Subject: [git pull] Please pull powerpc.git merge branch
Hi Linus !
With my previous pull request I mentioned some remaining Little Endian
patches, notably support for our new ABI, which I was sitting on making
sure it was all finalized.
The toolchain folks confirmed it now, the new ABI is stable and merged
with gcc, so we are all good. Oh and we actually missed the actual
Kconfig switch for LE so here it is, along with a couple more bug fixes.
I have more fixes but not related to LE so I'll send them as a separate
pull request tomorrow, let's get this one out of the way.
Note that this supports running user space binaries using the new ABI,
but the kernel itself still needs to be built with the old one. We'll
bring fixes for that after -rc1.
Here's Anton log that goes with this series:
<<<
This patch series adds support for the new ABI, LPAR support
for H_SET_MODE and finally adds a kconfig option and defconfig.
ABIv2 support was recently committed to binutils and gcc, and
should be merged into glibc soon. There are a number of
very nice improvements including the removal of function
descriptors. Rusty's kernel patches allow binaries of either
ABI to work, easing the transition.
>>>
Cheers,
Ben.
