Subject[PATCH 2/2] mips: mm: Discard ioremap_uncached_accelerated() method
Date
Adaptive ioremap_wc() method is now available (see "mips: mm:
Create UCA-based ioremap_wc() method" commit). We can use it for
UCA-featured MMIO transactions in the kernel, so we don't need
it platform clone ioremap_uncached_accelerated() being declard.
Seeing it is also unused anywhere in the kernel code, lets remove
it from io.h arch-specific header then.
