[GIT PULL] arm64: Fixes for -rc1

[Will Deacon]

Hi Linus,

We've had a few arm64 fixes trickle in this week, so please can you pick
them up for -rc1? Nothing catastophic, but all things that should be
addressed.

Cheers,

Will

Sorry, failed to read your commentary at the top. I suppose all this
is fine. It would be nice to have a chance to see all this before it
gets sent upstream.

I've commented on the patch, but this doesn't fix anything. The original 
work-around was fine.

[GIT PULL] arm64 fixes for -rc1

[Will Deacon]

Hi Linus,

Please pull these arm64 fixes for -rc1. I think the main one is fixing
the dynamic SCS patching when full LTO is enabled (clang was silently
getting this horribly wrong), but it's all good stuff. Rob just pointed
out that the fix to the workaround for erratum #2966298 might not be
necessary, but in the worst case it's harmless and since the official
description leaves a little to be desired here, I've left it in.

Cheers,

Will

[GIT PULL] arm64 fixes for -rc1

[Will Deacon]

Hi Linus,

Please pull these three arm64 fixes for -rc1. The main one is a fix for
a broken strscpy() conversion that landed in the merge window and broke
early parsing of the kernel command line.

Cheers,

Will

Hi Linus,

Please pull these few arm64 fixes that came in during the merge window for

[GIT PULL] arm64 fixes for -rc1

[Will Deacon]

Hi Linus,

Please pull these two arm64 fixes for -rc1, fixing issues introduced by
the recent pull for 6.2. They're both straightforward: a Kconfig tweak
and a revert. Summary in the tag.

There are some other fixes kicking around, but they're not urgent at all
(things like benign sparse warnings) so I'll get back to them in the new
year.

Cheers,

Will

arm64 fixes for -rc1

- Fix Kconfig dependencies to re-allow the enabling of function graph

- Revert the workaround for CPU erratum #2645198 since the CONFIG_

[GIT PULL] arm64: Fixes for -rc1

[Will Deacon]

Hi Linus,

Please pull these arm64 fixes for -rc1. The big one is a fix for the VHE
enabling path during early boot, where the code enabling the MMU wasn't
necessarily in the identity map of the new page-tables, resulting in a
consistent crash with 64k pages. In fixing that, we noticed some missing
barriers too, so we added those for the sake of architectural compliance.

Other than that, just the usual merge window trickle. There'll be more
to come, too.

Cheers,

Will

Hi Linus,

Given that my availability next week is likely to be poor, here are three
arm64 fixes to resolve some issues introduced by features merged last
week. I was going to wait until -rc1, but it doesn't make much sense to
sit on fixes. Please pull.

Thanks,
