Subject: smp: print active CPU count for single-CPU boot
X-Git-Url: https://projects.tadryanom.me/?a=commitdiff_plain;h=eead6c0bda5414940b6c0e7c09538467689af1fb;p=AdrOS.git

smp: print active CPU count for single-CPU boot

smp_start_aps() returned early without printing the 'CPU(s) active.'
message when g_cpu_count <= 1, causing the battery test SMP1 boot
pattern to fail. Now prints '[SMP] 1 CPU(s) active.' in that case.

Battery test: 148/148 PASS (was 147/148 with SMP1 boot FAIL)
