+ Align kernel to 2MiB boundary in u-boot + Optimize alignment functions a little bit, should still have to check on real hardware but 'feels' more clean + Add early boot debugging + Put extra cores we aren't ready to account for to sleep if/when they boot. + Make BASE_PAGE_SIZE constant on riscv64/32, helps the compiler with some alignment checks among other things.

+ No real point having multiple different levels of assertions, just say you assert something and be done with it
2024-07-07smp now seems to workKimplul
+ Had some minor issues with a wraparound of size_t that effectively meant that some regions were allocated twice. Also, booting should be a bit more reliable now, turned out that the previous iteration of the booting was just accidentally working due to the kernel being placed 'close enough' in RAM to where it was linked to. Fixed by allocating a vmem of O1 that maps the kernel to a 2MiB boundary at boot, pretty nifty.
2024-07-06pretty massive virtual memory rewriteKimplul
+ The system is now a bit simpler and hopefully easier to understand, while also extending the shared memory to be 1:N, where there is one owner who may become a zombie while waiting for the N to die.
