Question on __pv_stub

[subin gangadharan]

Hi All,

I am just trying to understand __va macro. I can see two definitions,one
in include/asm-generic/page.h and other is in arch/arm/include/asm/memory.h.
The first definition is just adding PAGE_OFFSET,but the second one boil
downs to  __pv_stub.Could anybody please help me to understand what this
__pv_stub for?


With Regards
Subin Gangadharan

Everything should be made as simple as possible,but not simpler.
