Commit 0031a06e converted all of the USB drivers to use dev_set_name(), though there was a typo on the m66592-udc conversion that handed off the wrong pointer (we want the struct device here obviously, not the struct usb_gadget). Signed-off-by:

commit fb6624eb (initrd: Fix virtual/physical mix-up in overwrite test) introduced the compiler warning below on mips, as its virt_to_page() doesn't cast the passed address to unsigned long internally, unlike on most other architectures: init/main.c: In function `start_kernel': init/main.c:633: warning: passing argument 1 of `virt_to_phys' makes pointer from integer without a cast init/main.c:636: warning: passing argument 1 of `virt_to_phys' makes pointer from integer without a cast For now, kill the warning by explicitly casting initrd_start to `void *', as that's the type it should really be.

Paul pointed out two incorrect read barriers in the marker handler code in the path where multiple probes are connected. Those are ordering reads of "ptype" (single or multi probe marker), "multi" array pointer, and "multi" array data access. It should be ordered like this : read ptype smp_rmb() read multi array pointer smp_read_barrier_depends() access data referenced by multi array pointer The code with a single probe connected (optimized case, does not have to allocate an array) has correct memory ordering. It applies to kernel 2.6.26.x, 2.6.25.x and linux-next. Signed-off-by:

The mutex is released on a successful return, so it would seem that it should be released on an error return as well. The semantic patch finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression l; @@ mutex_lock(l); ... when != mutex_unlock(l) when any when strict ( if (...) { ... when != mutex_unlock(l) + mutex_unlock(l); return ...; } | mutex_unlock(l); ) // </smpl> Signed-off-by:

When multiple cpusets are overlapping in their 'cpus' and hence they form a single sched domain, the largest sched_relax_domain_level among those should be used. But when top_cpuset's sched_load_balance is set, its sched_relax_domain_level is used regardless other sub-cpusets'. This patch fixes it by walking the cpuset hierarchy to find the largest sched_relax_domain_level. Signed-off-by:

All child cpusets contain a subset of the parent's cpus, so we can skip them when partitioning sched domains. This decreases 'csa' greately for cpusets with multi-level hierarchy. Signed-off-by:

On HPPA there exists some older GSC graphics cards, which need special graphic-card-BIOS patching to become supported. Since we don't have yet implemented the patching, it's better to detect such cards in advance, inform to the user that there are known problems and to not activate the card. Problematic GSC cards and BIOS versions are: * Hyperdrive/Hyperbowl (A4071A) graphics card series: * ID = 0x2BCB015A (Version 8.04/8) * ID = 0x2BCB015A (Version 8.04/11) * Thunder 1 VISUALIZE 48 card: * ID = 0x2F23E5FC (Version 8.05/9) * Thunder 2 VISUALIZE 48 XP card: * ID = 0x2F8D570E (Version 8.05/12) * Some Hyperion and ThunderHawk GSC cards Further details are described here: http://parisc-linux.org/faq/graphics-howto.htmlSigned-off-by:
