[ANNOUNCE] 4.14.52-rt34

[ANNOUNCE] 4.14.52-rt34

[Steven Rostedt]

Dear RT Folks,

I'm pleased to announce the 4.14.52-rt34 stable release.

This includes the merging of the stable releases, but also required
pulling in ("Revert mm/vmstat.c: fix vmstat_update() preemption BUG")
because v4.14.45 pulled in commit c7f26ccfb2c3 ("mm/vmstat.c: fix
vmstat_update() preemption BUG") which broke RT.

You can get this release via the git tree at:

  git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git

  branch: v4.14-rt
  Head SHA1: 71fbfbcfbcea9e6e5aa9dac068602f633dca5ad8


Or to build 4.14.52-rt34 directly, the following patches should be
applied:

  http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.14.tar.xz

  http://www.kernel.org/pub/linux/kernel/v4.x/patch-4.14.52.xz

  http://www.kernel.org/pub/linux/kernel/projects/rt/4.14/patch-4.14.52-rt34.patch.xz




Enjoy,

-- Steve

Is this new within the v4.14-rt tree (like a patch from the stable tree
caused it) or was it maybe always there?

I took his comment about "It now boots and works fine" meaning that it
didn't even boot before. Thus it is working better.

Yes, first build on arm64 box (just before you released -rt34) died
screaming.  Applying update, it just worked (modulo boot time splat).

I have attached a 60GB cheap ssd to a pi-3b by way of plugging in its 
usb-3 adapter cable to one of the 3b's usb-2 ports, and gave it 2 
working partitions, 49 GB of workspace, and 10+GB of swap in hopes that 
would stop the binutils explosions.  Seems to have worked, it built a 
previously pulled 4.14.y.rt.zip in about 8 hours.  But now I'd like to 
try the latest, but this doesn't seem to exist. Or should I just wait 
for the next announcement?

Thank you.

Link is correct including tags and everything.

this is correct http handling and this "moved permanently" is handled by
wget just fine.

It does, I just verified everything step by step.

That didn't seem to be the case for the armhf jessie version of wget this 
morning. I'd copy/paste what I got, but found the 4.4.4 .config its 
running right now, and used it as seed for a make oldconfig. That took 
about 1:30, but its timing a new make right now, and the shell history 
isn't deep enough to access it.

The old, running kernel has a problem with local keyboard/mouse events, 
it likes to throw them away. Not at all good when it told 1500 lbs of 
machinery to move, but threw away the key up event that would/should 
have stopped it.

So I'm trying to build a kernel that doesn't do that. And frankly no clue 
what I should poke at, or the size stick I need to actually accomplish 
this.

I'll try to pull it again after this make is completed.

Thanks Sebastian.
