This patch moves the die notifier handling to common code. Previous
various architectures had exactly the same code for it. Note that the new
code is compiled unconditionally, this should be understood as an appel to
the other architecture maintainer to implement support for it aswell (aka
sprinkling a notify_die or two in the proper place)arm had a notifiy_die that did something totally different, I renamed it to
arm_notify_die as part of the patch and made it static to the file it's
declared and used at. avr32 used to pass slightly less information through
this interface and I brought it into line with the other architectures.[akpm@linux-foundation.org: build fix]

While researching the tty layer pid leaks I found a weird case in selinux when
we drop a controlling tty because of inadequate permissions we don't do the
normal hangup processing. Which is a problem if it happens the session leader
has exec'd something that can no longer access the tty.We already have code in the kernel to handle this case in the form of the
TIOCNOTTY ioctl. So this patch factors out a helper function that is the
essence of that ioctl and calls it from the selinux code.This removes the inconsistency in handling dropping of a controlling tty and
who knows it might even make some part of user space happy because it received
a SIGHUP it was expecting.In addition since this removes the last user of proc_set_tty outside of
tty_io.c proc_set_tty is made static and removed from tty.hSigned-off-by: Eric W. Biederman

This patch should contain no functional changes.
At some point I got confused and thought put_pid could not be called while a
spin lock was held. While it may be nice to avoid that to reduce lock hold
times put_pid can be safely called while we hold a spin lock.This patch removes all of the complications from the code introduced by my
misunderstanding, making the code a little more readable.Signed-off-by: Eric W. Biederman

The console subsystem already has an idea of a boot console, using the
CON_BOOT flag. The implementation has some flaws though. The major
problem is that presence of a boot console makes register_console() ignore
any other console devices (unless explicitly specified on the kernel
command line).This patch fixes the console selection code to *not* consider a boot
console a full-featured one, so the first non-boot console registering will
become the default console instead. This way the unregister call for the
boot console in the register_console() function actually triggers and the
handover from the boot console to the real console device works smoothly.
Added a printk for the handover, so you know which console device the
output goes to when the boot console stops printing messages.The disable_early_printk() call is obsolete with that patch, explicitly
disabling the early console isn't needed any more as it works automagically
with that patch.I've walked through the tree, dropped all disable_early_printk() instances
found below arch/ and tagged the consoles with CON_BOOT if needed. The
code is tested on x86, sh (thanks to Paul) and mips (thanks to Ralf).Changes to last version: Rediffed against -rc3, adapted to mips cleanups by
Ralf, fixed "udbg-immortal" cmd line arg on powerpc.Signed-off-by: Gerd Hoffmann

The jsm driver doesn't currently use the uart_handle_*_change helper
functions, which are the obvious place for things like linuxpps to tie
into (which it now does of course), and as a result the jsm driver can
not be used with linuxpps and anything else that ties into the
serial_core helper functions. This patch adds calls to these helper
functions whenever the value they manage changes. That actual storage
of the state is not modified since the jsm driver caches the current
settings (The 8250 driver reads them everytime a user asks for the
state), and only updates them whenever they change.Signed-off-by: Len Sorensen

The jsm driver fails when you try to use the TIOCSSERIAL ioctl. The reason
is that the driver never sets uart_port.uartclk, causing the data received
using TIOCGSERIAL to not match the internal state of the driver. This
patch fixes this problem by settings the uartclk to the value used by the
serial_core (16 times the baud base).Signed-off-by: Len Sorensen

Switch from private uclong, etc over to standard types.
Signed-off-by: Andrew Morton
Signed-off-by: Linus Torvalds -
At least on x86_64 the present cyclades.h is broken due to the wrong size
of uclong. This affects, of course, both the kernel and the user-level
utilities. The symptom is that cyzload refuses to load the firmware. I
also managed to freeze the machine when unloading the module.The patch below fixes this in an architecture-independent way. I have
tested it with 2.6.19 and the driver works fine again with a Cyclades-Z on
an Athlon 64 X2.[akpm@linux-foundation.org: fix warnings]

PNP now initializes device dma masks, which prevents oopses when generic
dma calls are made using pnp device nodes.This assumes PNP only uses ISA DMA, with 24 bit addresses; and that it's
safe to init those masks for all devices (rather than finding out which
devices have been assigned DMA channels, and handling only those).Signed-off-by: David Brownell

Replace call_smp_function with stop_machine_run in the Intel RNG driver.
CPU A has done read_lock(&lock)
CPU B has done write_lock_irq(&lock) and is waiting for A to release the lock.A third CPU calls call_smp_function and issues the IPI. CPU A takes CPU
C's IPI. CPU B is waiting with interrupts disabled and does not see the
IPI. CPU C is stuck waiting for CPU B to respond to the IPI.Deadlock.
The solution is to use stop_machine_run instead of call_smp_function
(call_smp_function should not be called in situations where the CPUs may be
suspended).[haruo.tomita@toshiba.co.jp: fix a typo in mod_init()]

The IPMI driver used enable_irq and disable_irq when it got into situations
where it couldn't allocate memory; it did this to avoid having the interrupt
just lock the machine when it couldn't get memory to perform the transaction
to disable the interrupt.This patch modifies the driver to not use disable_irq and enable_irq. It
instead sends the messages to the BMC to perform this operation. It also
makes sure interrupts are cleanly disabled when the interface is shut down and
cleans up some shutdown things that are no longer necessary.Signed-off-by: Corey Minyard
