We can call vmalloc_init() after kmem_cache_init() and use kzalloc() instead of
the bootmem allocator when initializing vmalloc data structures.

This patch makes kmalloc() available earlier in the boot sequence so we can get
rid of some bootmem allocations. The bulk of the changes are due to
kmem_cache_init() being called with interrupts disabled which requires some
changes to allocator boostrap code.
Note: 32-bit x86 does WP protect test in mem_init() so we must setup traps
before we call mem_init() during boot as reported by Ingo Molnar:
We have a hard crash in the WP-protect code:

With the removal of duplicate unpack_to_rootfs() (commit
df52092f3c) the messages displayed do not
actually correspond to what the kernel is doing. In addition, depending
if ramdisks are supported or not, the messages are not at all the same.
So keep the messages more in sync with what is really doing the kernel,
and only display a second message in case of failure. This also ensure
that the printk message cannot be split by other printk's.

V3 of the early platform driver implementation.
Platform drivers are great for embedded platforms because we can separate
driver configuration from the actual driver. So base addresses,
interrupts and other configuration can be kept with the processor or board
code, and the platform driver can be reused by many different platforms.
For early devices we have nothing today. For instance, to configure early
timers and early serial ports we cannot use platform devices. This
because the setup order during boot. Timers are needed before the
platform driver core code is available. The same goes for early printk
support. Early in this case means before initcalls.
These early drivers today have their configuration either hard coded or
they receive it using some special configuration method. This is working
quite well, but if we want to support both regular kernel modules and
early devices then we need to have two ways of configuring the same
driver. A single way would be better.
The early platform driver patch is basically a set of functions that allow
drivers to register themselves and architecture code to locate them and
probe. Registration happens through early_param(). The time for the
probe is decided by the architecture code.
See Documentation/driver-model/platform.txt for more details.

Change cb6ff20807 ("NOMMU: Support XIP on
initramfs") seems to have broken booting from initramfs with /sbin/init
being a hardlink.
It seems like the logic required for XIP on nommu, i.e. ftruncate to
reported cpio header file size (body_len) is broken for hardlinks, which
have a reported size of 0, and the truncate thus nukes the contents of the
file (in my case busybox), making boot impossible and ending with runaway
loop modprobe binfmt-0000 - and of course 0000 is not a valid binary
format.
My fix is to only call ftruncate if size is non-zero which fixes things
for me, but I'm not certain whether this will break XIP for those files on
nommu systems, although I would guess not.

Make it possible for the linker to discard local symbols from vmlinux as

With this we add a config option (CONFIG_STRIP_ASM_SYMS) that will cause

Create a dynamically sized pool of threads for doing very slow work items, such
as invoking mkdir() or rmdir() - things that may take a long time and may
sleep, holding mutexes/semaphores and hogging a thread, and are thus unsuitable
for workqueues.
The number of threads is always at least a settable minimum, but more are
started when there's more work to do, up to a limit. Because of the nature of
the load, it's not suitable for a 1-thread-per-CPU type pool. A system with
one CPU may well want several threads.
This is used by FS-Cache to do slow caching operations in the background, such
as looking up, creating or deleting cache objects.

(Thanks to Al Viro for reminding me of this, via Ingo)
CPU_MASK_ALL is the (deprecated) "all bits set" cpumask, defined as so:

Taking the address of such a temporary is questionable at best,
unfortunately 321a8e9d (cpumask: add CPU_MASK_ALL_PTR macro) added
CPU_MASK_ALL_PTR:
#define CPU_MASK_ALL_PTR (&CPU_MASK_ALL)
Which formalizes this practice. One day gcc could bite us over this
usage (though we seem to have gotten away with it so far).
So replace everywhere which used &CPU_MASK_ALL or CPU_MASK_ALL_PTR
with the modern "cpu_all_mask" (a real const struct cpumask *).
