The sw2iso count should cover ARM LDO ramp-up time, the MAX ARM LDO ramp-up time may be up to more than 100us on some boards, this patch sets sw2iso to 0xf (~384us) which is the reset value, and it is much more safe to cover different boards, since we have observed that some customer boards failed with current setting of 0x2.

2018-12-05mm, thp: restore node-local hugepage allocationsDavid Rientjes
This is a full revert of ac5b2c18911f ("mm: thp: relax __GFP_THISNODE for MADV_HUGEPAGE mappings") and a partial revert of 89c83fb539f9 ("mm, thp: consolidate THP gfp handling into alloc_hugepage_direct_gfpmask"). By not setting __GFP_THISNODE, applications can allocate remote hugepages when the local node is fragmented or low on memory when either the thp defrag setting is "always" or the vma has been madvised with MADV_HUGEPAGE. Remote access to hugepages often has much higher latency than local pages of the native page size. On Haswell, ac5b2c18911f was shown to have a 13.9% access regression after this commit for binaries that remap their text segment to be backed by transparent hugepages. The intent of ac5b2c18911f is to address an issue where a local node is low on memory or fragmented such that a hugepage cannot be allocated. In every scenario where this was described as a fix, there is abundant and unfragmented remote memory available to allocate from, even with a greater access latency. If remote memory is also low or fragmented, not setting __GFP_THISNODE was also measured on Haswell to have a 40% regression in allocation latency. Restore __GFP_THISNODE for thp allocations.

2018-12-05acpi/nfit: Fix user-initiated ARS to be "ARS-long" rather than "ARS-short"Dan Williams
A "short" ARS (address range scrub) instructs the platform firmware to return known errors. In contrast, a "long" ARS instructs platform firmware to arrange every data address on the DIMM to be read / checked for poisoned data. The conversion of the flags in commit d3abaf43bab8 "acpi, nfit: Fix Address Range Scrub completion tracking", changed the meaning of passing '0' to acpi_nfit_ars_rescan(). Previously '0' meant "not short", now '0' is ARS_REQ_SHORT. Pass ARS_REQ_LONG to restore the expected scrub-type behavior of user-initiated ARS sessions.

2018-12-05libnvdimm, pfn: Pad pfn namespaces relative to other regionsDan Williams
Commit cfe30b872058 "libnvdimm, pmem: adjust for section collisions with 'System RAM'" enabled Linux to workaround occasions where platform firmware arranges for "System RAM" and "Persistent Memory" to collide within a single section boundary. Unfortunately, as reported in this issue [1], platform firmware can inflict the same collision between persistent memory regions. The approach of interrogating iomem_resource does not work in this case because platform firmware may merge multiple regions into a single iomem_resource range. Instead provide a method to interrogate regions that share the same parent bus. This is a stop-gap until the core-MM can grow support for hotplug on sub-section boundaries.

2018-12-05media: Add a Kconfig option for the Request APISakari Ailus
The Request API is now merged to the kernel but the confidence on the stability of that API is not great, especially regarding the interaction with V4L2. Add a Kconfig option for the API, with a scary-looking warning. The patch itself disables request creation as well as does not advertise them as buffer flags. The driver requiring requests (cedrus) now depends on the Kconfig option as well.

2018-12-05media: mpeg2-ctrls.h: move MPEG2 state controls to non-public headerHans Verkuil
The MPEG2 state controls for the cedrus stateless MPEG2 driver are not yet stable. Move them out of the public headers into media/mpeg2-ctrls.h. Eventually, once this has stabilized, they will be moved back to the public headers. Unfortunately I had to cast the control type to a u32 in two switch statements to prevent a compiler warning about a control type define not being part of the enum.

2018-12-05i3c: master: dw: fix mask operation by using the correct operatorColin Ian King
The masking operation on status is using a bitwise 'or' rather than a bitwise 'and' operator, and hence the result is always non-zero which is probably not what is intended. Fix this by using the correct operator.
