2009-03-24dma-debug: make memory range checks more consistentJoerg Roedel
Impact: extend on-kernel-stack DMA debug checks to all !highmem pages We only checked dma_map_single() - extend it to dma_map_page() and dma_map_sg() as well. Also, fix dma_map_single() corner case bug: make sure we dont stack-check highmem (not mapped) pages.

2009-03-17Avoid 64-bit "switch()" statements on 32-bit architecturesLinus Torvalds
Commit ee6f779b9e0851e2f7da292a9f58e0095edf615a ("filp->f_pos not correctly updated in proc_task_readdir") changed the proc code to use filp->f_pos directly, rather than through a temporary variable. In the process, that caused the operations to be done on the full 64 bits, even though the offset is never that big. That's all fine and dandy per se, but for some unfathomable reason gcc generates absolutely horrid code when using 64-bit values in switch() statements. To the point of actually calling out to gcc helper functions like __cmpdi2 rather than just doing the trivial comparisons directly the way gcc does for normal compares. At which point we get link failures, because we really don't want to support that kind of crazy code. Fix this by just casting the f_pos value to "unsigned long", which is plenty big enough for /proc, and avoids the gcc code generation issue.

Don't boost at the addresses which are listed on exception tables, because major page fault will occur on those addresses.

2009-03-17Fast TSC calibration: calculate proper frequency error boundsLinus Torvalds
In order for ntpd to correctly synchronize the clocks, the frequency of the system clock must not be off by more than 500 ppm (or, put another way, 1:2000), or ntpd will end up giving up on trying to synchronize properly, and ends up reseting the clock in jumps instead. The fast TSC PIT calibration sometimes failed this test - it was assuming that the PIT reads always took about one microsecond each (2us for the two reads to get a 16-bit timer), and that calibrating TSC to the PIT over 15ms should thus be sufficient to get much closer than 500ppm (max 2us error on both sides giving 4us over 15ms: a 270 ppm error value). However, that assumption does not always hold: apparently some hardware is either very much slower at reading the PIT registers, or there was other noise causing at least one machine to get 700+ ppm errors. So instead of using a fixed 15ms timing loop, this changes the fast PIT calibration to read the TSC delta over the individual PIT timer reads, and use the result to calculate the error bars on the PIT read timing properly. We then successfully calibrate the TSC only if the maximum error bars fall below 500ppm. In the process, we also relax the timing to allow up to 25ms for the calibration, although it can happen much faster depending on hardware.

2009-03-17Fix potential fast PIT TSC calibration startup glitchLinus Torvalds
During bootup, when we reprogram the PIT (programmable interval timer) to start counting down from 0xffff in order to use it for the fast TSC calibration, we should also make sure to delay a bit afterwards to allow the PIT hardware to actually start counting with the new value. That will happens at the next CLK pulse (1.193182 MHz), so the easiest way to do that is to just wait at least one microsecond after programming the new PIT counter value. We do that by just reading the counter value back once - which will take about 2us on PC hardware.

This adds a function to dump the DMA mappings that the debugging code is aware of -- either for a single device, or for _all_ devices. This can be useful for debugging -- sticking a call to it in the DMA page fault handler, for example, to see if the faulting address _should_ be mapped or not, and hence work out whether it's IOMMU bugs we're seeing, or driver bugs.

2009-03-16dm crypt: fix kcryptd_async_done parameterHuang Ying
In the async encryption-complete function (kcryptd_async_done), the crypto_async_request passed in may be different from the one passed to crypto_ablkcipher_encrypt/decrypt. Only crypto_async_request->data is guaranteed to be same as the one passed in. The current kcryptd_async_done uses the passed-in crypto_async_request directly which may cause the AES-NI-based AES algorithm implementation to panic. This patch fixes this bug by only using crypto_async_request->data, which points to dm_crypt_request, the crypto_async_request passed in. The original data (convert_context) is gotten from dm_crypt_request.

2009-03-16filp->f_pos not correctly updated in proc_task_readdirZhang Le
filp->f_pos only get updated at the end of the function. Thus d_off of those dirents who are in the middle will be 0, and this will cause a problem in glibc's readdir implementation, specifically endless loop. Because when overflow occurs, f_pos will be set to next dirent to read, however it will be 0, unless the next one is the last one. So it will start over again and again. There is a sample program in man 2 gendents.

Looking at the source, there seems to be a missing * to match my DMI string.

2009-03-14igb: remove ASPM L0s workaroundAlexander Duyck
The L0s workaround should be moved into a pci quirk and so it is not necessary in the driver. This update removes the L0s workaround from the igb driver. This was the second half of the PCI quirk patch that Matthew Wilcox did not pick up when he picked up the quirk patch.

* 'for-linus' of git://git.kernel.dk/linux-2.6-block: Fix Xilinx SystemACE driver to handle empty CF slot block: fix memory leak in bio_clone() block: Add gfp_mask parameter to bio_integrity_clone()
2009-03-14Fix Xilinx SystemACE driver to handle empty CF slotGrant Likely
The SystemACE driver does not handle an empty CF slot gracefully. An empty CF slot ends up hanging the system. This patch adds a check for the CF state and stops trying to process requests if the slot is empty.

2009-03-14block: fix memory leak in bio_clone()Li Zefan
If bio_integrity_clone() fails, bio_clone() returns NULL without freeing the newly allocated bio. Signed-off-by: Li Zefan <lizf@cn.fujitsu.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2009-03-14block: Add gfp_mask parameter to bio_integrity_clone()un'ichi Nomura
Stricter gfp_mask might be required for clone allocation. For example, request-based dm may clone bio in interrupt context so it has to use GFP_ATOMIC.
