arm64: fix alignment padding in assembly code
An interesting effect of using the generic version of linkage.h
is that the padding is defined in terms of x86 NOPs, which can have
even more interesting effects when the assembly code looks like this:
ENTRY(func1)
mov x0, xzr
ENDPROC(func1)
// fall through
ENTRY(func2)
mov x0, #1
ret
ENDPROC(func2)
Admittedly, the code is not very nice. But having code from another
architecture doesn't look completely sane either.
The fix is to add arm64's version of linkage.h, which causes the insertion
of proper AArch64 NOPs.

results in guest memory corruption and or the hardware faulting and 'crashing'

MODSIGN: Move the magic string to the end of a module and eliminate the search
Emit the magic string that indicates a module has a signature after the
signature data instead of before it. This allows module_sig_check() to
be made simpler and faster by the elimination of the search for the
magic string. Instead we just need to do a single memcmp().
This works because at the end of the signature data there is the
fixed-length signature information block. This block then falls
immediately prior to the magic number.
From the contents of the information block, it is trivial to calculate
the size of the signature data and thus the size of the actual module
data.

pidns: remove recursion from free_pid_ns()
free_pid_ns() operates in a recursive fashion:
free_pid_ns(parent)
put_pid_ns(parent)
kref_put(&ns->kref, free_pid_ns);
free_pid_ns
thus if there was a huge nesting of namespaces the userspace may trigger
avalanche calling of free_pid_ns leading to kernel stack exhausting and a
panic eventually.
This patch turns the recursion into an iterative loop.

kbuild: Fix module signature generation
Rusty had clearly not actually tested his module signing changes that I
(trustingly) applied as commit
e2a666d52b48 ("kbuild: sign the modules
at install time"). That commit had multiple bugs:
- using "${#VARIABLE}" to get the number of characters in a shell
variable may look clever, but it's locale-dependent: it returns the
number of *characters*, not bytes. And we do need bytes.
So don't use "${#..}" expansion, do the stupid "wc -c" thing instead
(where "c" stands for "bytes", not "characters", despite the letter.
- Rusty had confused "siglen" and "signerlen", and his conversion
didn't set "signerlen" at all, and incorrectly set "siglen" to the
size of the signer, not the size of the signature.
End result: the modified sign-file script did create something that
superficially *looked* like a signature, but didn't actually work at
all, and would fail the signature check. Oops.
Tssk, tssk, Rusty.
But Rusty was definitely right that this whole thing should be rewritten
in perl by somebody who has the perl-fu to do so. That is not me,
though - I'm just doing an emergency fix for the shell script.

I'm aware that is is a little late for the UAPI renames for the DVB
API, but IMHO, it is better to merge it for 3.7, due to two reasons:
1) There is a major rename at 3.7 (not only uapi changes, but also
the entire media drivers were reorganized on 3.7, in order to
simplify the Kconfig logic, and easy drivers selection, especially
for hybrid devices). By confining all those renames there at 3.7
it will cause all the harm at for media developers on just one
shot. Stable backports upstream and at distros will likely
welcome it as well, as they won't need to check what changed on
3.7 and what was postponed for on 3.8.
2) The V4L2 DocBook Makefile creates a cross-reference between the
media API headers and the specs. This helps us _a_lot_ to be sure
that all API improvements are properly documented. Every time a
header changes from one place to another, DocBook/media/Makefile
needs to be patched. Currently, the DocBook breakage patch

If the name passed to simple_xattr_remove() does not exist in the list of
xattrs, then it is possible to call kfree(new_xattr) when new_xattr is
actually initialized to itself on the stack via uninitialized_var().
This causes a BUG() since the memory was not allocated via the slab

Initialize the local variable to NULL so the kfree() never takes place.

arm64: No need to set the x0-x2 registers in start_thread()
For historical reasons, ARM used to set r0-r2 in start_thread() to the
first values on the user stack when starting a new user application. The
same logic has been inherited in AArch64. The x0 register is overridden
by the sys_execve() return value so it's always zero on success. The x1
and x2 registers are ignored by AArch64 and EABI AArch32 applications,
so we can safely remove the register setting for both native and compat
user space.
This also fixes a potential fault with the kernel accessing user space
stack directly.

arm64: Ignore memory blocks below PHYS_OFFSET
According to Documentation/arm64/booting.txt, the kernel image must be
loaded at a pre-defined offset from the start of RAM so that the kernel
can calculate PHYS_OFFSET based on this address. If the DT contains
memory blocks below this PHYS_OFFSET, report them and ignore the
corresponding memory range.
