Defaulting to scsi-mq in 4.13-rc has shown various regressions
on setups that we didn't previously consider. Fixes for them are
in progress, but too invasive to make it in this cycle. So for
now revert the commit that defaults to blk-mq for SCSI. For 4.14
we'll plan to try again with these fixes.
This reverts commit 5c279bd9e4.

Releasing a zone write lock only when the write commnand that acquired
the lock completes can cause deadlocks due to potential command
reordering if the lock owning request is requeued and not executed. This
problem exists only with the scsi-mq path as, unlike the legacy path,
requests are moved out of the dispatch queue before being prepared and
so before locking a zone for a write command.
Since sd_uninit_cmnd() is now always called when a request is requeued,
call sd_zbc_write_unlock_zone() from that function for write requests
that acquired a zone lock instead of from sd_done(). Acquisition of a zone
lock by a write command is indicated using the new command
flag SCMD_ZONE_WRITE_LOCK.

Changes in this pull request are around catching up
cros_ec with the internal chromeos-kernel versions of
cros_ec, cros_ec_lpc, and cros_ec_lightbar.
Also, switching maintainership from olof to bleung.

...
When building the argv/envp pointers, the envp is needlessly
pre-incremented instead of just continuing after the argv pointers are
finished. In some (likely impossible) race where the strings could be
changed from userspace between copy_strings() and here, it might be
possible to confuse the envp position. Instead, just use sp like
everything else.

Now that explicitly executed loaders are loaded in the mmap region, we
have more freedom to decide where we position PIE binaries in the
address space to avoid possible collisions with mmap or stack regions.
For 64-bit, align to 4GB to allow runtimes to use the entire 32-bit
address space for 32-bit pointers. On 32-bit use 4MB, which is the
traditional x86 minimum load location, likely to avoid historically
requiring a 4MB page table entry when only a portion of the first 4MB
would be used (since the NULL address is avoided). For s390 the
position could be 0x10000, but that is needlessly close to the NULL
address.
