[GIT PULL] libnvdimm-fixes for 4.5-rc2
by Williams, Dan J
Hi Linus, please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm libnvdimm-fixes
1/ Fixes to the libnvdimm 'pfn' device that establishes a reserved area
for storing a struct page array.
2/ Fixes for dax operations on a raw block device to prevent pagecache
collisions with dax mappings.
3/ A fix for pfn_t usage in vm_insert_mixed that lead to a null pointer
de-reference.
These have received build success notification from the kbuild robot
across 153 configs and pass the latest ndctl tests.
Note that the below commits are also in -mm, but as Andrew is offline
until tomorrow I thought it best to submit these for 4.5-rc2
consideration. Please yell if I should just wait next time:

devm_memremap_pages: fix vmem_altmap lifetime + alignment handling
to_vmem_altmap() needs to return valid results until
arch_remove_memory() completes. It also needs to be valid for any pfn
in a section regardless of whether that pfn maps to data. This escape
was a result of a bug in the unit test.
The signature of this bug is that free_pagetable() fails to retrieve a
vmem_altmap and goes off into the weeds:

fs, block: force direct-I/O for dax-enabled block devices
Similar to the file I/O path, re-direct all I/O to the DAX path for I/O
to a block-device special file. Both regular files and device special
files can use the common filp->f_mapping->host lookup to determing is
DAX is enabled.
Otherwise, we confuse the DAX code that does not expect to find live
data in the page cache:

block: revert runtime dax control of the raw block device
Dynamically enabling DAX requires that the page cache first be flushed
and invalidated. This must occur atomically with the change of DAX mode
otherwise we confuse the fsync/msync tracking and violate data
durability guarantees. Eliminate the possibilty of DAX-disabled to
DAX-enabled transitions for now and revisit this for the next cycle.

mm: fix pfn_t to page conversion in vm_insert_mixed
pfn_t_to_page() honors the flags in the pfn_t value to determine if a
pfn is backed by a page. However, vm_insert_mixed() was originally
written to use pfn_valid() to make this determination. To restore the
old/correct behavior, ignore the pfn_t flags in the !pfn_t_devmap() case
and fallback to trusting pfn_valid().

[PATCH 0/3] libnvdimm: fix memmap in pmem support
by Dan Williams
Thanks to Jeff for pointing out a thinko in the ndctl implementation of
create-namespace. That bug was covering up the fact that vmem_altmap
handling broke when 'pgmap_radix' was introduced to replace the list
based method [1].
The other two fixes fell out from further expanding the unit tests.

[PATCH 0/2] block: fix raw block device dax support
by Dan Williams
The dax support for a raw block device did not account for page cache
entries established by the kernel for partition reads. This breaks dax
as it assumes that page cache entries are limited to covering holes in
files, or are exceptional entries marking dirty pages.
Additionally, the facility to toggle dax at runtime fails to handle
evacuating the page cache when switching from non-dax-mode to dax-mode.
It needs to be rethought as enabling dax needs to be atomic with
flushing the page cache.

[ndctl PATCH 00/13] ndctl: namespace creation, listing, and misc fixes
by Dan Williams
This series finalizes the work that has been brewing on the 'pending'
branch of the ndctl repository. It includes:
1/ Support for 'pfn' configurations to allocate an memmap array (struct
page) for a pmem namespace and enable direct-I/O + DMA.
2/ Reference implementations for namespace creation and lisitng devices
via the new 'ndctl create-namespace' and 'ndctl list' commands. Note
these are reference commands as the recommended vendor-provided tooling
should be used where available.
3/ Various fixes identified by the new unit tests and static analysis
checkers.
