On little endian builds call H_SET_MODE so exceptions have the
correct endianness. We need to reset the endian during kexec
so do that in the MMU hashtable clear callback.

Nit picking, but I'm not sure the enable_big/little_endian_exceptions()
wrappers buy us much. And they mean you end up with essentially the same
routine twice below:

Whereas you could do:
static long pseries_big_endian_exceptions(bool big_endian)
{
int mflags;
long rc;
mflags = big_endian ? 0 : 1;
while (1) {
rc = plpar_set_mode(mflags, 4, 0, 0);
if (!H_IS_LONG_BUSY(rc))
return rc;
mdelay(get_longbusy_msecs(rc));
}
}
Perhaps pseries_big_endian_exceptions(false) looks a bit odd though ..

Little endian ppc64 is getting an exciting new ABI. This is reflected
by the bottom two bits of e_flags in the ELF header:
0 == legacy binaries (v1 ABI)
1 == binaries using the old ABI (compiled with a new toolchain)
2 == binaries using the new ABI.
We store this in a thread flag, because we need to set it in core
dumps and for signal delivery. Our chief concern is that it doesn't
use function descriptors.

Just to be ridiculously clear for stupid people like me, you refer here
to the "v1 ABI" and "the old ABI" - they are the same thing - right?

This is the first TIF flag we #ifdef for 32 vs 64, is that just because
we don't want to waste a flag on 32 bit?

No, it's because I wanted to make damn sure that there wasn't anyone
testing this in 32-bit code, since ELF2 is currently a 64-bit only
option.

No function descriptor, but we set r12 up and set TIF_RESTOREALL as it
normally isn't restored on return from syscall.

For the ELFv2 ABI, the hander is the entry point, not a function descriptor.
We also need to set up r12, and fortunately the fast_exception_return
exit path restores r12 for us so nothing else is required.

The kernel doesn't build correctly using the ELFv2 ABI. This patch
ensures that the ELFv1 ABI is used when building a kernel with an
ELFv2 enabled compiler.

This appears to do nothing, but the Makefile bits were already added in
commit d72b080 "powerpc: Add ability to build little endian kernels".
