Give upper layers a chance to reencode the message after the connection is negotiated and ->peer_features is set. OSD client will use this to support both luminous and pre-luminous OSDs (in a single cluster): the former need MOSDOp v8; the latter will continue to be sent MOSDOp v4.

Current ceph uses FSID as primary index key of fscache data. This allows ceph to retain cached data across remount. But this causes problem (kernel opps, fscache does not support sharing data) when a filesystem get mounted several times (with fscache enabled, with different mount options). The fix is adding a new mount option, which specifies uniquifier for fscache.

Previously we were returning values for quota, layout xattrs without any kind of update -- the user just got whatever happened to be in our cache. Clearly this extra round trip has a cost, but reads of these xattrs are fairly rare, happening on admin intervention rather than in normal operation.

uapi/linux/a.out.h uses a number of predefined macros that are deprecated because they're in the application namespace (e.g. '#ifdef linux' instead of '#ifdef __linux__'). This patch either corrects or just removes them if they are not applicable to Linux. The primary reason this is worth bothering to fix, considering how obsolete a.out binary support is, is that the GCC build process considers this such a severe error that it will copy the header into a private directory and change the macro names, which causes future updates to the header to be masked. This header probably doesn't get updated very often anymore, but it is the _only_ uapi header that gets this treatment, so IMHO it is worth patching just to drive that number all the way to zero.

Pull powerpc fixes from Michael Ellerman: "Hopefully the last two powerpc fixes for 4.12. The CXL one is larger than I'd usually send at rc7, but it fixes new code this cycle, so better to have it working for the release. It was actually sent a few weeks back but got blocked in testing behind another fix that was causing issues. We are still tracking one crash in v4.12-rc7, but only one person has reproduced it and the commit identified by bisect doesn't touch any of the relevant code, so I think it's 50/50 whether that commit is actually the problem or it's some code layout / toolchain issue.

Kernel text KASLR is separated into physical address and virtual address randomization. And for virtual address randomization, we only randomiza to get an offset between 16M and KERNEL_IMAGE_SIZE. So the initial value of 'virt_addr' should be LOAD_PHYSICAL_ADDR, but not the original kernel loading address 'output'. The bug will cause kernel boot failure if kernel is loaded at a different position than the address, 16M, which is decided at compiled time. Kexec/kdump is such practical case. To fix it, just assign LOAD_PHYSICAL_ADDR to virt_addr as initial value.
