2007-10-25USB: empeg: clean up and handle speedsAlan Cox
The empeg is pretty fixed. Tidy up the long foo->bar->baz stuff and encode the fixed speed properly. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-10-25USB: digi_acceleport: fix termios and also readability a bitAlan Cox
- Expand some x&y to x & y so I could read it when checking - Clear CMSPAR bit in the termios (as the driver does not support it) - Encode the speed using the new tty_encode_baud_rate facility Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-10-25USB: ch341: fix termios handlingAlan Cox
The ch341 currently doesn't support most of the hardware setting. So to keep the termios data right we propogate the old termios hardware values back then encode the speed.

2007-10-25fix sg_phys to use dma_addr_tHugh Dickins
x86_32 CONFIG_HIGHMEM64G with 5GB RAM hung when booting, after issuing some "request_module: runaway loop modprobe binfmt-0000" messages in trying to exec /sbin/init. The binprm buf doesn't see the right ".ELF" header because sg_phys() is providing the wrong physical addresses for high pages: a 32-bit unsigned long is too small in this case, we need to use dma_addr_t.

2007-10-25ahci: ahci: implement workaround for ASUS P5W-DH Deluxe ↵Tejun Heo
ahci_broken_hardreset(), take #2 P5W-DH Deluxe has ICH9 which doesn't have PMP support but SIMG 4726 hardwired to the second port of AHCI controller at PCI device 1f.2. The 4726 doesn't work as PMP but as a storage processor which can do hardware RAID on downstream ports. When no device is attached to the downstream port of the 4726, pseudo ATA device for configuration appears. Unfortunately, ATA emulation on the device is very lousy and causes long hang during boot. This patch implements workaround for the board. If the mainboard is P5W-DH Deluxe (matched using DMI), only hardreset is used on the second port of AHCI controller @ 1f.2 and the hardreset doesn't depend on receiving the first FIS and just proceed to IDENTIFY. This workaround fixes bugzilla #8923. http://bugzilla.kernel.org/show_bug.cgi?id=8923 Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-10-25libata: cosmetic clean up in ata_eh_reset()Tejun Heo
Local variable @action usage in ata_eh_reset() is a bit confusing. It's used only to cache ehc->i.action to test reset masks after clearing it; however, due to the generic name "action", it's easy to misinterpret the local variable as containing the selected reset method later. Also, the reason for caching the original value is easy to miss. This patch renames @action to @tmp_action and make it buffer newly selected value instead to improve readability.

2007-10-24sched: reduce balance-tasks overheadPeter Williams
At the moment, balance_tasks() provides low level functionality for both move_tasks() and move_one_task() (indirectly) via the load_balance() function (in the sched_class interface) which also provides dual functionality. This dual functionality complicates the interfaces and internal mechanisms and makes the run time overhead of operations that are called with two run queue locks held.

2007-10-24sched: use show_regs() to improve __schedule_bug() outputSatyam Sharma
A full register dump along with stack backtrace would make the "scheduling while atomic" message more helpful. Use show_regs() instead of dump_stack() for this. We already know we're atomic in here (that is why this function was called) so show_regs()'s atomicity expectations are guaranteed. Also, modify the output of the "BUG: scheduling while atomic:" header a bit to keep task->comm and task->pid together and preempt_count() after them.

2007-10-24sched: fix sched_domain sysctl registration againMilton Miller
commit 029190c515f15f512ac85de8fc686d4dbd0ae731 (cpuset sched_load_balance flag) was not tested SCHED_DEBUG enabled as committed as it dereferences NULL when used and it reordered the sysctl registration to cause it to never show any domains or their tunables. Fixes: 1) restore arch_init_sched_domains ordering we can't walk the domains before we build them presently we register cpus with empty directories (no domain directories or files). 2) make unregister_sched_domain_sysctl do nothing when already unregistered detach_destroy_domains is now called one set of cpus at a time unregister_syctl dereferences NULL if called with a null. While the the function would always dereference null if called twice, in the previous code it was always called once and then was followed a register. So only the hidden bug of the sysctl_root_table not being allocated followed by an attempt to free it would have shown the error. 3) always call unregister and register in partition_sched_domains The code is "smart" about unregistering only needed domains. Since we aren't guaranteed any calls to unregister, always unregister. Without calling register on the way out we will not have a table or any sysctl tree. 4) warn if register is called without unregistering The previous table memory is lost, leaving pointers to the later freed memory in sysctl and leaking the memory of the tables. Before this patch on a 2-core 4-thread box compiled for SMT and NUMA, the domains appear empty (there are actually 3 levels per cpu). And as soon as two domains a null pointer is dereferenced (unreliable in this case is stack garbage): bu19a:~# ls -R /proc/sys/kernel/sched_domain/ /proc/sys/kernel/sched_domain/: cpu0 cpu1 cpu2 cpu3 /proc/sys/kernel/sched_domain/cpu0: /proc/sys/kernel/sched_domain/cpu1: /proc/sys/kernel/sched_domain/cpu2: /proc/sys/kernel/sched_domain/cpu3: bu19a:~# mkdir /dev/cpuset bu19a:~# mount -tcpuset cpuset /dev/cpuset/ bu19a:~# cd /dev/cpuset/ bu19a:/dev/cpuset# echo 0 > sched_load_balance bu19a:/dev/cpuset# mkdir one bu19a:/dev/cpuset# echo 1 > one/cpus bu19a:/dev/cpuset# echo 0 > one/sched_load_balance Unable to handle kernel paging request for data at address 0x00000018 Faulting instruction address: 0xc00000000006b608 NIP: c00000000006b608 LR: c00000000006b604 CTR: 0000000000000000 REGS: c000000018d973f0 TRAP: 0300 Not tainted (2.6.23-bml) MSR: 9000000000009032 <EE,ME,IR,DR> CR: 28242442 XER: 00000000 DAR: 0000000000000018, DSISR: 0000000040000000 TASK = c00000001912e340[1987] 'bash' THREAD: c000000018d94000 CPU: 2 ..
