Use new return type vm_fault_t for fault handler. For
now, this is just documenting that the function returns
a VM_FAULT value rather than an errno. Once all instances
are converted, vm_fault_t will become a distinct type.

Currently the code is split over various files with dma- prefixes in the
lib/ and drives/base directories, and the number of files keeps growing.
Move them into a single directory to keep the code together and remove
the file name prefixes. To match the irq infrastructure this directory
is placed
Hi all,
I'm tempted to send this little file move series to Linus around -rc1
where it would cause the least harm.
Opinions?

We already have exact config symbols to select the direct, non-coherent,
or virt dma ops. So use the normal obj- scheme to select them.

Bump up the maximum numbers of micro-TLBS to 48.
Each IPMMU device instance get micro-TLB assignment via
the "iommus" property in DT. Older SoCs tend to use a
maximum number of 32 micro-TLBs per IPMMU instance however
newer SoCs such as r8a7796 make use of up to 48 micro-TLBs.
