Add missing checks to PS3 specific drivers ps3av and sys-manager to verify that we are actually running on a PS3 (pointed out by Arnd). Correct existing checks in other subsystems/drivers to return -ENODEV instead of zero.

At present, when an initrd is passed to the kernel used flat device tree properties, the memory the initrd occupies must also be reserved in the flat tree's reserve map, or the kernel may overwrite it. That makes life more complicated than it could be for the bootwrapper. This patch makes the kernel automatically reserve the initrd's space. That in turn requires parsing the initrd parameters earlier than they are currently, in early_init_dt_scan_chosen() instead of check_for_initrd().

At present calling lmb_reserve() (and hence lmb_add_region()) twice for exactly the same memory region will cause strange behaviour. This makes life difficult when booting from a flat device tree with memory reserve map. Which regions are automatically reserved by the kernel has changed over time, so it's quite possible a newer kernel could attempt to auto-reserve a region which is also explicitly listed in the device tree's reserve map, leading to trouble. This patch avoids the problem by making lmb_reserve() ignore a call to reserve a previously reserved region. It also removes a now redundant test designed to avoid one specific case of the problem noted above. At present, this patch deals only with duplicate reservations of an identical region. Attempting to reserve two different, but overlapping regions will still cause problems. I might post another patch later dealing with this case, but I'm avoiding it now since it is substantially more complicated to deal with, less likely to occur and more likely to indicate a genuine bug elsewhere if it does occur.

Remove interrupt-controller as a valid property under /chosen in the documentation. There is a consensus that an interrupt-controller property does not belong under /chosen. /chosen is specifically for dynamic properties set at runtime.

If something has overflowed or corrupted the stack and causes an oops, and we try to print a stack trace, that will call validate_sp, which can itself cause an oops if the cpu field of the thread_info struct at the bottom of the stack has been corrupted (if CONFIG_IRQSTACKS is set). This makes debugging harder. To avoid the second oops, this adds a check to make sure that the cpu number is reasonable before using it to check whether the stack is on the softirq or hardirq stack.

This fixes a bug caused by changes of pointer type in commit f1fda895. hose->cfg_addr type is "volatile unsigned int __iomem *", so "hose->cfg_addr + X" will not make an intended address. This patch also adds comments for usage of cfg_addr and cfg_data in pci_controller structure. We use them in irregular way, and the original code is short of explanations about them.

This reverts commit 39d61db0. The commit was buggy in multiple ways: - the conversion to ilog2() was incorrect to begin with - it tested the wrong #defines, so on all architectures but FRV you'd never see the bug except for constant arguments. - the new "get_order()" macro used its arguments multiple times, and didn't even parenthesize them properly - despite the comments, it was not true that you could use it for constant initializers, since not all architectures even use the generic page.h header file. All of the problems are individually fixable, but it all boils down to: better just revert it, and re-do it from scratch.

Based on a patch from Don Howard <dhoward@redhat.com> When calling write() with a buffer larger than 512 bytes, the driver's write buffer overflows, allowing to overwrite the EIP and execute arbitrary code with kernel privileges. In read(), there exists a similar problem, but coming from the device. A malicous or buggy device sending more than 512 bytes can overflow of the driver's read buffer, with the same effects as above.

Suspend deadlocks when trying to unregister /sys/block/sr0. This comes from Oliver's commit 94bebf4d "Driver core: fix race in sysfs between sysfs_remove_file() and read()/write()". sysfs_write_file downs buffer->sem while calling flush_write_buffer, and flushing that particular write buffer entails downing buffer->sem in orphan_all_buffers, resulting in the obvious self-deadlock.
