X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f7a849153be3b66326b52dce0d07896b56cb4cd7;p=linux-beck.git [MIPS] Fix FIXADDR_TOP for TX39/TX49. FIXADDR_TOP is used for HIGHMEM and for upper limit of vmalloc area on 32bit kernel. TX39XX and TX49XX have "reserved" segment in CKSEG3 area. 0xff000000-0xff3fffff on TX49XX and 0xff000000-0xfffeffff on TX39XX are reserved (unmapped, uncached) therefore can not be used as mapped area.
