x86/acpi, x86/boot: Take RSDP address for boot params if available
In case the RSDP address in struct boot_params is specified don't try
to find the table by searching, but take the address directly as set
by the boot loader.

x86/boot: Add ACPI RSDP address to setup_header
Xen PVH guests receive the address of the RSDP table from Xen. In order
to support booting a Xen PVH guest via Grub2 using the standard x86
boot entry we need a way for Grub2 to pass the RSDP address to the
kernel.
For this purpose expand the struct setup_header to hold the physical
address of the RSDP address. Being zero means it isn't specified and
has to be located the legacy way (searching through low memory or
EBDA).
While documenting the new setup_header layout and protocol version
2.14 add the missing documentation of protocol version 2.13.
There are Grub2 versions in several distros with a downstream patch
violating the boot protocol by writing past the end of setup_header.
This requires another update of the boot protocol to enable the kernel
to distinguish between a specified RSDP address and one filled with
garbage by such a broken Grub2.
From protocol 2.14 on Grub2 will write the version it is supporting
(but never a higher value than found to be supported by the kernel)
ored with 0x8000 to the version field of setup_header. This enables
the kernel to know up to which field Grub2 has written information
to. All fields after that are supposed to be clobbered.

x86: Make x32 syscall support conditional on a kernel parameter
Enabling x32 in the standard amd64 kernel would increase its attack
surface while provide no benefit to the vast majority of its users.
No-one seems interested in regularly checking for vulnerabilities
specific to x32 (at least no-one with a white hat).
Still, adding another flavour just to turn on x32 seems wasteful. And
the only differences on syscall entry are a few instructions that mask
out the x32 flag and compare the syscall number.
Use a static key to control whether x32 syscalls are really enabled, a
Kconfig parameter to set its default value and a kernel parameter
"syscall.x32" to change it at boot time.

We want the 686 flavour to run on Geode LX and similar AMD family 5

currently enables CONFIG_X86_USE_3D_NOW which will cause the kernel to

mmap: Add an exception to the stack gap for Hotspot JVM compatibility
The Hotspot JVM can easily exhaust the default stack, and has a
SIGSEGV handler to cope with this by switching to a new stack segment.
However, on i386 it creates a single writable and executable page just
under the stack limit as a workaround for a bug in Exec Shield. That
together with the enlarged stack gap causes the SIGSEGV handler to be
triggered when the stack pointer is further away from the stack limit,
and it doesn't recognise this as being a stack overflow.
This specifically affects programs that use JNI. Hotspot doesn't
normally run Java code on the initial thread.
Reduce the effective stack guard gap on x86 if the previous vma is
a single page allocated as MAP_FIXED.

radeon attempts to gracefully fall back and disable some features if

Hardcode arch script output
Here's a patch that simply uses hardcoded definitions instead of
doing the dynamic tests that require architecture-specific scripts.
I don't particularly like this approach because it restricts
portability and diverts from upstream. But, it is simpler, and this
really needs to be fixed somehow before etch (along with a rebuild of
linux-modules-extra-2.6), so I'm willing to live with it if my other
patch is deemed unacceptable.
My primary concern is that, in the future, the output of these scripts
will change and we (or our successors) will either not notice or
forget to update the hardcoded values.
Including the scripts in linux-kbuild will avoid this manual step
altogether, and allow for the possibility of other archs to provide
