This fixes various small issues that pop up on Apple M1:
sysctl -n machdep.cpu.brand_string
" inget_cpu_vendor
to determine CPU type, since "sysctl -n machdep.cpu.vendor
" is not supported on Apple M1 systems;Apple
as known CPU vendor;get_cpu_speed
crashes when it fails to determine CPU speed via "sysctl -n hw.cpufrequency_max
" (which returns empty string on Apple M1), and just returnNone
;get_cpu_features
because "sysctl -n machdep.cpu.extfeatures
" is not supported on Apple M1 (and leave list of CPU features empty, for now);systemtools
tests so they pass on Apple M1;Also requires #4014 for all
