    SubjectINVLPG Instruction
    From
    Hello

    When a process has a page fault and Linux swaps out a page ( no more
    free page ) from another process and give it to the page-faulting
    process. Typically a INVLPG is used to invalidate entries in the TLB.
    I would like to know whether INVLPG is global ( i.e. across all cores
    )? How does the process which Linux stole the page from get informed (
    how is its tlb invalidated) ?

    Thanks
