v3: Fix headline format error.
v2: Rebase and modify the rwlock test case to address the comments in v1.
v1: Reimplement rwlock with atomic builtins, and add a rwlock perf test
on all available cores to benchmark the improvement.
We tested the patches on three arm64 platforms.
ThundeX2 gained 20% performance, Qualcomm gained 36% and
the 4-Cortex-A72 Marvell MACCHIATObin gained 19.6%.
Below is the detailed test result on ThunderX2:
*** rwlock_autotest without atomic builtins ***
Rwlock Perf Test on 128 cores...
Core [0] count = 281
Core [1] count = 252
Core [2] count = 290
Core [3] count = 259
Core [4] count = 287
...
Core [209] count = 3
Core [210] count = 31
Core [211] count = 120
Total count = 18537
*** rwlock_autotest with atomic builtins ***
Rwlock Perf Test on 128 cores...
Core [0] count = 346
Core [1] count = 355
Core [2] count = 259
Core [3] count = 285
Core [4] count = 320
...
Core [209] count = 2
Core [210] count = 23
Core [211] count = 63
Total count = 22194
