The sun4i DMA engine supports transfer sizes up to 128k for normal DMA
and 16M for dedicated DMA, as documented in the A10 and A20 manuals.

Since this is larger than the default segment size limit (64k), exposing
the real limit reduces the number of transfers needed for a transaction.
However, because the device can only report one segment size limit, we
have to expose the smaller limit from normal DMA.

One complication is that the driver combines pairs of periodic transfers
to reduce programming overhead. This only works when the period size is
at most half of the maximum transfer size. With the default 64k segment
size limit, this was always the case, but for normal DMA it is no longer
guaranteed. Skip the optimization if the period is too long; even
without it, the overhead is less than before.

  delayacct: track delays from write-protect copy

The bluetooth code uses our bitmap infrastructure for the two bits (!)
of connection setup flags, and in the process causes odd problems when
it converts between a bitmap and just the regular values of said bits.

It's completely pointless to do things like bitmap_to_arr32() to convert
a bitmap into a u32.  It shoudln't have been a bitmap in the first
place.  The reason to use bitmaps is if you have arbitrary number of
bits you want to manage (not two!), or if you rely on the atomicity
guarantees of the bitmap setting and clearing.

The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
clear the bit values, but considering that it then copies the bitmaps
around with "bitmap_to_arr32()" and friends, there clearly cannot be a
lot of atomicity requirements.

So just use a regular integer.

In the process, this avoids the warnings about erroneous use of
bitmap_from_u64() which were triggered on 32-bit architectures when
conversion from a u64 would access two words (and, surprise, surprise,
only one word is needed - and indeed overkill - for a 2-bit bitmap).

That was always problematic, but the compiler seems to notice it and
warn about the invalid pattern only after commit 0a97953f ("lib: add
bitmap_{from,to}_arr64") changed the exact implementation details of
'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.
