Let's zero-extend hardware id number when forming firmware file name,
to avoid kernel requesting firmware like "elants_i2c_ 0.bin", which
is quite unexpected.

Pull final removal of deprecated cpus_* cpumask functions from Rusty Russell:
"This is the final removal (after several years!) of the obsolete

Yes, it should work, but it's a bad idea. Not only did ARM64 not have
the 16-bit access code (there's a separate patch to add it), it's just
not a good atomic type. Some architectures fundamentally don't do
atomic accesses in them (alpha), and it's not like it saves any space
here anyway because of structure packing issues.
We normally should aim for flags to be "unsigned int" or "unsigned
long". And if space is at a premium, use a single byte (although that
causes problems on alpha again). There might be very special cases
where a 16-byte entity is really wanted, but this is not one of them.

Only Intel Haswell and Broadwell have a separate HD-A controller (PCI device 3)
for display audio, which needs to get 24MHz HD-A link BCLK from the variable
display core clock through vendor specific registers EM4 & EM5. Other platforms
(Baytrail, Braswell and Skylake) don't have this feature.
So this patch checks the PCI device ID of the controller in haswell_set_bclk()
and only sync BCLK for HSW and BDW.

The initial version of TCMU (in 3.18) does not properly handle
bidirectional SCSI commands -- those with both an in and out buffer. In
looking to fix this it also became clear that TCMU's support for adding
new types of entries (opcodes) to the command ring was broken. We need
to fix this now, so that future issues can be handled properly by adding
new opcodes.
We make the most of this ABI break by enabling bidi cmd handling within
TCMP_OP_CMD opcode. Add an iov_bidi_cnt field to tcmu_cmd_entry.req.
This enables TCMU to describe bidi commands, but further kernel work is
needed for full bidi support.
Enlarge tcmu_cmd_entry_hdr by 32 bits by pulling in cmd_id and __pad1. Turn
__pad1 into two 8 bit flags fields, for kernel-set and userspace-set flags,
"kflags" and "uflags" respectively.
Update version fields so userspace can tell the interface is changed.
Update tcmu-design.txt with details of how new stuff works:
- Specify an additional requirement for userspace to set UNKNOWN_OP
(bit 0) in hdr.uflags for unknown/unhandled opcodes.
- Define how Data-In and Data-Out fields are described in req.iov[]
Changed in v2:
- Change name of SKIPPED bit to UNKNOWN bit
- PAD op does not set the bit any more
- Change len_op helper functions to take just len_op, not the whole struct
- Change version to 2 in missed spots, and use defines
- Add 16 unused bytes to cmd_entry.req, in case additional SAM cmd
parameters need to be included
- Add iov_dif_cnt field to specify buffers used for DIF info in iov[]
- Rearrange fields to naturally align cdb_off
- Handle if userspace sets UNKNOWN_OP by indicating failure of the cmd
- Wrap some overly long UPDATE_HEAD lines
(Add missing req.iov_bidi_cnt + req.iov_dif_cnt zeroing - Ilias)
