* [MIPS] Fix aliasing bug in copy_user_highpage, take 2.Ralf Baechle2007-10-161-7/+12
| | | | | | | | | | | | | | Turns out b868868ae0f7272228c95cc760338ffe35bb739d wasn't quite right. When called for a page that isn't marked dirty it would artificially create an alias instead of doing the obvious thing and access the page via KSEG0. The same issue also exists in copy_to_user_page and copy_from_user_page which was causing the machine to die under rare circumstances for example when running ps if the BUG_ON() assertion added by the earlier fix was getting triggered.

* | [MIPS] Don't abort the build process if '-msym32' isn't supportedFranck Bui-Huu2007-10-111-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | -msym32 and previously the strategy to tell the compiler to generate 64-bit code but the assembler to put it into 32-bit ELF was initially a hack to get around the lack of proper 64-bit binutils support and later turned into a neat optimization with significant code size savings. But it's really just an optimization so there is nothing wrong with just dropping the option (and whatever else goes along with it, I forgot all the nasty details) on the floor if due to a vintage compiler it can't be suported.
