Rework of SMTC support to make it work with the new clock event system,
allowing "tickless" operation, and to make it compatible with the use of
the "wait_irqoff" idle loop. The new clocking scheme means that the
previously optional IPI instant replay mechanism is now required, and has
been made more robust.Signed-off-by: Kevin D. Kissell

Though from a hardware perspective it would be sensible to use only a
32-bit unsigned int type Linux defines interrupt flags to be stored in
an unsigned long and nothing else.Signed-off-by: Ralf Baechle

When we use > 4KB's page size the original definition is not consistent
with PGDIR_SIZE. For exeample, if we use 16KB page size the PGDIR_SHIFT is
(14-2) + 14 = 26, PGDIR_SIZE is 2^26，so the PTRS_PER_PGD should be:2^32/2^26 = 2^6
but the original definition of PTRS_PER_PGD is 4096 (PGDIR_ORDER = 0).
So, this definition needs to be consistent with the PGDIR_SIZE.
And the new definition is consistent with the PGD init in pagetable_init().

trap_init issues flush_icache_range(), which uses ipi functions to
get icache flushing done on all cpus. But this is done before interrupts
are enabled and caused WARN_ON messages. This changeset introduces
a new local_flush_icache_range() and uses it before interrupts (and
additional CPUs) are enabled to avoid this problem.Signed-off-by: Thomas Bogendoerfer

Rename KEXEC_CONTROL_CODE_SIZE to KEXEC_CONTROL_PAGE_SIZE, because control
page is used for not only code on some platform. For example in kexec
jump, it is used for data and stack too.[akpm@linux-foundation.org: unbreak powerpc and arm, finish conversion]

The new kgdb architecture specific handler registers and unregisters
dynamically for exceptions depending on when you configure a kgdb I/O
driver.Aside from initializing the exceptions earlier in the boot process,
kgdb should have no impact on a device when it is compiled in so long
as an I/O module is not configured for use.There have been quite a number of contributors during the existence of
this patch (see arch/mips/kernel/kgdb.c). Most recently Jason
re-wrote the mips kgdb logic to use the die notification handlers.Signed-off-by: Jason Wessel
