These patches convert several architectures to use page table folding and

IMC(In-memory Collection Counters) does performance monitoring in
two different modes, i.e accumulation mode(core-imc and thread-imc events),
and trace mode(trace-imc events). A cpu thread can either be in
accumulation-mode or trace-mode at a time and this is done via the LDBAR
register in POWER
commit <249fad734a25> ""powerpc/perf: Disable trace_imc pmu"
disables IMC(In-Memory Collection) trace-mode in kernel, since frequent
mode switching between accumulation mode and trace mode via the spr LDBAR
in the hardware can trigger a checkstop(system crash).

These calls can be used by Linux to annotate BUG addresses with symbols,
look up symbol addresses in xmon, etc.
This is preferable over having Linux parse the OPAL symbol map itself,
because OPAL's parsing code already exists for its own symbol printing,
and it can support other code regions than
Provide CONFIG_ARCH_HAS_ADDRESS_LOOKUP which allows architectures to
do their own symbol/address lookup if kernel and module lookups miss.
powerpc will use this to deal with firmware symbols.
