ARM: Initialize ptl->lock for vector page

2011-12-28T22:25:33+00:00

Without this patch, ARM can not use SPLIT_PTLOCK_CPUS if
PREEMPT_RT_FULL=y because vectors_user_mapping() creates a
VM_ALWAYSDUMP mapping of the vector page (address 0xffff0000), but no
ptl->lock has been allocated for the page.  An attempt to coredump
that page will result in a kernel NULL pointer dereference when
follow_page() attempts to lock the page.

The call tree to the NULL pointer dereference is:

   do_notify_resume()
      get_signal_to_deliver()
         do_coredump()
            elf_core_dump()
               get_dump_page()
                  __get_user_pages()
                     follow_page()
                        pte_offset_map_lock() <----- a #define
                           ...
                              rt_spin_lock()

The underlying problem is exposed by mm-shrink-the-page-frame-to-rt-size.patch.

mm: pagefault_disabled()

2011-12-28T22:25:23+00:00

Wrap the test for pagefault_disabled() into a helper, this allows us
to remove the need for current->pagefault_disabled on !-rt kernels.

mm: Fixup all fault handlers to check current->pagefault_disable

2011-12-28T22:25:23+00:00

Necessary for decoupling pagefault disable from preempt count.
