Description Adina Roffelsen 2020-02-04 10:44:19 MST 
Kernel currently requires the boot to initialize the CS register but the requirements are imprecise about the value to set it to. By initializing the CS register, the kernel will be more consistent with its initialization of all other segment registers and be able to change the required value independent of boot. Note: boot still needs to initialize the CS register to a valid value, but the value will be overwritten by the kernel.
Comment 1 Adina Roffelsen 2020-02-04 11:23:10 MST 
Committed SVNRevision 64325.

For X86, Initialize CS register at Startup. Add to release notes.
Comment 2 Adina Roffelsen 2020-02-04 11:44:53 MST 
Committed SVNRevision 64328.

Update version string to indicate an enhancement instead of a bug fix.
Comment 3 Adina Roffelsen 2020-02-04 14:14:09 MST 
Changes are sufficient for kernel release 10.1.0. Tracing, requirements, and test still need to be completed before PCR is complete.
