This removes some leftover code that was in #if 0 in the console autodetect code. It also adds passing of the default serial speed as console options when it is available from Open Firmware. Signed-off-by:

This improves the config space access routines on G5, by adding a generic helper function to locate the pci_controller structure (to be used by an upcoming new platform too) and cleaning up the pmac routines. It includes the fix to skip devices that aren't present in the OF tree that is necessary for newer G5 desktop models. Signed-off-by:

This patch adds proper __iomem annotations to the remaning IO macros on ppc64, and removes now useless casts from eeh.h. This fixes the sparse warnings in mpic.c among others. I need to do an equivalent things for ppc32 (though I think viro did some of it already) and fix users. Signed-off-by:

The pktcdvd driver uses kunmap_atomic() incorrectly. The function is supposed to take an address as the first parameter, but the pktcdvd driver passed a page pointer. Thanks to Douglas Gilbert and Jens Axboe for discovering this. Signed-off-by:

hugetlb_get_unmapped_area() fails to find an unmapped area while unmapped area is huge. That's because hugetlb_get_unmapped_area just searches forward from mm->free_area_cache. If reaching TASK_SIZE, it does not go back to TASK_UNMAPPED_BASE, just returns -ENOMEM. 1) Add a specific hugetlb_get_unmapped_area on i386. 2) Generic hugetlb_get_unmapped_area is also fixed.

On some platforms (e.g. SGI Challenge, Origin, and Altix machines), writes to I/O space aren't ordered coming from different CPUs. For the most part, this isn't a problem since drivers generally spinlock around code that does writeX calls, but if the last operation a driver does before it releases a lock is a write and some other CPU takes the lock and immediately does a write, it's possible the second CPU's write could arrive before the first's. This patch adds a mmiowb() call to deal with this sort of situation, and adds some documentation describing I/O ordering issues to deviceiobook.tmpl. The idea is to mirror the regular, cacheable memory barrier operation, wmb. Example of the problem this new macro solves: CPU A: spin_lock_irqsave(&dev_lock, flags) CPU A: ... CPU A: writel(newval, ring_ptr); CPU A: spin_unlock_irqrestore(&dev_lock, flags) ... CPU B: spin_lock_irqsave(&dev_lock, flags) CPU B: writel(newval2, ring_ptr); CPU B: ... CPU B: spin_unlock_irqrestore(&dev_lock, flags) In this case, newval2 could be written to ring_ptr before newval. Fixing it is easy though: CPU A: spin_lock_irqsave(&dev_lock, flags) CPU A: ... CPU A: writel(newval, ring_ptr); CPU A: mmiowb(); /* ensure no other writes beat us to the device */ CPU A: spin_unlock_irqrestore(&dev_lock, flags) ... CPU B: spin_lock_irqsave(&dev_lock, flags) CPU B: writel(newval2, ring_ptr); CPU B: ... CPU B: mmiowb(); CPU B: spin_unlock_irqrestore(&dev_lock, flags) Note that this doesn't address a related case where the driver may want to actually make a given write get to the device before proceeding. This should be dealt with by immediately reading a register from the card that has no side effects. According to the PCI spec, that will guarantee that all writes have arrived before being sent to the target bus. If no such register is available (in the case of card resets perhaps), reading from config space is sufficient (though it may return all ones if the card isn't responding to read cycles). I've tried to describe how mmiowb() differs from PCI posted write flushing in the patch to deviceiobook.tmpl. Signed-off-by:Jesse Barnes <jbarnes@sgi.com> Signed-off-by:

idr_remove() should fail gracefully and warn if the id being removed is not valid. The attached patch should do the job without additional overhead. With the existing code, removing an id which was not allocated could remove a valid id which shares the same lowest layer of the radix tree. I ran a kernel with this patch but have not done any tests to force a failure. Signed-off-by:

This is needed for an mmtimer driver update that we are currently working on. The mmtimer driver provides CLOCK_SGI_CYCLE via clock_gettime and clock_settime. With this api fix one will be able to use timer_create, timer_settime and friends from userspace to schedule and receive signals via timer interrupts of mmtimer. Changelog * Clean up timer api for drivers that use register_posix_clock. Drivers will then be able to use posix timers to schedule interrupts. * Change API for posix_clocks[].timer_create to only pass one pointer to a k_itimer structure that is now allocated and managed by the posix layer in the same way as for the other posix timer functions. * Isolate a posix_timer_event(timr) function in posix-timers.c that may be called by the interrupt routine of a timer to signal that the scheduled event has taken place.

This patch against 2.6.9 adds a DAC ownership check to the existing MAC permission checks when setting the security.selinux attribute via setxattr. In the past, the MAC permission checks were viewed as sufficient for controlling relabeling operations, but experience in the Fedora SELinux integration has shown that a DAC check is also appropriate here, particularly under targeted policy.

As noticed by Joey Hess (and thanks for Christoph for forwarding it). Also requirements from Werner Almesberger. If someone passes 'foo="some value"' the param engine removes the quotes and hands 'foo' and 'some value'. The __setup() parameters expect a single string, and so we try to regenerate it from the two parts. Finally, we try to place it as an environment variable. Werner wants quotes stripped out of the environment variable. It makes sense to do that for __setup, too (so it sees 'foo=some value'), since __setup functions don't usually handle quotes.

Currently, only module parameters in loaded modules are exported in /sys/modules/, while those of "modules" built into the kernel can be set by the kernel command line, but not read or set via sysfs. - move module parameters from /sys/modules/$(module_name)/$(parameter_name) to /sys/modules/$(module_name)/parameters/$(parameter_name) - remove dummy kernel_param for exporting refcnt, add "struct module *"-based attribute instead - also export module paramters for "modules" which are built into the kernel, so parameters are always accessible at /sys/modules/$(KBUILD_MODNAME)/$(parameter_name) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (modified) Signed-off-by:
