Impact: cleanup

Each SMP arch defines these themselves.  Move them to a central
location.

Twists:
1) Some archs (m32, parisc, s390) set possible_map to all 1, so we add a
   CONFIG_INIT_ALL_POSSIBLE for this rather than break them.

2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'.
   Those archs simply have phys_cpu_present_map replaced everywhere.

3) Alpha defined cpu_possible_map to cpu_present_map; this is tricky
   so I just manipulate them both in sync.

4) IA64, cris and m32r have gratuitous 'extern cpumask_t cpu_possible_map'
   declarations.

Russell King did the following back in 2003:

<--  snip  -->

    [PCI] pci-9: Kill per-architecture pcibios_update_resource()

    Kill pcibios_update_resource(), replacing it with pci_update_resource().
    pci_update_resource() uses pcibios_resource_to_bus() to convert a
    resource to a device BAR - the transformation should be exactly the
    same as the transformation used for the PCI bridges.

    pci_update_resource "knows" about 64-bit BARs, but doesn't attempt to
    set the high 32-bits to anything non-zero - currently no architecture
    attempts to do something different.  If anyone cares, please fix; I'm
    going to reflect current behaviour for the time being.

    Ivan pointed out the following architectures need to examine their
    pcibios_update_resource() implementation - they should make sure that
    this new implementation does the right thing.  #warning's have been
    added where appropriate.

        ia64
        mips
        mips64

    This cset also includes a fix for the problem reported by AKPM where
    64-bit arch compilers complain about the resource mask being placed
    in a u32.

<--  snip  -->

This patch removes the unused pcibios_update_resource() functions the
kernel gained since, from FRV, m68k, mips & sh architectures.

This replaces the MIPS-specific to_tm function with the generic
rtc_time_to_tm function.  The big difference between the two functions is
that rtc_time_to_tm uses epoch 70 while to_tm uses 1970, so the result of
rtc_time_to_tm needs to be fixed up.

Serial driver patch for the PMC-Sierra MSP71xx devices.

There are three different fixes:

1 Fix for DesignWare APB THRE errata: In brief, this is a non-standard
  16550 in that the THRE interrupt will not re-assert itself simply by
  disabling and re-enabling the THRI bit in the IER, it is only re-enabled
  if a character is actually sent out.

  It appears that the "8250-uart-backup-timer.patch" in the "mm" tree
  also fixes it so we have dropped our initial workaround.  This patch now
  needs to be applied on top of that "mm" patch.

2 Fix for Busy Detect on LCR write: The DesignWare APB UART has a feature
  which causes a new Busy Detect interrupt to be generated if it's busy
  when the LCR is written.  This fix saves the value of the LCR and
  rewrites it after clearing the interrupt.

3 Workaround for interrupt/data concurrency issue: The SoC needs to
  ensure that writes that can cause interrupts to be cleared reach the UART
  before returning from the ISR.  This fix reads a non-destructive register
  on the UART so the read transaction completion ensures the previously
  queued write transaction has also completed.
