Since one of the platforms (Armada 370 RD) is now using the gpio-fan
driver, it makes sense to enable it in mvebu_v7_defconfig.

For some reason, while all other features are configured built-in, the
LED class support was configured as a module in
mvebu_v7_defconfig. This commit makes it consistent with the other
options, by making this feature built-in.

Many boards share the cpufreq-cpu0 driver meaning that if we enable it in
multi_v7_defconfig we can get a reasonable amount of functional utility for
systems and test coverage for a fairly small increase in kernel size.

This defconfig contains the CONFIG_M25P80 symbol, which is now

At the same time, drop the now-nonexistent CONFIG_MTD_CHAR symbol.

This is a squashed series from Soren:

"I went through the defconfig and searched for Zynq drivers. The result
is this series of patches. The first few are all for Zynq and pretty
much straight forward. The second half is mostly soft-IP, I think. That
soft-IP works with Zynq devices, but I'm not sure whether those should
go into the multi_v7 defconfig."

It seems that when a PCI Express bridge is not in use and has no devices
behind it, the ranges property is bogus.  Specifically the size property
is of the form [0xffffffff:...], and if you add this size to the resource
start address the 64-bit calculation will overflow.

Just check specifically for this size value signature and skip them.

On ppc64 we support 4K hash pte with 64K page size. That requires
us to track the hash pte slot information on a per 4k basis. We do that
by storing the slot details in the second half of pte page. The pte bit
_PAGE_COMBO is used to indicate whether the second half need to be
looked while building real_pte. We need to use read memory barrier while
doing that so that load of hidx is not reordered w.r.t _PAGE_COMBO
check. On the store side we already do a lwsync in __hash_page_4K

As per ISA, for 4k base page size we compare 14..65 bits of VA specified
with the entry_VA in tlb. That implies we need to make sure we do a
tlbie with all the possible 4k va we used to access the 16MB hugepage.
With 64k base page size we compare 14..57 bits of VA. Hence we cannot
ignore the lower 24 bits of va while tlbie .We also cannot tlb
invalidate a 16MB entry with just one tlbie instruction because
we don't track which va was used to instantiate the tlb entry.

If we changed base page size of the segment, either via sub_page_protect
or via remap_4k_pfn, we do a demote_segment which doesn't flush the hash
table entries. We do a lazy hash page table flush for all mapped pages
in the demoted segment. This happens when we handle hash page fault for
these pages.

We use _PAGE_COMBO bit along with _PAGE_HASHPTE to indicate whether a
pte is backed by 4K hash pte. If we find _PAGE_COMBO not set on the pte,
that implies that we could possibly have older 64K hash pte entries in
the hash page table and we need to invalidate those entries.

Use _PAGE_COMBO to determine the page size with which we should
invalidate the hash table entries on unmap.
