It was a bit surprising that the device was reported to have probed just
fine, but the provider hadn't been registered.
So handle any errors when registering the provider and fail the probe
accordingly.

The order in which resources were freed in wm8994_device_exit() isn't
correct. The regulators are removed before they are disabled.
Fix it by reordering code a bit, which makes it exact opposite of

The kernel WARNs and then crashes today if wm8994_device_init() fails
after calling devm_regulator_bulk_get().
That happens because there are multiple devices involved here and the
order in which resources are freed isn't correct.
The regulators are added as children of wm8994->dev.

Slab pages can be compound, but we shouldn't threat them as THP for

For instance, ext4 uses slab pages for journal pages and we shouldn't

invalidate_inode_page() has expectation about page_count() of the page
-- if it's not 2 (one to caller, one to radix-tree), it will not be
dropped. That condition almost never met for THPs -- tail pages are
pinned to the pagevec.
Let's drop them, before calling invalidate_inode_page().

This patch modifies ext4_mpage_readpages() to deal with huge pages.
We read out 2M at once, so we have to alloc (HPAGE_PMD_NR *
blocks_per_page) sector_t for that. I'm not entirely happy with kmalloc
in this codepath, but don't see any other option.

The same four values as in tmpfs case.
Encyption code is not yet ready to handle huge page, so we disable huge
pages support if the inode has EXT4_INODE_ENCRYPT.

Adjust how we find relevant block within page and how we clear the
required part of the page.

We writeback whole huge page a time. Let's adjust iteration this way.

__ext4_block_zero_page_range() adjusted to calculate starting iblock
correctry for huge pages.
ext4_{collapse,insert}_range() requires page cache invalidation. We need
the invalidation to be aligning to huge page border if huge pages are
possible in page cache.

For huge pages we need to unmap whole range covered by the huge page.

Most of work happans on head page. Only when we need to do copy data to
userspace we find relevant subpage.
We are still limited by PAGE_SIZE per iteration. Lifting this limitation
would require some more work.

Most page cache allocation happens via readahead (sync or async), so if
we want to have significant number of huge pages in page cache we need
to find a ways to allocate them from readahead.
Unfortunately, huge pages doesn't fit into current readahead design:

For huge pages 'stop' must be within HPAGE_PMD_SIZE.
Let's use hpage_size() in the BUG_ON().
We also need to change how we calculate lblk for cluster deallocation.

As the function handles zeroing range only within one block, the
required changes are trivial, just remove assuption on page size.
