As the Processor Version Register (PVR) is a 32-bit PowerPC
register, change mfpvr() return type to match it and avoid
type casts on its callers.

Suggested by: jhibbits

Test Plan

Tested on POWER9 VM and build tested on powerpc (32-bit).

minor quibble, but likely not worth addressing.


mfpvr() doesn't return an int now, but a uint32_t which can be either an int or a long. so there's still a mismatch here, just not one the compiler warns about. In the past, this would be a sure way to get a mismatch between 32-bit and 64-bit compiles, but it seems we've moved to always defining uint32_t as an unsigned int. At least the 'x' format is unsigned...
