Ensure the kernel correctly switches VSX registers correctly. VSX
registers are all volatile, and despite the kernel preserving VSX
across syscalls, it doesn't have to. Test that during interrupts and

Hi All,
I was able to patch the RC1 with the Nemo and PHB-numbering patch.
Additionally I added some printks in the file pata_of_platform.c. I
wanted to know which values have the following variables:
ctl_res = io_res;
io_res.start += 0x800;
ctl_res.start = ctl_res.start + 0x80e;
io_res.end =
On ARM, relative branches between functions can not span more than 32MB,
which limits the size of an ELF section. In the final link, the linker
will introduce trampolines that perform long calls to avoid the limit,
and during a recursive link, trampolines are added within the section.
However, thi

hmi.c functions are unused unless sibling_subcore_state is nonzero, and
that in turn happens only if KVM is in use. So move the code to
arch/powerpc/kvm/, putting it under CONFIG_KVM_BOOK3S_HV_POSSIBLE
rather than CONFIG_PPC_BOOK3S_64. The sibling_subcore_state is also
included in struct paca_str

With the commit 44a7185c2ae6 ("of/platform: Add common method to
populate default bus"), a default function is introduced to populate
the default bus and this function is invoked at the arch_initcall_sync
level. This will override the arch specific population of default bus
which run at a lower lev
