Some CPUs have a DABR but not DABRX. Configuration are:
- No 32bit CPUs have DABRX but some have DABR.
- POWER4+ and below have the DABR but no DABRX.
- 970 and POWER5 and above have DABR and DABRX.
- POWER8 has DAWR, hence no DABRX.
This introduces CPU_FTR_DABRX and sets it on appropriate CPUs.

These comments already don't apply to the current code. So just remove
them.

The codes which ever used these two variables have gone. Throw away
them too.

For Freescale powerpc platform, the PCI-e bus number uses the reassign mode
by default. It means the second PCI-e controller's hose-first_busno is the
first controller's last bus number adding 1. For some hotpluged device(or
controlled by FPGA), the device is linked to PCI-e slot at linux runtime.

We find all the overlapping vma and mark them such that we don't allocate
hugepage in that range. Also we split existing huge page so that the
normal page hash can be invalidated and new page faulted in with new
protection bits.

We need to use smb_rmb when looking at hpte slot array. Otherwise we could
reorder the hpte_slot array load bfore even we marked the pmd trans huge.

This patch removes the Kconfig symbol HAVE_CAN_FLEXCAN from arch/{arm,powerpc}
and allowing compilation unconditionally on all arm and powerpc platforms.
This brings a bigger compile time coverage and removes the following dependency
