Subject: [PATCH 0/3] Fix preemption errors in watchpoints
Date: Tue, 29 Aug 2023 16:34:54 +1000 [thread overview]
Message-ID: <20230829063457.54157-1-bgray@linux.ibm.com> (raw)
When enabling debug config options relating to preemption, several bugs
appear in the kernel log. With this series applied, the breakpoint code
no longer prints bugs when running the powerpc/ptrace selftests.
Benjamin Gray (3):
powerpc/watchpoints: Disable preemption in thread_change_pc()
powerpc/watchpoint: Disable pagefaults when getting user instruction
powerpc/watchpoints: Annotate atomic context in more places
