Reimplement inotify_user using fsnotify. This should be feature for feature
exactly the same as the original inotify_user. This does not make any changes
to the in kernel inotify feature used by audit. Those patches (and the eventual
removal of in kernel inotify) will come after the new inotify_user proves to be
working correctly.

This patch adds the base support for the kernel memory leak
detector. It traces the memory allocation/freeing in a way similar to
the Boehm's conservative garbage collector, the difference being that
the unreferenced objects are not freed but only shown in
/sys/kernel/debug/kmemleak. Enabling this feature introduces an
overhead to memory allocations.

are submitting it upstream, make it default-disabled.

Implement the core kernel bits of Performance Counters subsystem.
The Linux Performance Counter subsystem provides an abstraction of
performance counter hardware capabilities. It provides per task and per
CPU counters, and it provides event capabilities on top of those.
Performance counters are accessed via special file descriptors.
There's one file descriptor per virtual counter used.
The special file descriptor is opened via the perf_counter_open()
system call:
int
perf_counter_open(u32 hw_event_type,
u32 hw_event_period,
u32 record_type,
pid_t pid,
int cpu);
The syscall returns the new fd. The fd can be used via the normal
VFS system calls: read() can be used to read the counter, fcntl()
can be used to set the blocking mode, etc.
Multiple counters can be kept open at a time, and the counters
can be poll()ed.
See more details in Documentation/perf-counters.txt.

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:

tracepoint part
Impact: refactor code for future changes
Current kmemtrace.h is used both as header file of kmemtrace and kmem's
tracepoints definition.
Tracepoints' definition file may be used by other code, and should only have
definition of tracepoint.
We can separate include/trace/kmemtrace.h into 2 files:
include/linux/kmemtrace.h: header file for kmemtrace
include/trace/kmem.h: definition of kmem tracepoints

Given that I have not gotten any complaints or bug reports on treercu
recently, this patch makes it be the default. There are a number of
other defconfig files that explicitly call out CLASSIC_RCU, but which
have comment headers saying not to edit them. Probably holdovers from
one of the flavors of "make config", but...

With the removal of duplicate unpack_to_rootfs() (commit
df52092f3c97788592ef72501a43fb7ac6a3cfe0) 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 cb6ff208076b5f434db1b8c983429269d719cef5 ("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
they cause vmlinux to balloon when CONFIG_KALLSYMS=y and they cause
dump_stack() and get_wchan() to produce useless information under some
circumstances.
With this we add a config option (CONFIG_STRIP_ASM_SYMS) that will cause
the build to supply -X to the linker to tell it to strip temporary local
symbols.
This doesn't seem to cause gdb any problems.

Move mqueue vfsmount plus a few tunables into the ipc_namespace struct.
The CONFIG_IPC_NS boolean and the ipc_namespace struct will serve both the
posix message queue namespaces and the SYSV ipc namespaces.
The sysctl code will be fixed separately in patch 3. After just this
patch, making a change to posix mqueue tunables always changes the values
in the initial ipc namespace.

Impact: cpuset_wq should be initialized after init_workqueues()
When I read /debugfs/tracing/trace_stat/workqueues,
I got this:
# CPU INSERTED EXECUTED NAME
# | | | |
0 0 0 cpuset
0 285 285 events/0
0 2 2 work_on_cpu/0
0 1115 1115 khelper
0 325 325 kblockd/0
0 0 0 kacpid
0 0 0 kacpi_notify
0 0 0 ata/0
0 0 0 ata_aux
0 0 0 ksuspend_usbd
0 0 0 aio/0
0 0 0 nfsiod
0 0 0 kpsmoused
0 0 0 kstriped
0 0 0 kondemand/0
0 1 1 hid_compat
0 0 0 rpciod/0
1 64 64 events/1
1 2 2 work_on_cpu/1
1 5 5 kblockd/1
1 0 0 ata/1
1 0 0 aio/1
1 0 0 kondemand/1
1 0 0 rpciod/1
I found "cpuset" is at the earliest.
I found a create_singlethread_workqueue() is earlier than
init_workqueues():
kernel_init()
->cpuset_init_smp()
->create_singlethread_workqueue()
->do_basic_setup()
->init_workqueues()
I think it's better that create_singlethread_workqueue() is called
after workqueue subsystem has been initialized.
