Hi all,

this series switches the core block layer code and all users of the
existing bvec kmap helpers to use kmap_local_page.  Drivers that
currently use open coded kmap_atomic calls will converted in a follow
on series.

To do so a new kunmap variant is added that calls
flush_kernel_dcache_page.  I'm not entirely sure where to call
flush_dcache_page vs flush_kernel_dcache_page, so I've tried to follow
the documentation here, but additional feedback would be welcome.

Note that the ps3disk has a minir conflict with the
flush_kernel_dcache_page removal in linux-next through the -mm tree.
I had hoped that change would go into 5.14, but it seems like it is
being held for 5.15.

Applied for 5.15, thanks.
