1187 6626 d 5 h jermar /kernel/trunk/ Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.

ppc32: get framebuffer parameters from boot loader		  
1132 6646 d 3 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
1124 6646 d 12 h jermar /kernel/trunk/arch/ Small changes.
