linux-toradex.git/arch/powerpc/kernel/ppc_ksyms.c, branch v3.14.15

Merge branch 'for-kvm' into next

2013-10-11T07:23:53+00:00

Topic branch for commits that the KVM tree might want to pull
in separately.

Hand merged a few files due to conflicts with the LE stuff

powerpc: Provide for giveup_fpu/altivec to save state in alternate location

2013-10-11T06:26:50+00:00

This provides a facility which is intended for use by KVM, where the
contents of the FP/VSX and VMX (Altivec) registers can be saved away
to somewhere other than the thread_struct when kernel code wants to
use floating point or VMX instructions.  This is done by providing a
pointer in the thread_struct to indicate where the state should be
saved to.  The giveup_fpu() and giveup_altivec() functions test these
pointers and save state to the indicated location if they are non-NULL.
Note that the MSR_FP/VEC bits in task->thread.regs->msr are still used
to indicate whether the CPU register state is live, even when an
alternate save location is being used.

This also provides load_fp_state() and load_vr_state() functions, which
load up FP/VSX and VMX state from memory into the CPU registers, and
corresponding store_fp_state() and store_vr_state() functions, which
store FP/VSX and VMX state into memory from the CPU registers.

powerpc: Added __cmpdi2 for signed 64bit comparision

2013-10-11T05:49:27+00:00

This was missing on powerpc and I am getting compilation error
drivers/vfio/pci/vfio_pci_rdwr.c:193: undefined reference to `__cmpdi2'

powerpc: Use generic memcpy code in little endian

2013-10-11T05:48:40+00:00

We need to fix some endian issues in our memcpy code. For now
just enable the generic memcpy routine for little endian builds.

powerpc: Remove the empty giveup_fpu() function on 32bit kernel

2013-08-14T04:59:50+00:00

Instead of implementing an empty giveup_fpu() function for each
32bit processor type, replace them with an unique empty inline
function.

powerpc: Remove the symbol __flush_icache_range

2013-08-14T04:56:44+00:00

And now the function flush_icache_range() is just a wrapper which
only invoke the function __flush_icache_range() directly. So we
don't have reason to keep it anymore.

powerpc: Provide __bswapdi2

2013-05-14T06:00:17+00:00

Some versions of GCC apparently expect this to be provided by libgcc.

Updates from Mikey to fix 32 bit version and adding "r" to registers.
