Hi all,
Today's linux-next merge of the tip tree got a conflict in
arch/mips/Kconfig between commit 597ce1723e0f ("MIPS: Support for 64-bit
FP with O32 binaries") from the mips tree and commit 19952a92037e
("stackprotector: Unify the HAVE_CC_STACKPROTECTOR logic between
architectures") from the tip tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).

- config CC_STACKPROTECTOR
- bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
- help
- This option turns on the -fstack-protector GCC feature. This
- feature puts, at the beginning of functions, a canary value on
- the stack just before the return address, and validates
- the value just before actually returning. Stack based buffer
- overflows (that need to overwrite this return address) now also
- overwrite the canary, which gets detected and the attack is then
- neutralized via a kernel panic.
-
- This feature requires gcc version 4.2 or above.

+config MIPS_O32_FP64_SUPPORT
+ bool "Support for O32 binaries using 64-bit FP"
+ depends on 32BIT || MIPS32_O32
+ default y
+ help
+ When this is enabled, the kernel will support use of 64-bit floating
+ point registers with binaries using the O32 ABI along with the
+ EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
+ 32-bit MIPS systems this support is at the cost of increasing the
+ size and complexity of the compiled FPU emulator. Thus if you are
+ running a MIPS32 system and know that none of your userland binaries
+ will require 64-bit floating point, you may wish to reduce the size
+ of your kernel & potentially improve FP emulation performance by
+ saying N here.

+ If unsure, say Y.
