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
