28362d5153 ARM: mach-omap1: clean up debug-macro.S 
This achieves two goals:

1) Get rid of omap_uart_v2p() and omap_uart_p2v() which were the last users
   of PLAT_PHYS_OFFSET.

2) Remove the probing of the M bit in the CP15 control reg and make
   the access to the .data variables completely position independent.

639da5ee37 ARM: add an extra temp register to the low level debugging addruart macro 
Some platforms (like OMAP not to name it) are doing rather complicated
hacks just to determine the base UART address to use.  Let's give their
addruart macro some slack by providing an extra work register which will
allow for much needed cleanups.

This is basically a no-op as this commit is only adding the extra argument
to the macro but no one is using it yet.

98b0124f0e ARM: mach-prima2: move ARM_DMA_ZONE_SIZE to mdesc->dma_zone_size 
Original comment:

  Restrict DMA-able region to workaround silicon limitation.
  The limitation restricts buffers available for DMA to SD/MMC
  hardware to be below 256MB.

    xen: PV on HVM: support PV spinlocks and IPIs

This change replaced the SMP operations with event based handlers without
taking into account that this only works when the hypervisor supports
callback vectors. This causes unexplainable hangs early on boot for
HVM guests with more than one CPU.

389d12cc7f ARM: mxc: Remove setting of consistent dma size 
All in-tree MX boards using video use memblock_* functions to get their
coherent dma space for the camera. So there is no need to increase
CONSISTENT_DMA_SIZE beyond the default 2MB and we can simply remove the
defines which do this.
