Subject: [PATCH]: MIPS: Select CONFIG_MIPS_O32_FP64_SUPPORT if 64bit kernel and o32
Date: Wed, 01 Apr 2015 02:49:55 -0400 [thread overview]
Message-ID: <551B9513.5020606@gentoo.org> (raw)
From: Joshua Kinard <kumba@gentoo.org>
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".

Select this option if you want to run o32 binaries. These are pure
32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
