2019-12-02src/: Remove g_ prefixes and _g suffixes from variablesPatrick Georgi
These were often used to distinguish CAR_GLOBAL variables that weren't directly usable. Since we're getting rid of this special case, also get rid of the marker. This change was created using coccinelle and the following script: @match@ type T; identifier old =~ "^(g_.*|.*_g)$"; @@ old @script:python global_marker@ old << match.old; new; @@ new = old if old[0:2] == "g_": new = new[2:] if new[-2:] == "_g": new = new[:-2] coccinelle.new = new @@ identifier match.old, global_marker.new; @@ - old + new @@ type T; identifier match.old, global_marker.new; @@ - T old; + T new; @@ type T; identifier match.old, global_marker.new; @@ - T old + T new = ...; There were some manual fixups: Some code still uses the global/local variable naming scheme, so keep g_* there, and some variable names weren't completely rewritten.

Newer CPUs/SoCs need to configure other features via the IA32_FEATURE_CONTROL msr, such as SGX, which cannot be done if the msr is already locked. Create separate functions for setting the vmx flag and lock bit, and rename existing function to indicate that the lock bit will be set in addition to vmx flag (per Kconfig). This will allow Skylake/Kabylake (and others?) to use the common VMX code without breaking SGX, while ensuring no change in functionality to existing platforms which current set both together.
