP0.PageMask before writing into TLB entry Fix fallout from indirect branch optimisation # gpg: Signature made Thu 03 Aug 2017 15:32:59 BST # gpg: using RSA key 0x2238EB86D5F797C2 # gpg: Good signature from "Yongbok Kim <yongbok.kim@imgtec.com>" # gpg: WARNING: This key is not certified with sufficiently trusted signatures! # gpg: It is not certain that the signature belongs to the owner. # Primary key fingerprint: 8600 4CF5 3415 A5D9 4CFA 2B5C 2238 EB86 D5F7 97C2 * remotes/yongbok/tags/mips-20170803: target/mips: Fix RDHWR CC with icount target/mips: Drop redundant gen_io_start/stop() target/mips: Use BS_EXCP where interrupts are expected target-mips: apply CP0.PageMask before writing into TLB entry mips: Add KVM T&E segment support for TCG mips: Improve segment defs for KVM T&E guests mips/malta: leave space for the bootmap after the initrd target-mips: Don't stop on [d]mtc0 DESAVE/KScratch Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
