From: Ralf Baechle Date: Thu, 8 Nov 2012 22:59:31 +0000 (+0100) Subject: MIPS: compat: Implement is_compat_task() by testing for 32-bit address space. X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6ad560b4546af6943820f780610e544aaae218c0;p=linux-beck.git MIPS: compat: Implement is_compat_task() by testing for 32-bit address space. So far is_compat_task() was testing for 32-bit registers if O32 support was enabled and if O32 support was disabled but N32 enabled it was testing for 32-bit address space. So if both O32 and N32 were enabled a N32 task was not considered a compat task, whops. This still leaves potential cases where O32 and N32 need different treatment unsolved. But that's another commit.
