h8300 is a nommu architecture and does not require fixup for upper layers
of the page tables because it is already handled by the generic nommu
implementation.
Remove definition of __ARCH_USE_5LEVEL_HACK in
arch/h8300/include/asm/pgtable.h

The hexagon architecture has 2 level page tables and as such most of the
page table folding is already implemented in asm-generic/pgtable-nopmd.h.
Fixup the only place in arch/hexagon to unfold the p4d level and remove
__ARCH_USE_5LEVEL_HACK.

Hi,
These patches convert several architectures to use page table folding and
remove __ARCH_HAS_5LEVEL_HACK along with include/asm-generic/5level-fixup.h.
The changes are mostly about mechanical replacement of pgd accessors with p4d
ones and the addition of higher levels to

The unicore32 architecture has 2 level page tables and
asm-generic/pgtable-nopmd.h and explicit casts from pud_t to pgd_t for page
table folding.
Add p4d walk in the only place that actually unfolds the pud level and
remove __ARCH_USE_5LEVEL_HACK.

The __pXd_offset() macros are identical to the pXd_index() macros and there
is no point to keep both of them. All architectures define and use
pXd_index() so let's keep only those to make mips consistent with the rest
of the kernel.

I don't think it is worth adding all this additionnals walks of p4d,

Let's not pretend we support anything but ARMv8.0 as far as the
debug architecture is concerned.

Here's a few cleanups and fixes for 5.6, all around our debug and
PMU ID register emulation:
1) Missing RES1 bit in DBGDIDR
2) Limiting PMU version to v8.1
3) Limiting debug version to ARMv8.0
4) Support for ARMv8.4-PMU
(1) was reported by Peter, (2) had a patch from Andrew Murray on the
list, bu
The AArch32 CP14 DBGDIDR has bit 15 set to RES1, which our current
emulation doesn't set. Just add the missing bit.

Our PMU code is only implementing the ARMv8.1 features, so let's
stick to this when reporting the feature set to the guest.

Our current ID register filtering is starting to be a mess of if()
statements, and isn't going to get any saner.
Let's turn it into a switch(), which has a chance of being more
readable.

Upgrading the PMU code from ARMv8.1 to ARMv8.4 turns out to be
pretty easy. All that is required is support for PMMIR_EL1, which
is read-only, and for which returning 0 is a valid option.
Let's just do that and adjust what we return to the guest.
