: MIPS: Select CONFIG_MIPS_O32_FP64_SUPPORT if 64bit kernel and o32
PATCH 1/1 : MIPS: Select CONFIG_MIPS_O32_FP64_SUPPORT if 64bit kernel and o32
From: Joshua Kinard <[email protected]>
Select CONFIG_MIPS_O32_FP64_SUPPORT by default if CONFIG_64BIT and CONFIG_MIPS32_O32 are selected. This avoids breaking things when booting into an o32 userland under a 64bit kernel. Symptoms of not selecting CONFIG_MIPS_O32_FP64_SUPPORT can include OpenSSH claiming that the "PRNG is not seeded" and Python programs to fail with either a SIGSEGV or errors regarding "float NaN".

Hi,
No this is not a good solution. This has already been fixed in mips-for-linux-next and might make it to 4.0 in time
https://patchwork.linux-mips.org/patch/9344/
can you try that patch instead?

This appears to fix the problem. I definitely suggest this get into 4.0, or some machines out there are going to break if CONFIG_MIPS_O32_FP64_SUPPORT isn't selected. This one was stumping me for a few hours last night...
Thanks!,
