[PATCH v6 0/4] aarch64: Add support for POE2 extension

[Srinath Parvathaneni]

Changes in v5 -> v6:

The series has been rebased on the latest master.

PATCH 1/4:

* Replaced strcasecmp with strncasecmp for matching the "nb"
  string and updated the corresponding conditional logic.
* Replaced set_syntax_error with set_default_error.
* Added x0 checks to the second operand in poe2*.s tests and
  updated the associated *.d and *.l files.
* Updated the error message for NOT_BALANCED_17.

PATCH 2/4:
* Added a second #as invocation to the poe2-sysreg-1.d testcase
  and dropped poe2-sysreg-2.d.
* Updated the counter logic in poe2-sysreg-1.s using the .irp
  directive.
* Manually verified all macro expansions against the system
  registers defined in aarch64-sys-regs.def, and cross-checked
  the output with Clang.

PATCH 3/4:
* Updated the error message for NOT_BALANCED_10.
* Refined the conditional logic to avoid updating backtrack_pos
  when processing the first operand and the optional argument is
  not present.

PATCH 4/4:
* No changes, previously approved.

Hi,

The following patch series add support for POE2 extension.

This is done by adding support for feature FEAT_S1POE2 (+poe2 flag) to
support TCHANGE{F/B} instructions and all the system registers. Also
adds support for feature FEAT_TEV (+tev flag) to support TENTER/TEXIT
instructions.

Also adds the suport for PLBI instructions and corresponding system
registers.
