86a119ea51 scheduler: Fix page table switch for scheduler 
The userspace process may map pages where the kernel has allocated data and cause a crash.

This patch fixes this issue by having a separate IRQ handler which sets the kernel page table at the start of SchedulerInterruptHandler() and restores it in SchedulerHandlerStub() function.
