2008-06-12driver/char/generic_nvram: fix bannerPhilippe De Muyter
The generic nvram driver announces itself as 'Macintosh non-volatile memory driver' instead of 'Generic non-volatile memory driver'. Fix that.

Since many distros load this driver by default (throw it against the wall and see what sticks method). Change the error message severity level to avoid alarming users.

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.

2008-05-01i8k: make fan multiplier tunable with a module parameterJochen Eisinger

2008-05-01remove div_long_long_remRoman Zippel
x86 is the only arch right now, which provides an optimized for div_long_long_rem and it has the downside that one has to be very careful that the divide doesn't overflow. The API is a little akward, as the arguments for the unsigned divide are signed. The signed version also doesn't handle a negative divisor and produces worse code on 64bit archs. There is little incentive to keep this API alive, so this converts the few users to the new API.
