linux-next: manual merge of the tmem tree with the xen-two tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 474 bytes --]

Hi Dan,

Today's linux-next merge of the tmem tree got a conflict in
drivers/xen/Kconfig drivers/xen/tmem.c between commit afec6e04922d ("xen:
prepare tmem shim to handle frontswap") from the xen-two tree and commit
ac33c46b42ba ("xen: enable frontswap for Xen tmem") from the tmem tree.

I just used the xen-two versions of these files (as they look newer).

Dan, can you please rebase your #linux-next branch on my #linux-next branch
so that Stephen's awesome build engine can chug along for this?

Thanks!

OK, we will sort this out.

Should hopefully all be fixed now.  (Konrad's version of the commit is
indeed the newer version so I have removed the older version from the
tmem tree.)

Thanks,
Dan

Oh, my. That is a mistake. I've reseted the #linux-next to be 3.7-rc3
in the tmem tree. It was not suppose to have that patch and I think
I just did 'git am' on the wrong tree. Thanks for catching this!

Just to be sure, the tmem tree is

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/mm.git#linux-next

The version of the tmem tree I have has commit a728d5ea1c20 as its head
and has the shortlog below.  I has not changed since Sept 24.

$ git shortlog origin/master..tmem/linux-next

Thank you.

I am not really sure how this happen - the 'tmem' tree should not have
had 7282a68f5aea, and more interestingly, I cannot find it in the
tmem tree! Either way, let me just reset the #linux-next to v3.7-rc3
in tmem tree and see if this shows up.

linux-next: manual merge of the tmem tree with the xen-two tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 569 bytes --]

Hi Konrad,

Today's linux-next merge of the tmem tree got a conflict in
arch/x86/xen/smp.c between commits 1ba23a0f2605 ("xen/smp: Move the
common CPU init code a bit to prep for PVH patch") and 6c6067f26388
("xen/pvh: Extend vcpu_guest_context, p2m, event, and XenBus") from the
xen-two tree and commit 7282a68f5aea ("PVH: Basic and preparatory
changes") from the tmem tree.

I fixed it up (using the xen-two tree version) and can carry the fix as
necessary (no action is required).

Hi Konrad,

Today's linux-next merge of the tmem tree got a conflict in
arch/x86/xen/setup.c between commit 6056726e851a ("xen/pvh: bootup and
setup (E820) related changes") from the xen-two tree and commit
7282a68f5aea ("PVH: Basic and preparatory changes") from the tmem tree.

I fixed it up (by using the xen-two tree version) and can carry the fix
as necessary (no action is required).

Hi Konrad,

Today's linux-next merge of the tmem tree got conflicts in

I fixed it up (see below and using the xen-two version for cpu_hotplug.c)
