bcache: Fix building error on MIPS

2017-12-05T10:24:34+00:00

commit cf33c1ee5254c6a430bc1538232b49c3ea13e613 upstream.

This patch try to fix the building error on MIPS. The reason is MIPS
has already defined the PTR macro, which conflicts with the PTR macro
in include/uapi/linux/bcache.h.

mm, hugetlbfs: introduce ->split() to vm_operations_struct

2017-12-05T10:24:32+00:00

commit 31383c6865a578834dd953d9dbc88e6b19fe3997 upstream.

Patch series "device-dax: fix unaligned munmap handling"

When device-dax is operating in huge-page mode we want it to behave like
hugetlbfs and fail attempts to split vmas into unaligned ranges.  It
would be messy to teach the munmap path about device-dax alignment
constraints in the same (hstate) way that hugetlbfs communicates this
constraint.  Instead, these patches introduce a new ->split() vm
operation.

This patch (of 2):

The device-dax interface has similar constraints as hugetlbfs in that it
requires the munmap path to unmap in huge page aligned units.  Rather
than add more custom vma handling code in __split_vma() introduce a new
vm operation to perform this vma specific check.

SUNRPC: Fix tracepoint storage issues with svc_recv and svc_rqst_status

commit e9d4bf219c83d09579bc62512fea2ca10f025d93 upstream.

There is no guarantee that either the request or the svc_xprt exist
by the time we get round to printing the trace message.

mm/page_alloc.c: broken deferred calculation

2017-11-24T07:33:42+00:00

commit d135e5750205a21a212a19dbb05aeb339e2cbea7 upstream.

In reset_deferred_meminit() we determine number of pages that must not
be deferred.  We initialize pages for at least 2G of memory, but also
pages for reserved memory in this node.

The reserved memory is determined in this function:
memblock_reserved_memory_within(), which operates over physical
addresses, and returns size in bytes.  However, reset_deferred_meminit()
assumes that that this function operates with pfns, and returns page
count.

The result is that in the best case machine boots slower than expected
due to initializing more pages than needed in single thread, and in the
worst case panics because fewer than needed pages are initialized early.

netfilter/ipvs: clear ipvs_property flag when SKB net namespace changed

2017-11-24T07:33:40+00:00

[ Upstream commit 2b5ec1a5f9738ee7bf8f5ec0526e75e00362c48f ]

When run ipvs in two different network namespace at the same host, and one
ipvs transport network traffic to the other network namespace ipvs.
'ipvs_property' flag will make the second ipvs take no effect. So we should
clear 'ipvs_property' when SKB network namespace changed.

ARM: dts: Fix omap3 off mode pull defines

2017-11-21T08:23:22+00:00

[ Upstream commit d97556c8012015901a3ce77f46960078139cd79d ]

We need to also have OFFPULLUDENABLE bit set to use the off mode pull values.
Otherwise the line is pulled down internally if no external pull exists.

This is has some documentation at:

http://processors.wiki.ti.com/index.php/Optimizing_OMAP35x_and_AM/DM37x_OFF_mode_PAD_configuration

Note that the value is still glitchy during off mode transitions as documented
in spz319f.pdf "Advisory 1.45". It's best to use external pulls instead of
relying on the internal ones for off mode and even then anything pulled up
will get driven down momentarily on off mode restore for GPIO banks other
than bank1.

target/iscsi: Fix iSCSI task reassignment handling

commit 59b6986dbfcdab96a971f9663221849de79a7556 upstream.

Allocate a task management request structure for all task management
requests, including task reassignment. This change avoids that the
se_tmr->response assignment dereferences an uninitialized se_tmr
pointer.
