Hmm... it would be nice to match the style of the statement after
this, something like:
if (is_leon) {
flush_tlb_mm(0);
if (leon_flush_during_switch)
leon_flush_cache_all();
}
But that would mean that the leon_flush_during_switch and
leon_flush_cache_all() would have to be defined for the non-SPARC_LEON
case, which isn't what you're trying to do here, however if
leon_flush_cache_all() is defined as a blank function, the compiler
*should* optimise all this away.
I'm not shure what to do here. I wonder weather
if (is_leon) {
is better than a
#ifdef CONFIG_SPARC_LEON
it seems to me that the later is better.
It seems to me that in case of the former you have to have the
implicit knowledge that the compiler will optimize away the
function calls (and you have to search your way through the source
code to come to a conclusion that it will), and this is quite more
complex and disturbing than a #ifdef. I'd think #ifdef CONFIG_SPARC_LEON
is much cleaner.
Moreover it is not in line with the general strategy: to make leon-specific
parts be only compiled in when CONFIG_SPARC_LEON is defined. Then all leon_mm.c
and leon_kernel.c should also be compiled in always and protected with is_leon()
instead of only compiling it in the CONFIG_SPARC_LEON case...
But, hey, he, who checkes in, decides. Maybe Dave Miller can say how it should be.
