SMP/MMU updating page tables on realview BSP

Hi,

I am working on a use case for cortex-a9/realview BSP that deals with page
tables and MMU. I need your help in gathering the required API and calls
and any other details to implement the following case (if applicable) :

1- A thread running on a core that updates the page table.
2- On another core another thread is running and trying to update the page
table.

Is that use case possible, or disabling dispatches, MMU, and interrupts
avoids that situation ?

Is it possible to force a thread to run on a specific core ? or the current
SMP scheduler handles that ?

I am thinking of applying a SHARED_MEMORY attribute on page tables itself
and implement the mentioned use case.

Regards,
Hesham
