there are no kernels currently that do page coloring, so the only use of cachectl[] is flushing the icache (on arm and ppc). on pc64, cachectl consumes 32 bytes in each page resulting in over 200 megabytes of overhead for 32gb of ram with 4K pages. this change removes cachectl[] and adds txtflush ulong that is set to ~0 by pio() to instruct putmmu() to flush the icache. |
