Hi Linus,
Found a couple of brown paper bag bugs with the prev pull request (including a
SMP
build breakage report from Guenter). Since these are urgent I also decided to
send
over a bunch of other pending fixes which could have otherwise waited an rc or
two. Please pull.
Thx,

The function __arch_wb_cache_pmem() was already an internal implementation

Introduce pgoff_mkclean() which conceptually is similar to page_mkclean()
except it works in the absence of struct page and it can also be used to

pgoff_mkclean() doesn't return an error for a missing PTE/PMD when looping
through the VMAs
To properly handle fsync/msync in an efficient way DAX needs to track dirty
pages so it is able to flush them durably to media on demand.
The tracking of dirty pages is done via the radix tree in struct
