v4:
1. put size into the macro body (Konstantin)
2. replace assert with BUILD_BUG_ON (Stephen)
3. delete unnecessary compiler barrier for bpf (Konstantin)

v5:
1. 'size' is not the parameter (Konstantin)
2. put () around macro parameters (Konstantin)
3. fix some original typo issue (Jerin)
4. swap 'rte_wait_event' parameter location (Jerin)
5. add new macro '__LOAD_EXC'
6. delete 'undef' to prevent compilation warning

v6:
1. fix patch style check warning
2. delete 'bpf' patch due to 'const' limit

v7:
1. add __RTE_ARM to to fix the namespace (Jerin)
2. use 'uintptr_t *' in mcslock for different
architecture(32/64) (Mattias)

compiler issue
4. add bpf patch and use 'uintptr_t' to fix const
discard warning (Konstantin)

v8:

v9:
1. rename 'wait_event' as 'wait_until' (David)
2. change commit message (David)

Feifei Wang (5):
  eal: add a new generic helper for wait scheme
  pflock: use wait until scheme for read pflock
  mcslock: use wait until scheme for mcslock
  bpf: use wait until scheme for Rx/Tx iteration
