qspinlock benefits riscv. On arm64, there's nothing in

NUMA is on the way:
https://lore.kernel.org/linux-riscv/20201119003829.1282810-1-atish.pa...@wdc.com/
With your advice, I think we could using tickets lock when <= 16 CPUs
and using qspinlock when > 16 CPUs.
Is that right?
The next patchset plan is:
- Using tickets & qspinlock together in riscv. Abandon 16bits
xchg/cmpxchg implementation.
- Abanden qspinlock in csky, because it only could 4 CPUs' SMP.

ore the instruction.
arw means after read and write would happen after the instruction
So it also could be bar.brarw / bar.arw / bar.brw / bar.braw
sync means we need to wait until all instructions complete in the CPU

Hi Christoph,
I use PFN_DOWN() every where as possible and seems it's a habit
problem. So let risc-v maintainer to choose "PFN_DOW()" or
">> PAGE_SHIFT".
Also the same with "end_of_DRAM & max_low_pfn".

I agree dma_alloc_wc is necessary, and we need add another more attribute
bit in PTE: _PAGE_BUF.
Perhaps using _PAGE_BUF + _PAGE_CACHE are better then _PAGE_CONHENCY.
