[edk2] [PATCH v3 0/2] UefiCpuPkg: [CVE-2017-5715] Stuff RSB before RSM

Posted by Hao Wu 16 weeks ago
V3 changes:
A. Add relating CVE issue number to the commits' subject line.

B. Keep the URL links within log messages unwrapped.

C. Add TianoCore Bugzilla link reference to each commits.

D. Mention further actions should be taken after pushing the series in log
   messages.

E. Refine file description comments for StuffRsb.inc files.

V2 changes:
A. Refine commit log message to clarify the purpose of the series

B. Extract the RSB stuffing logic to INC files to avoid code duplication:
When compiling .NASM source files, the current build rule does not support
including files other than the .NASM file directory, this series will
duplicate the StuffRsb.inc file together with the .NASM files at this
moment.

Please consider this approach as the first stage, I have filed a Bugzilla
for adding $(INC)-like support when compiling .NASM files:
https://bugzilla.tianocore.org/show_bug.cgi?id=1085

After the above support is added, the next step will be taken to remove
those duplicated StuffRsb.inc files and put it under a common include
directory like:
UefiCpuPkg/Include/
