So this missed my normal Sunday release, because I was out most of the day yesterday. Plus there was a suspend regression that looked like it had a patch imminent, so I didn't bother making one late in the evening, hoping for one more fix..
So here it is, last-minute fix and all. The -rc4 patch is a bit bigger than the previous ones, but that seems to be mainly due to normal random timing - just the fluctuation of when submaintainer trees get pushed, and rc4 has fixes from Greg to various driver trees _and_ the networking fixes from Davem, so the slightly larger size isn't indicative of any sudden problems.
But while drivers and networking dominate the changes, there's a random smattering of other changes. Filesystems (btrfs, nfsd) and architecture updates (mainly arm, arm64 and mips) and some other misc changes.
Go forth and test, and let everybody know about any regressions you find,
