Changes in V14:
---------------
- Remove duplicated NT_PPC_xxx register macro in
tools/testing/selftests/powerpc/ptrace/ptrace.h
- Clean some coding style warning
Changes in V13:
---------------
- Remove Cc lines from changelog
- Add more Signed-off-by lines of Simon Guo
Changes in V12:
---------------
- Revert change which is trying to incoporate following patch:
[PATCH 3/5] powerpc: tm: Always use fp_state and vr_state to store live registers
- Release share memory resource in all self test cases
- Optimize tfhar usage in ptrace-tm-spr.c
Changes in V11:
---------------
- Rework based on following patch:
[PATCH 3/5] powerpc: tm: Always use fp_state and vr_state to store live registers
- Split EBB/PMU register ptrace implementation.
- Clean some coding style warning
- Added more shared memory based sync between parent and child during TM tests
- Re worded some of the commit messages and cleaned them up
- selftests/powerpc/ebb/reg.h has already moved as selftests/powerpc/reg.h
Dropped the previous patch doing the same thing
- Combined the definitions of SPRN_DSCR from dscr/ test cases
- Fixed dscr/ test cases for new SPRN_DSCR_PRIV definition available
Changes in V10:
---------------
- Rebased against the latest mainline
- Fixed couple of build failures in the test cases related to aux vector
Changes in V9:
--------------
- Fixed static build check failure after tm_orig_msr got dropped
- Fixed asm volatile construct for used registers set
- Fixed EBB, VSX, VMX tests for LE
- Fixed TAR test which was failing because of system calls
- Added checks for PPC_FEATURE2_HTM aux feature in the tests
- Fixed copyright statements
Changes in V8:
--------------
- Split the misc register set into individual ELF core notes
- Implemented support for VSX register set (on and off TM)
- Implemented support for EBB register set
- Implemented review comments on previous versions
- Some code re-arrangements, re-writes and documentation
- Added comprehensive list of test cases into selftests
Changes in V7:
--------------
- Fixed a config directive in the MISC code
- Merged the two gitignore patches into a single one
Changes in V6:
--------------
- Added two git ignore patches for powerpc selftests
- Re-formatted all in-code function definitions in kernel-doc format
Changes in V5:
--------------
- Changed flush_tmregs_to_thread, so not to take into account self tracing
- Dropped the 3rd patch in the series which had merged two functions
- Fixed one build problem for the misc debug register patch
- Accommodated almost all the review comments from Suka on the 6th patch
- Minor changes to the self test program
- Changed commit messages for some of the patches
Changes in V4:
--------------
- Added one test program into the powerpc selftest bucket in this regard
- Split the 2nd patch in the previous series into four different patches
- Accommodated most of the review comments on the previous patch series
- Added a patch to merge functions __switch_to_tm and tm_reclaim_task
Changes in V3:
--------------
- Added two new error paths in every TM related get/set functions when regset
support is not present on the system (ENODEV) or when the process does not
have any transaction active (ENODATA) in the context
- Installed the active hooks for all the newly added regset core note
types
Changes in V2:
--------------
- Removed all the power specific ptrace requests corresponding to new
NT_PPC_*
elf core note types. Now all the register sets can be accessed from
ptrace
through PTRACE_GETREGSET/PTRACE_SETREGSET using the individual
NT_PPC* core
note type instead
- Fixed couple of attribute values for REGSET_TM_CGPR register set
- Renamed flush_tmreg_to_thread as flush_tmregs_to_thread
- Fixed 32 bit checkpointed GPR support
- Changed commit messages accordingly
