[PATCH v3 0/3] clocksource/drivers/arm_global_timer: Three improvements

[Martin Blumenstingl]

These are three improvements / fixes for the arm_global_timer driver.

Changes from v2 at [1]:
- add patches 1 and 2 (which is why this is now a series instead of a
  single patch) as in the code review process more issues have been
  spotted that need fixing
- remove "psv < 0" check from patch 3 (as this check is now impossible
  as patch 2 makes the variable in question an unsigned long with a
  check for zero and returning before decrementing psv).

Changes from v1 at [0]:
- use FIELD_FIT() to check whether psv overflows the register
- update the description accordingly
