[PATCH v3 0/1] arm64: ptrace: fix hw_break_set() to set addr and ctrl together

[Bill Tsui]

After revisiting my patches a few weeks later, I have some additional
thoughts:

  1. Keep arm32 ptrace as it. Legacy APIs only need critical bug fix.
  2. For arm64 ptrace, the patch is not only a fix for 32-bit tracee
     but also a refactor that removes partially set state, making logic
	 clearer and preventing similar bugs.

The patch can be tested with the code in my previous mail:
