module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.Signed-off-by: Rusty Russell

not protect pages, what is not what we want with

This patch fixes a lockdep warning on ARM platforms:
[ 0.000000] WARNING: lockdep init error! Arch code didn't call lockdep_init() early enough?
[ 0.000000] Call stack leading to lockdep invocation was:
[ 0.000000] [] save_stack_trace_tsk+0x0/0x90
[ 0.000000] [] 0xffffffffThe warning is caused by printk inside smp_setup_processor_id().
It is safe to do this because lockdep_init() doesn't depend on
smp_setup_processor_id(), so improve things that printk can be
called as early as possible without lockdep complaint.Signed-off-by: Ming Lei

The user may use "foo-bar" for a kernel parameter defined as "foo_bar".
Make sure it works the other way around too.Apply the equality of dashes and underscores on early_params and __setup

this is the intended behaviour.With the patch the kernel accepts "log-buf-len=1M" as expected.

Commit d5767c53535a ("bootup: move 'usermodehelper_enable()' to the end
of do_basic_setup()") moved 'usermodehelper_enable()' to end of
do_basic_setup() to after the initcalls. But then I get failed to let
uvesafb work on my computer, and lose the splash boot.So maybe we could start usermodehelper_enable a little early to make
some task work that need eary init with the help of user mode.[ I would *really* prefer that initcalls not call into user space - even
the real 'init' hasn't been execve'd yet, after all! But for uvesafb
it really does look like we don't have much choice.I considered doing this when we mount the root filesystem, but
depending on config options that is in multiple places. We could do
the usermode helper enable as a rootfs_initcall()..So I'm just using wang yanqing's trivial patch. It's not wonderful,
but it's simple and should work. We should revisit this some day,
though. - Linus ]Signed-off-by: Linus Torvalds

Doing it just before starting to call into cpu_idle() made a sick kind
of sense only because the original bug we fixed (see commit
288d5abec831: "Boot up with usermodehelper disabled") was about problems
with some scheduler data structures not being initialized, and they had
better be initialized at that point.But it really didn't make any other conceptual sense, and doing it after
the initial "schedule()" call for the idle thread actually opened up a
race: what if the main initialization thread did everything without
needing to sleep, and got all the way into user land too? Without
actually having scheduled back to the idle thread?Now, in normal circumstances that doesn't ever happen, but it looks like
Richard Cochran triggered exactly that on his ARM IXP4xx machines:"I have some ARM IXP4xx based machines that use the two on chip MAC
ports (aka NPEs). The NPE needs a firmware in order to function.
Ever since the following commit [that 288d5abec831 one], it is no
longer possible to bring up the interfaces during the init scripts."with a call trace showing an ioctl coming from user space. Richard says:
"The init is busybox, and the startup script does mount, syslogd, and
then ifup, so that all can go by quickly."The fix is to move the usermodehelper_enable() into the main 'init'
thread, and just put it after we've done all our initcalls. By then,
everything really should be up, but we've obviously not actually started
the user-mode portion of init yet.Reported-and-tested-by: Richard Cochran

The core device layer sends tons of uevent notifications for each device
it finds, and if the kernel has been built with a non-empty
CONFIG_UEVENT_HELPER_PATH that will make us try to execute the usermode
helper binary for all these events very early in the boot.Not only won't the root filesystem even be mounted at that point, we
literally won't have necessarily even initialized all the process
handling data structures at that point, which causes no end of silly
problems even when the usermode helper doesn't actually succeed in
executing.So just use our existing infrastructure to disable the usermodehelpers
to make the kernel start out with them disabled. We enable them when
we've at least initialized stuff a bit.Problems related to an uninitialized

There is a problem that kdump(2nd kernel) sometimes hangs up due
to a pending IPI from 1st kernel. Kernel panic occurs because IPI
comes before call_single_queue is initialized.To fix the crash, rename init_call_single_data() to call_function_init()
and call it in start_kernel() so that call_single_queue can be
initialized before enabling interrupts.The details of the crash are:
(1) 2nd kernel boots up
(2) A pending IPI from 1st kernel comes when irqs are first enabled
in start_kernel().(3) Kernel tries to handle the interrupt, but call_single_queue
is not initialized yet at this point. As a result, in the
generic_smp_call_function_single_interrupt(), NULL pointer
dereference occurs when list_replace_init() tries to access
&q->list.next.Therefore this patch changes the name of init_call_single_data()
to call_function_init() and calls it before local_irq_enable()
in start_kernel().Signed-off-by: Takao Indoh

cpumask_t is very big struct and cpu_vm_mask is placed wrong position.
It might lead to reduce cache hit ratio.This patch has two change.
1) Move the place of cpumask into last of mm_struct. Because usually cpumask
is accessed only front bits when the system has cpu-hotplug capability
2) Convert cpu_vm_mask into cpumask_var_t. It may help to reduce memory
footprint if cpumask_size() will use nr_cpumask_bits properly in future.In addition, this patch change the name of cpu_vm_mask with cpu_vm_mask_var.
It may help to detect out of tree cpu_vm_mask users.This patch has no functional change.

During early boot, local IRQ is disabled until IRQ subsystem is
properly initialized. During this time, no one should enable
local IRQ and some operations which usually are not allowed with
IRQ disabled, e.g. operations which might sleep or require
communications with other processors, are allowed.lockdep tracked this with early_boot_irqs_off/on() callbacks.
As other subsystems need this information too, move it to
init/main.c and make it generally available. While at it,
toggle the boolean to early_boot_irqs_disabled instead of
enabled so that it can be initialized with %false and %true
indicates the exceptional condition.Signed-off-by: Tejun Heo

The call to flush_scheduled_work() in do_initcalls() is there to make
sure all works queued to system_wq by initcalls finish before the init
sections are dropped.However, the call doesn't make much sense at this point - there
already are multiple different workqueues and different subsystems are
free to create and use their own. Ordering requirements are and
should be expressed explicitly.Drop the call to prepare for the deprecation and removal of
flush_scheduled_work().Andrew suggested adding sanity check where the workqueue code checks
whether any pending or running work has the work function in the init
text section. However, checking this for running works requires the
worker to keep track of the current function being executed, and
checking only the pending works will miss most cases. As a violation
will almost always be caught by the usual page fault mechanism, I
don't think it would be worthwhile to make the workqueue code track
extra state just for this.Signed-off-by: Tejun Heo

Make do_execve() take a const filename pointer so that kernel_execve() compiles
correctly on ARM:arch/arm/kernel/sys_arm.c:88: warning: passing argument 1 of 'do_execve' discards qualifiers from pointer target type
This also requires the argv and envp arguments to be consted twice, once for
the pointer array and once for the strings the array points to. This is
because do_execve() passes a pointer to the filename (now const) to
copy_strings_kernel(). A simpler alternative would be to cast the filename
pointer in do_execve() when it's passed to copy_strings_kernel().do_execve() may not change any of the strings it is passed as part of the argv
or envp lists as they are some of them in .rodata, so marking these strings as
const should be fine.Further kernel_execve() and sys_execve() need to be changed to match.
This has been test built on x86_64, frv, arm and mips.
