2008-06-19agp: two-stage page destruction issueJan Beulich
besides it apparently being useful only in 2.6.24 (the changes in 2.6.25 really mean that it could be converted back to a single-stage mechanism), I'm seeing an issue in Xen Dom0 kernels, which is caused by the calling of gart_to_virt() in the second stage invocations of the destroy function. I think that besides this being a real issue with Xen (where unmap_page_from_agp() is not just a page table attribute change), this also is invalid from a theoretical perspective: One should not assume that gart_to_virt() is still valid after unmapping a page. So minimally (keeping the 2-stage mechanism) a patch like the one below would be needed. Jan Signed-off-by: Dave Airlie <airlied@redhat.com>

2008-06-13drm: use drms ioctl cmd not what we get passed from userspace.Johannes Weiner

2008-06-12rtc: make HPET_RTC_IRQ track HPET_EMULATE_RTCDavid Brownell
More Kconfig tweaks related to the legacy PC RTC code: - Describe the legacy PC RTC driver as such ... it's never quite been clear that this driver is for PC RTCs, and now it's fair to call this the "legacy" driver. - Force it to understand about HPET stealing its IRQs ... kernel code does this always when HPET is in use, there should be no option for users to goof up the config. This seems to fix kernel bugzilla #10729.

2008-06-06ipwireless: Fix blocked sendingDavid Sterba
Packet sending is driven by two flags, tx_ready and tx_queued. It was possible, that there were queued data for sending and hardware was flagged as blocked but in fact it was not. The tx_queued was indicator but should be really a counter else first fragmented packet resets tx_queued flag, but there may be pending packets which do not get sent. New semantics: tx_ready - set, if hw is ready to send packet, no packet is being transferred right now set the flag right at the place where data are copied into hw memory and not earlier without checking if it was succesful tx_queued - count of enqueued packets, including fragments Tested-by: Michal Rokos <michal.rokos@gmail.com> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-05-30virtio: An entropy device, as suggested by hpa.Rusty Russell
Note that by itself, having a "hardware" random generator does very little: you should probably run "rngd" in your guest to feed this into the kernel entropy pool. Included: virtio_rng: dont use vmalloced addresses for virtio If virtio_rng is build as a module, random_data is an address in vmalloc space. As virtio expects guest real addresses, this can cause any kind of funny behaviour, so lets allocate random_data dynamically with kmalloc.

2008-05-20sparc64: Add global register dumping facility.David S. Miller
When a cpu really is stuck in the kernel, it can be often impossible to figure out which cpu is stuck where. The worst case is when the stuck cpu has interrupts disabled. Therefore, implement a global cpu state capture that uses SMP message interrupts which are not disabled by the normal IRQ enable/disable APIs of the kernel. As long as we can get a sysrq 'y' to the kernel, we can get a dump. Even if the console interrupt cpu is wedged, we can trigger it from userspace using /proc/sysrq-trigger The output is made compact so that this facility is more useful on high cpu count systems, which is where this facility will likely find itself the most useful :) Signed-off-by: David S.
