30415f6a63 powerpc: Fix random memory corruption in merged elf.h
The merged verison of ELF_CORE_COPY_REGS is basically the PPC64 version, with
a memset that came from PPC and a few types abstracted out into #defines. But
it's not _quite_ right.

The first problem is we calculate the number of registers with:
        nregs = sizeof(struct pt_regs) / sizeof(ELF_GREG_TYPE)

For a 32-bit process on a 64-bit kernel that's bogus because the registers are
64 bits, but ELF_GREG_TYPE is u32, so nregs == 88 which is wrong.

The other problem is the memset, which assumes a struct pt_regs is smaller
than a struct elf_regs. For a 32-bit process on a 64-bit kernel that's false.

The fix is to calculate the number of regs using sizeof(unsigned long), which
should always be right, and just memset the whole damn thing _before_ copying
the registers in.

There's no reason for smp_release_cpus() to be asm, and most people can make

40765d2b8b powerpc: Cleanup vpa code
register_vpa() doesn't actually do a VPA register call it just uses the flags
you pass it, so rename it to vpa_call() to be clearer.

We can then define register_vpa() and unregister_vpa() which are both simple
wrappers around vpa_call(). (we'll need unregister_vpa() for kexec soon)

We can then cleanup vpa_init(), and because vpa_init() is only called from
platforms/pseries we remove the definition in asm-ppc64/smp.h.

Revert to using two unsigned long longs (which is what ppc32 had
originally).  ppc64 orignally had two unsigned longs, but long long is
the same size on 64 bit, so this should be ok there too.

e19e4ab415 powerpc: Set entry point and text address in linker script
Currently we set the kernel entry point and the address of the text
section in the Makefile, using CONFIG_KERNEL_START.

But we've already got <asm/page.h> in the linker script, so we can just
use KERNELBASE directly. That means if we ever change KERNELBASE there's
one less place to change it.

And we can set the entry point with ENTRY().

There are zero differences from "readelf -a vmlinux" with or without this
patch.
