2007-10-17[POWERPC] ibmebus: Add device creation and bus probing based on of_deviceJoachim Fenkes
The devtree root is now searched for devices matching a built-in whitelist during boot, so these devices appear on the bus from the beginning. It is still possible to manually add/remove devices to/from the bus by using the probe/remove sysfs interface. Also, when a device driver registers itself, the devtree is matched against its matchlist. Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-10-17[POWERPC] ibmebus: Remove bus match/probe/remove functionsJoachim Fenkes
Remove old code that will be replaced by rewritten and shorter functions in the next patch. Keep struct ibmebus_dev and struct ibmebus_driver for now, but replace ibmebus_{,un}register_driver() by dummy functions. This way, the kernel will still compile and run during the transition and git bisect will be happy.

2007-10-17[POWERPC] Move of_device allocation into of_device.[ch]Joachim Fenkes
Extract generic of_device allocation code from of_platform_device_create() and move it into of_device.[ch], called of_device_alloc(). Also, there's now of_device_free() which puts the device node. This way, bus drivers that build on of_platform (like ibmebus will) can build upon this code instead of reinventing the wheel.

Turns out b868868ae0f7272228c95cc760338ffe35bb739d wasn't quite right. When called for a page that isn't marked dirty it would artificially create an alias instead of doing the obvious thing and access the page via KSEG0. The same issue also exists in copy_to_user_page and copy_from_user_page which was causing the machine to die under rare circumstances for example when running ps if the BUG_ON() assertion added by the earlier fix was getting triggered.

2007-10-16uml: definitively kill subprocesses on panicLepton Wu
In a stock 2.6.22.6 kernel, poweroff a user mode linux guest (2.6.22.6 running in skas0 mode) will halt the host linux. I think the reason is the kernel thread abort because of a bug. Then the sys_reboot in process of user mode linux guest is not trapped by the user mode linux kernel and is executed by host. I think it is better to make sure all of our children process to quit when user mode linux kernel abort.

2007-10-16uml: fix stub address calculationsJeff Dike
The calculation of CONFIG_STUB_CODE and CONFIG_STUB_DATA didn't take into account anything but 3G/1G and 2G/2G, leaving the other vmsplits out in the cold. I'd rather not duplicate the four known host vmsplit cases for each of these symbols. I'd also like to calculate them based on the highest userspace address. The Kconfig language seems not to allow calculation of hex constants, so I moved this to as-layout.h. CONFIG_STUB_CODE, CONFIG_STUB_DATA, and CONFIG_STUB_START are now gone. In their place are STUB_CODE, STUB_DATA, and STUB_START in as-layout.h. i386 and x86_64 seem to differ as to whether an unadorned constant is an int or a long, so I cast them to unsigned long so they can be printed consistently. However, they are also used in stub.S, where C types don't work so well. So, there are ASM_ versions of these constants for use in stub.S. I also ifdef-ed the non-asm-friendly portion of as-layout.h. With this in place, most of the rest of this patch is changing CONFIG_STUB_* to STUB_*, except in stub.S, where they are changed to ASM_STUB_*. defconfig has the old symbols deleted. I also print these addresses out in case there is any problem mapping them on the host. The two stub.S files had some trailing whitespace, so that is cleaned up here.

2007-10-16uml: correctly handle skb allocation failuresJeff Dike
Handle memory allocation failures when reading packets. We have to read something from the host, even if we can't allocate any memory. If we don't, the host side of the device may fill up and stop delivering interrupts because no new packets can be queued. A single sk_buff is allocated whenever an MTU is seen which is larger than any seen earlier. This is used to read packets if there is a memory allocation failure. The large MTU check is done from eth_configure, which is called when a interface is added to the system.
