2010-10-14Un-inline the core-dump helper functionsLinus Torvalds2-32/+40
Tony Luck reports that the addition of the access_ok() check in commit 0eead9ab41da ("Don't dump task struct in a.out core-dumps") broke the ia64 compile due to missing the necessary header file includes. Rather than add yet another include (<asm/unistd.h>) to make everything happy, just uninline the silly core dump helper functions and move the bodies to fs/exec.c where they make a lot more sense. dump_seek() in particular was too big to be an inline function anyway, and none of them are in any way performance-critical. And we really don't need to mess up our include file headers more than they already are.

2010-10-14Don't dump task struct in a.out core-dumpsLinus Torvalds3-22/+6
akiphie points out that a.out core-dumps have that odd task struct dumping that was never used and was never really a good idea (it goes back into the mists of history, probably the original core-dumping code). Just remove it. Also do the access_ok() check on dump_write(). It probably doesn't matter (since normal filesystems all seem to do it anyway), but he points out that it's normally done by the VFS layer, so ... [ I suspect that we should possibly do "vfs_write()" instead of calling ->write directly. That also does the whole fsnotify and write statistics thing, which may or may not be a good idea. ] And just to be anal, do this all for the x86-64 32-bit a.out emulation code too, even though it's not enabled (and won't currently even compile) Reported-by: akiphie <akiphie@lavabit.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2010-10-13ioat2: fix performance regressionDan Williams1-1/+1
Commit 0793448 "DMAENGINE: generic channel status v2" changed the interface for how dma channel progress is retrieved. It inadvertently exported an internal helper function ioat_tx_status() instead of ioat_dma_tx_status(). The latter polls the hardware to get the latest completion state, while the helper just evaluates the current state without touching hardware. The effect is that we end up waiting for completion timeouts or descriptor allocation errors before the completion state is updated. iperf (before fix): [SUM] 0.0-41.3 sec 364 MBytes 73.9 Mbits/sec iperf (after fix): [SUM] 0.0- 4.5 sec 499 MBytes 940 Mbits/sec This is a regression starting with 2.6.35.

2010-10-13net: allow FEC driver to use fixed PHY supportGreg Ungerer1-14/+27
At least one board using the FEC driver does not have a conventional PHY attached to it, it is directly connected to a somewhat simple ethernet switch (the board is the SnapGear/LITE, and the attached 4-port ethernet switch is a RealTek RTL8305). This switch does not present the usual register interface of a PHY, it presents nothing. So a PHY scan will find nothing - it finds ID's of 0 for each PHY on the attached MII bus. After the FEC driver was changed to use phylib for supporting PHYs it no longer works on this particular board/switch setup. Add code support to use a fixed phy if no PHY is found on the MII bus. This is based on the way the cpmac.c driver solved this same problem. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-10-12ARM: 6440/1: ep93xx: DMA: fix channel_disableMika Westerberg1-1/+1
When channel_disable() is called, it disables per channel interrupts and waits until channels state becomes STATE_STALL, and then disables the channel. Now, if the DMA transfer is disabled while the channel is in STATE_NEXT we will not wait anything and disable the channel immediately. This seems to cause weird data corruption for example in audio transfers. Fix is to wait while we are in STATE_NEXT or STATE_ON and only then disable the channel.

2010-10-12ring-buffer: Fix typo of time extends per pageSteven Rostedt1-1/+1
Time stamps for the ring buffer are created by the difference between two events. Each page of the ring buffer holds a full 64 bit timestamp. Each event has a 27 bit delta stamp from the last event. The unit of time is nanoseconds, so 27 bits can hold ~134 milliseconds. If two events happen more than 134 milliseconds apart, a time extend is inserted to add more bits for the delta. The time extend has 59 bits, which is good for ~18 years. Currently the time extend is committed separately from the event. If an event is discarded before it is committed, due to filtering, the time extend still exists. If all events are being filtered, then after ~134 milliseconds a new time extend will be added to the buffer. This can only happen till the end of the page. Since each page holds a full timestamp, there is no reason to add a time extend to the beginning of a page. Time extends can only fill a page that has actual data at the beginning, so there is no fear that time extends will fill more than a page without any data. When reading an event, a loop is made to skip over time extends since they are only used to maintain the time stamp and are never given to the caller. As a paranoid check to prevent the loop running forever, with the knowledge that time extends may only fill a page, a check is made that tests the iteration of the loop, and if the iteration is more than the number of time extends that can fit in a page a warning is printed and the ring buffer is disabled (all of ftrace is also disabled with it). There is another event type that is called a TIMESTAMP which can hold 64 bits of data in the theoretical case that two events happen 18 years apart. This code has not been implemented, but the name of this event exists, as well as the structure for it. The size of a TIMESTAMP is 16 bytes, where as a time extend is only 8 bytes. The macro used to calculate how many time extends can fit on a page used the TIMESTAMP size instead of the time extend size cutting the amount in half. The following test case can easily trigger the warning since we only need to have half the page filled with time extends to trigger the warning: # cd /sys/kernel/debug/tracing/ # echo function > current_tracer # echo 'common_pid < 0' > events/ftrace/function/filter # echo > trace # echo 1 > trace_marker # sleep 120 # cat trace Enabling the function tracer and then setting the filter to only trace functions where the process id is negative (no events), then clearing the trace buffer to ensure that we have nothing in the buffer, then write to trace_marker to add an event to the beginning of a page, sleep for 2 minutes (only 35 seconds is probably needed, but this guarantees the bug), and then finally reading the trace which will trigger the bug. This patch fixes the typo and prevents the false positive of that warning. Reported-by: Hans J. Koch <hjk@linutronix.de> Tested-by: Hans J.

