2006-07-29V4L/DVB (4323): [budget/budget-av/budget-ci/budget-patch drivers] fixed DMA ↵Oliver Endriss
start/stop code Fix bug reported by Andrew de Quincey: After cold boot the saa7146 DMA did not start if the demuxer was opened before the frontend has locked to the signal. DMA transfers will be started now if (and only if) the frontend is locked and data should be sent to the demuxer.

2006-07-29V4L/DVB (4316): Check __must_check warningsMichael Krufky
Check __must_check warnings for class_device_register and class_device_create_file video_device_create_file was declared as a void, but instead should return the int value of class_device_create_file. Move the check from bttv-driver.c into v4l2-dev.h, because all other callers of video_device_create_file must also be checked. Replace the call to class_device_create_file in videodev.c with video_device_create_file, as defined in v4l2-dev.h, so that the return value of class_device_create_file will be checked. Check the return value of class_device_register in videodev.c and pvrusb2-sysfs.c Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-07-29V4L/DVB (4314): Set the Auxiliary Byte when tuning LG H06xF in analog modeMichael Krufky
With the LG H06xF tuners, an auxiliary byte must be sent after the standard four-byte i2c sequence. The code that does this is currently in the wrong place, causing random bytes to be written to the tuner over i2c in the set_type function.

2006-07-29V4L/DVB (4292): Fix DISEQC regressionAndrew de Quincey
The changes to add frontend reinitialisation moved the position where the init() op is called into the frontend thread. Unfortunately, since DISEQC operations do not use the frontend thread, this meant that DISEQC could be called against an uninitalised frontend, leading to all sorts of trouble. Patch fixes this by reinstating the original fronted intialisation call. Signed-off-by: Andrew de Quincey <adq_dvb@lidskialf.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-07-29V4L/DVB (4291): Add dvbpll i2c device check.Andrew de Quincey
Some cards have multiple possible addresses for their PLLs, with no other way to tell if a PLL is present or not apart from probing to see if an i2c device is present.

Patch from Lennert Buytenhek The IOP 80219 xscale CPU is a stripped down version of the IOP32x. But the fact that the 80219 and IOP32x are very similar doesn't mean that they need to share a cpu table entry. It's also somewhat confusing for the end user to see the 80219 reported as an IOP32x, so this patch splits the IOP32x cpu table entry to make a separate entry for the 80219.

2006-07-28[PATCH] pi-futex: robust-futex exitIngo Molnar
Fix robust PI-futexes to be properly unlocked on unexpected exit. For this to work the kernel has to know whether a futex is a PI or a non-PI one, because the semantics are different. Since the space in relevant glibc data structures is extremely scarce, the best solution is to encode the 'PI' information in bit 0 of the robust list pointer. Existing (non-PI) glibc robust futexes have this bit always zero, so the ABI is kept. New glibc with PI-robust-futexes will set this bit.

2006-07-28[PATCH] x86_64: Dump leftover backtrace entries when dwarf2 unwinder got stuckAndi Kleen
The dwarf2 unwinder currently often gets stuck because a lot of assembly code doesn't have proper dwarf2 annotiation yet. This currently often happens with __down. Should fix this by adding proper dwarf2 annotation to all inline assembly. However until that's done we need a quick fix for 2.6.18 to avoid incomplete backtraces. So when this happens dump the rest of the stack with the old unwinder instead of silently not dumping it. There was already a optional "both" mode that dumped both, but that was too ugly. I also clarified the headers for the different backtraces a bit. Also add a clear error message for missing dwarf2 annotation that people can work on. And I removed a dead variable left over from Ingo's changes. Cc: mingo@elte.hu Cc: jbeulich@novell.com Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-07-28[PATCH] x86_64: Enlarge debug stack for nested kprobesbibo mao
In x86_64 platform, INT1 and INT3 trap stack is IST stack called DEBUG_STACK, when INT1/INT3 trap happens, system will switch to DEBUG_STACK by hardware. Current DEBUG_STACK size is 4K, when int1/int3 trap happens, kernel will minus current DEBUG_STACK IST value by 4k. But if int3/int1 trap is nested, it will destroy other vector's IST stack. This patch modifies this, it sets DEBUG_STACK size as 8K and allows two level of nested int1/int3 trap. Kprobe DEBUG_STACK may be nested, because kprobe handler may be probed by other kprobes. Thanks jbeulich for pointing out error in the first patch. [AK: nested kprobes are pretty dubious. Hopefully one nest will be enough. This will cost 8K per CPU (4K more than before)] Signed-off-by: bibo, mao <bibo.mao@intel.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-07-28[PATCH] x86_64: Don't clobber r8-r11 in int 0x80 handlerAndi Kleen
When int 0x80 is called from long mode r8-r11 would leak out of the kernel (or rather they would be filled with some values from the kernel stack). I don't think it's a security issue because the values come from the fixed stack frame which should be near always user registers from a previous interrupt. Still better fix it. Longer term the register save macros need to be cleaned up to avoid such mistakes in the future. Original analysis from Richard Brunner, fix by me.

2006-07-28[PATCH] i386/x86-64: Add user_mode checks to profile_pc for oprofileAndi Kleen
Fixes a obscure user space triggerable crash during oprofiling. Oprofile calls profile_pc from NMIs even when user_mode(regs) is not true and the program counter is inside the kernel lock section. This opens a race - when a user program jumps to a kernel lock address and a NMI happens before the illegal page fault exception is raised and the program has a unmapped esp or ebp then the kernel could oops. NMIs have a higher priority than exceptions so that could happen. Add user_mode checks to i386/x86-64 profile_pc to prevent that.

2006-07-29[POWERPC] force 64bit mode in fwnmi handlers to workaround firmware bugsOlaf Hering
The firmware of POWER4 and JS20 systems does not switch the cpu to 64bit mode when the registered system_reset and machine_check handlers get called. If a 32bit process runs on that cpu at the time of the event, the cpu remains in 32bit mode. xmon and kdump can not deal with it, the result is an error like 'Bad kernel stack pointer fff2aad0 at 3200'. xmon just loses some register info, but booting the kdump kernel usually fails.
