Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon:
"A pair of arm64 fixes for -rc3. The straightforward one is a fix to
our firmware calling stub, which accidentally started corrupting the
link register on machines with SVE. Since these machines don't really
exist yet, it wasn't spotted in -next.
The other fix is a revert-and-a-bit of a patch originally intended to
allow PTE-level huge mappings for the VMAP area on 32-bit PPC 8xx. A
side-effect of this change was that our pXd_set_huge() implementations
could be replaced with generic dummy functions depending on the levels
of page-table being used, which in turn broke the boot if we fail to
create the linear mapping as a result of using these functions to
operate on the pgd. Huge thanks to Michael Ellerman for modifying the
revert so as not to regress PPC 8xx in terms of functionality.
Anyway, that's the background and it's also available in the commit
message along with Link tags pointing at all of the fun.
Summary:
- Fix hang when issuing SMC on SVE-capable system due to
clobbered LR
- Fix boot failure due to missing block mappings with folded
page-table"
