DiskCache now consists of PageCaches which are caches of contiguous
sectors. This allows the disk cache to be ordered and faster traversal.
We seem to have a problem somewhere during reading. The stack gets

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

I removed the intermediate function when calling syscalls. Now syscall
handler calls the current process automatically. Only exception is
sys_fork, since it needs a assembly trampoline for the new thread.
