2025-05-14	kernel: get rid of Proc.kstack	glenda
	The kernel stack is now above the Proc structure, so the explicit kstack pointer can be eliminated.
2020-12-20	kernel: handle tos and per process pcycle counters in port/	cinap_lenrek
	we might as well handle the per process cycle counter in the portable part instead of duplicating the code in every arch and have inconsistent implementations. we now have a portable kenter() and kexit() function, that is ment to be used in trap/syscall from user, which updates the counters. some kernels missed initializing Mach.cyclefreq.

2019-04-11	kernel: get rid of PTR2UINT() and UINT2PTR() macros	cinap_lenrek

2018-11-04	bcm: fix mysterious core clock resets under SMP (thanks richard miller)	cinap_lenrek

But empirically it correlates with weird problems, eg * resetting of the core clock at 0x4000001C which confuses local timers. */ if(conf.nmach > 1) mmuswitch(nil); }
