a310acd7a7 NVMe: use split lo_hi_{read,write}q 
Some controllers may require ordered split transfers even on 64bit
machines, e.g. Apple's NVMe controller as found in the MacBook8,1 and
MacBookAir7,1 (256/512GB models).

This patch enforces ordered split transfers on 64bit platforms, which
works around that issue for all controllers. As pointed out by Christoph
[1] there should be no performance impact due to that modification.

Updated by me to explicitly use lo_hi_read/writeq instead of playing

82c426e0f1 MAINTAINERS: add reference to new linux-block list 
In the past, I've resisted doing a non-lkml related block/storage
list. But we have more activity now than we previously did, and
ain't nobody got time to track and follow lkml.

So now linux-block@vger.kernel.org exists. Please CC your patches
related to block/storage here, and we'll have an easier time
tracking them.

b12363d0a5 NVMe: Increase the max transfer size when mdts is 0 
This patch address the issue when IO with 128KB from FIO is split into
two parts, 124KB and 4KB, due to max transfer size(127KB). This degrades
the device performance.

2bcef9b457 MIPS: Make MIPS_CMDLINE_DTB default 
Seval of-enabled machines (bmips, lantiq, xlp, pistachio, ralink) copied
the arguments from dtb to arcs_command_line to prevent the kernel from
overwriting them.

Since there is now an option to keep the dtb arguments, default to the
new option remove the "backup" to arcs_command_line in case of USE_OF is
enabled, except for those platforms that still take the bootloader
arguments or do not use any at all.

2024972ef5 MIPS: Make the kernel arguments from dtb available 
Similar to how arm allows using selecting between bootloader arguments,
dtb arguments and both, allow to select them on mips. But since we have
less control over the place of the dtb do not modify it but instead use
the boot_command_line for merging them.

The default is "use bootloader arguments" to keep the current behaviour
as default.

6e80785267 MIPS: Lantiq: Fix check for return value of request_mem_region() 
request_mem_region() returns a pointer and not an integer with an error
value. A check for "< 0" on a pointer will cause problems, replace it
with not null checks instead. This was found with sparse.

95135bfa7e MIPS: Lantiq: Deactivate most of the devices by default 
When the SoC starts up most of the devices should be deactivated by the
PMU, they should be activated when they get used by their drivers. Some
devices should not get deactivate at startup like the serial, register
them in a special way.
