ADMA2 64-bit addressing support is divided into V3 mode and V4 mode.
So there are two kinds of descriptors for ADMA2 64-bit addressing
i.e. 96-bit Descriptor for V3 mode, and 128-bit Descriptor for V4
mode. 128-bit Descriptor is aligned to 8-byte.
For V4 mode, ADMA2 64-bit addressing is enabled

The host buffer depth is hardware specific so it's better to
handle it inside the me and txe hw modules. In me the depth
is read from register in txe it's a constant number.
The value is now retrieved via mei_hbuf_depth accessor,
while it replaces mei_hbuf_max_len.

It seems PTI is now in -next. I'll test that soon.

init_ohci1394_wait_for_busresets() and
init_ohci1394_reset_and_init_dma() are never called in atomic context.
They call mdelay() to busily wait, which is not necessary.
mdelay() can be replaced with msleep().
This is found by a static analysis tool named DCNS written by myself.

Sure, but isn't that a bit misleading? It will have been visible since
some unknown point in time between waking up
The selftest tool tests the vDSO functions for calling the instructions
including movdiri32, movdiri64, movdir64b, umonitor, umwait, tpause,
and their support checking.
Limited by testing environment, the selftest doesn't contain some
complex tests e.g. wake up process by writing the monitor
MOVDIRI moves doubleword or quadword from register to memory through
direct store which is implemented by using write combining (WC) for
writing data directly into memory without caching the data.
Programmable agents can handle streaming offload (e.g. high speed packet
processing in network).
UMONITOR, UMWAIT, and TPAUSE are a set of user wait instructions.
UMONITOR arms address monitoring hardware using an address. A store
to an address within the specified address range triggers the
monitoring hardware to wake up the processor waiting in umwait.
UMWAIT instructs the processor to

MOVDIR64B moves 64-bytes as direct-store with 64-bytes write atomicity.
Direct store is implemented by using write combining (WC) for writing

A few new instructions including direct stores (movdiri and movdir64b)
and user wait (umwait, umonitor, and tpause) and IA32_MWAIT_CONTROL MSR to
control umwait/umonitor/tpause behaviors will be available in Tremont and
other future x86 processors.

Encrypted keys can use secure key-type as master key along with
trusted/user keys.
Secure key as master key uses, secure key type payload derieved
using CAAM hardware.
