Bananymous 10544db52e LibELF: We use BAN::Vector<uint8_t> as elf storage 
This is made possible by the dynamic kmalloc
 2023-06-18 23:29:23 +03:00
Bananymous 5e123031aa Kernel: kmalloc has now somewhat dynamic storage 
Allocations bigger than PAGE_SIZE and those not forced to be identity
mapped are now done on a GeneralAllocator. This allows us to use kmalloc
for big allocations; bigger than the fixed 1 MiB storage.

This is still a hack and the whole kmalloc will have to be rewritten at
some point, but for now this does the job :D
