* layered parport code uses parport->devDavid Brownell2007-05-08
| | | | | | | | | | | | | | | | | | | Update some of the layered parport_driver code to use parport->dev: - i2c-parport (parent of i2c_adapter) - spi_butterfly (parent of spi_master, allowing cruft removal) - lp (creating class_device) - ppdev (parent of parportN device) - tipar (creating class_device) There are still drivers that should be updated, like some of the input drivers; but they won't be any worse off than they are today.

* move die notifier handling to common codeChristoph Hellwig2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | 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.

* tty: introduce no_tty and use it in selinuxEric W. Biederman2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | 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.h Signed-off-by: Eric W.

* tty: simplify calling of put_pid.Eric W. Biederman2007-05-08
| | | | | | | | | | | | | | | | 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.

* Fixes and cleanups for earlyprintk aka boot consoleGerd Hoffmann2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* fix cyclades.h for x86_64 (and probably others)Klaus Kudielka2007-05-08
| | | | | | | | | | | | | | | | 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.

* Use stop_machine_run in the Intel RNG driverPrarit Bhargava2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | 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).

* ipmi: allow shared interruptsCorey Minyard2007-05-08

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.

| * | [PATCH] x86: fix amd64-agp aperture validationJan Beulich2007-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under CONFIG_DISCONTIGMEM, assuming that a !pfn_valid() implies all subsequent pfn-s are also invalid is wrong. Thus replace this by explicitly checking against the E820 map.
