Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.12-20180410' into staging
ppc patch queue 2018-04-10 Here's a rather late pull request with a handful of fixes for 2.12. These have been blocked for some time, because I wasn't able to complete my usual test set due to the SCSI problem fixed in 37c5174 "scsi-disk: Don't enlarge min_io_size to max_io_size". Since we're in hard freeze, these are all bugfixes. Most are also regressions, although in one case it's only a "regression" because a longstanding bug has been exposed by a new machine type (sam460ex) in the testcases. There are also a couple of sam460ex fixes that aren't regressions since the board didn't exist before. On the flipside though, they're low risk because they only touch board specific code for a board that doesn't exist in any released version. # gpg: Signature made Tue 10 Apr 2018 08:13:52 BST # gpg: using RSA key 6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-2.12-20180410: roms/u-boot-sam460ex: Change to qemu git mirror and update sam460ex: Fix timer frequency and clock multipliers tests/boot-serial: Test the sam460ex board spapr: Initialize reserved areas list in FDT in H_CAS handler target/ppc: Fix backwards migration of msr_mask hw/misc/macio: Fix crash when listing device properties of macio device target/ppc: Initialize lazy_tlb_flush correctly Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
