x86_64/MMU: Map the kernel page directory to virtual memory
This avoids depending on the kernel address space to create a new userspace one,
since there is no physical memory access.

This was fine for a single process, since its address space was created from the kernel one
and no more address spaces were created,
but for two or more, this started to become problematic, since we would create one address space
while being in another process's address space, which has no direct mapping of physical memory.

Bitmap: Add a fallible variant of match_region() that does not crash if arguments are out of range
This lets us call deallocate_memory() with any address and it will not crash.

arch/Timer: Make sure ARCH_TIMER_FREQ is a power of two
(avoid division and modulo, division is slow)
Fortunately, GCC will optimize divisions by powers of two to simple bitwise shifts :)

luna: Make Utf8StringEncoder short-circuit instead of failing when hitting the length limit 2023-01-14 12:07:08 +01:00

luna: Make Utf8String{De,En}coders return the number of bytes written
This means we can avoid a call to code_points() in mbstowcs(),
which would parse a string twice.

Add a VERY BASIC and hacky way of allocating memory from userspace
Only supports one-page allocations and doesn't have libc wrappers, which means it has to be invoked using syscall().
