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".
