- * - Before invoking a signal handler, we save the unsaved

- *
- * - If the unsaved callee-save registers are modified, we set
- * a bit in pt_regs so we know to reload them from pt_regs

- * registers (including "lr"). It does not check what PL it is being

- * The <atomic.h> wrapper assumes it only clobbers r20-r29, so if
- * it ever is necessary to use more registers, be aware.
- *
- * It does not use the stack, but since it might be re-interrupted by
- * a page fault which would assume the stack was valid, it does
- * save/restore the stack pointer and zero it out to make sure it gets reset.
- * Since we always keep interrupts disabled, the hypervisor won't
- * clobber our EX_CONTEXT_K_x registers, so we don't save/restore them
- * (other than to advance the PC on return).
- *
- * We have to manually validate the user vs kernel address range
- * (since at PL1 we can read/write both), and for performance reasons
- * we don't allow cmpxchg on the fc000000 memory region, since we only
- * validate that the user address is below PAGE_OFFSET.
- *
- * We place it in the __HEAD section to ensure it is relatively

- *
- * Our use of ATOMIC_LOCK_REG here must match do_page_fault_ics().