This patch limit the vram allocation to visible vram until we have acceleration up and running.

2010-10-11fanotify: disable fanotify syscallsEric Paris2-2/+1
This patch disables the fanotify syscalls by just not building them and letting the cond_syscall() statements in kernel/sys_ni.c redirect them to sys_ni_syscall(). It was pointed out by Tvrtko Ursulin that the fanotify interface did not include an explicit prioritization between groups. This is necessary for fanotify to be usable for hierarchical storage management software, as they must get first access to the file, before inotify-like notifiers see the file. This feature can be added in an ABI compatible way in the next release (by using a number of bits in the flags field to carry the info) but it was suggested by Alan that maybe we should just hold off and do it in the next cycle, likely with an (new) explicit argument to the syscall. I don't like this approach best as I know people are already starting to use the current interface, but Alan is all wise and noone on list backed me up with just using what we have. I feel this is needlessly ripping the rug out from under people at the last minute, but if others think it needs to be a new argument it might be the best way forward. Three choices: Go with what we got (and implement the new feature next cycle). Add a new field right now (and implement the new feature next cycle). Wait till next cycle to release the ABI (and implement the new feature next cycle). This is number 3.

2010-10-11OSS: soundcard: locking bug in sound_ioctl()Dan Carpenter1-2/+2
We shouldn't return directly here because we're still holding the &soundcard_mutex. This bug goes all the way back to the start of git. It's strange that no one has complained about it as a runtime bug.

2010-10-11KVM: x86: Move TSC reset out of vmcb_initZachary Amsden1-1/+1
The VMCB is reset whenever we receive a startup IPI, so Linux is setting TSC back to zero happens very late in the boot process and destabilizing the TSC. Instead, just set TSC to zero once at VCPU creation time. Why the separate patch? So git-bisect is your friend.

2010-10-11KVM: x86: Fix SVM VMCB resetZachary Amsden1-1/+1
On reset, VMCB TSC should be set to zero. Instead, code was setting tsc_offset to zero, which passes through the underlying TSC. Signed-off-by: Zachary Amsden <zamsden@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2010-10-11x86, AMD, MCE thresholding: Fix the MCi_MISCj iteration orderBorislav Petkov1-6/+3
This fixes possible cases of not collecting valid error info in the MCE error thresholding groups on F10h hardware. The current code contains a subtle problem of checking only the Valid bit of MSR0000_0413 (which is MC4_MISC0 - DRAM thresholding group) in its first iteration and breaking out if the bit is cleared. But (!), this MSR contains an offset value, BlkPtr[31:24], which points to the remaining MSRs in this thresholding group which might contain valid information too. But if we bail out only after we checked the valid bit in the first MSR and not the block pointer too, we miss that other information. The thing is, MC4_MISC0[BlkPtr] is not predicated on MCi_STATUS[MiscV] or MC4_MISC0[Valid] and should be checked prior to iterating over the MCI_MISCj thresholding group, irrespective of the MC4_MISC0[Valid] setting.

2010-10-10net/fec: carrier off initially to avoid root mount failureOskar Schirmer1-0/+3
with hardware slow in negotiation, the system did freeze while trying to mount root on nfs at boot time. the link state has not been initialised so network stack tried to start transmission right away. this caused instant retries, as the driver solely stated business upon link down, rendering the system unusable. notify carrier off initially to prevent transmission until phylib will report link up.

2010-10-09kbuild: fix oldnoconfig to do the right thingKyle McMartin1-1/+1
Commit 861b4ea4 broke oldnoconfig when removed the oldnoconfig checks on if (input_mode == nonint_oldconfig || input_mode == oldnoconfig) { if (input_mode == nonint_oldconfig && sym->name && !sym_is_choice_value(sym)) { to avoid oldnoconfig chugging through the else stanza. Fix that to restore expected behaviour (which I've confirmed in the Fedora kernel build that the configs end up looking the same.)
