GICR for multiple CPU can be described with start address and stride,
or with multiple address. Current multiple address and stride are
both used. Fix it.

vmalloc patch 727a7f5a9 triggered this bug:

A Fixes: tag would be useful on a patch like this, to tell what patch
introduced the problem. Please consider using them in the future.

I've applied this one to fixes now.

Hi Olof,

I happened to still have this one in my todo folder as I must have
missed your reply, and I stumbled over it while looking for things
that may have gone missing.

I don't see it in v4.9-rc6, did it get dropped accidentally?

Please help get this into v4.9 if possible, as it is required to get
v4.9 kernel boot up on ZTE ZX296718 SoC.  Thanks.

Shawn

Ok, applied both. Thanks,

Patch 2/2 already went to you in the pull request[1]:

[GIT PULL] ZTE arm64 device tree updates for 4.10
