[0/9] KVM: arm64: selftests: Test linked {break,watch}points

Message

Reiji Watanabe Aug. 25, 2022, 5:08 a.m. UTC

This series adds test cases for linked {break,watch}points to the
debug-exceptions test, and expands {break,watch}point tests to
use non-zero {break,watch}points (the current test always uses
{break,watch}point#0).

Patches 1-6 add some helpers or do minor refactoring for
preparation of adding test cases in subsequent patches.
Patches 7-8 add test cases for a linked {break,watch}point.
Patch 9 expands {break,watch}point test cases to use non-zero
{break,watch}points.
