* Idea:
Intel Data Streaming Accelerator(DSA) is introduced in Intel's 4th generation
Xeon server, aka Sapphire Rapids.
https://01.org/blogs/2019/introducing-intel-data-streaming-accelerator
One of the things DSA can do is to offload memory comparison workload from
CPU to DSA accelerator hardware
1. Adds a memory comparison function by submitting
the work to the idxd driver.
2. Add interface to set bufferiszero accel function
to DSA offloading.
3. Fallback to use CPU accel function if DSA offloading
fails due to page fault.

Idxd is the device driver for DSA (Intel Data Streaming
Accelerator). The driver is fully functioning since Linux
kernel 5.19. This change adds the driver's header file used
for userspace development.

The tlb index and entry are often retrieved together and tlb_entry()
already calls tlb_index() so it could easily return it. Add a
tlb_index_and_entry() function that does that to simplify callers and
maybe avoid some duplicate calculations.
