* Page table entry handling code was changed. Bit 56 is now used as an is valid/present flag. Previously checks that checked entries with bitmask 0x3 now check 0x100000000000002.

* KPageTableBase now has an additional data member storing how much unsafe memory is currently mapped. (This value is incremented/decremented on calls to svcMapPhysicalMemoryUnsafe/svcUnmapPhysicalMemoryUnsafe).

* KPageTableBase::LockForIpc* now takes a KPhysicalAddress * argument. Mapping code will try to write the physical address of the locked virtual address to this out pointer, KernelPanic() is called if physical address translation fails.
* KServerSession::SendReply now takes an additional argument for the physical address of the user message buffer. NULL is passed when doing ReplyAndReceive without a user buffer.
** When this argument is not null, the message buffer is accessed by doing linear phys-to-virt translation on this physaddress, otherwise the message buffer is accessed by doing linear phys-to-virt translation on the TLS physical address.
** Previously, the process virtual address for the user buffer was accessed directly.
