[PATCH] block: Turn bvec_k{un,}map_irq() into static inlinefunctions

[Geert Uytterhoeven]

Convert bvec_k{un,}map_irq() from macros to static inline functions if
!CONFIG_HIGHMEM, so we can easier detect mistakes like the one fixed in
93055c31045a2d5599ec613a0c6cdcefc481a460 ("ps3disk: passing wrong variable to
bvec_kunmap_irq()")

Compile-tested on m68k only. Not on ppc64 with the old ps3disk.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
