Assert that we're not seeing large pages in functions that read/write
inline data, rather than zeroing out the tail.

We can only kmap() one subpage of a THP at a time, so loop over all
relevant subpages, skipping ones which don't need to be zeroed. This is
too large to inline when THPs are enabled and we actually need highmem,
so put it in highmem.c.

If the page is compound, check the last index in the page and return
the appropriate size. Change the return type to ssize_t in case we ever
support pages larger than 2GB.

Size the uptodate array dynamically. Now that this array is protected
by a spinlock, we can use bitmap functions to set the bits in this array
instead of a loop around set_bit().

This helper is useful for both large pages in the page cache and for
supporting block size larger than page size. Convert some example
users (we have a few different ways of writing this idiom).

Hi Dave,
this series moves the compat_ioctl handlers into the protocol handlers,
avoiding the need to override the address space limited as in the current
handler.
Changes since v1:
- reorder a bunch of variable declarations
To prepare removing the global routing_ioctl hack start lifting the code
into the ipv4 and appletalk ->compat_ioctl handlers. Unlike the existing
handler we don't bother copying in the name - there are no compat issues for
char arrays.

Mirroring offset_in_page(), this gives you the offset within this
particular page, no matter what size page it is. It optimises down
to offset_in_page() if CONFIG_TRANSPARENT_HUGEPAGE is not set.

Hello!
There is inconsistency in firmware naming for W8997 SDIO wifi chip.
Firmware for this chip is stored in linux-firmware [1] repository under
filename sdsd8997_combo_v4.bin.
But mainline linux kernel driver mwifiex_sdio.ko [2] expects and loads
firmware for this chip from filename sd8997_ua

Hi Sebastian,
I've left a few trivial suggestions, although I suspect only one of them
really matters. Namely - I think as-is the code changes the legacy behaviour
when OF is missing.
Mind you, this is my third time skimming through power/supply, so take it with
a grain of salt.
