* The raw_reg_{read,write} macros are intended as a micro-optimization for
* interrupt handlers so that the pointer indirection on uncore->regs can
* be computed once (and presumably cached in a register) instead of generating
* extra load instructions for each MMIO access.
*
* Given that these macros are only intended for non-GSI interrupt registers
* (and the goal is to avoid extra instructions generated by the compiler),
* these macros do not account for uncore->gsi_offset. Any caller that needs
* to use these macros on a GSI register is responsible for adding the
* appropriate GSI offset to the 'base' parameter.
