* at24: Use timeout also for readWolfram Sang2009-11-26
| | | | | | | | | | | | | | | Writes may take some time on EEPROMs, so for consecutive writes, we already have a loop waiting for the EEPROM to become ready. Use such a loop for reads, too, in case somebody wants to immediately read after a write. Detailed bug report and test case can be found here: http://article.gmane.org/gmane.linux.drivers.i2c/4660 Reported-by: Aleksandar Ivanov <ivanov.aleks@gmail.com> Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Tested-by: Aleksandar Ivanov <ivanov.aleks@gmail.com> Cc: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c: Fix userspace_device list corruptionJean Delvare2009-11-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix userspace_device list corruption. The corruption was caused by clients not being removed when adapters with such clients were themselves removed. Something like the following would trigger it (assuming i2c-stub gets adapter number 3): # modprobe i2c-stub chip_addr=0x50 # echo 24c08 0x50 > /sys/bus/i2c/devices/i2c-3/new_device # rmmod i2c-stub # modprobe i2c-stub chip_addr=0x50 # echo 24c08 0x50 > /sys/bus/i2c/devices/i2c-3/new_device For the records, the stack trace in the kernel logs look like this: kernel: WARNING: at lib/list_debug.c:30 __list_add+0x8b/0x90() kernel: Hardware name: (...) kernel: list_add corruption. prev->next should be next (c137fc84), but was (null).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the f_fsid of struct kstatfs returned from ocfs2_statfs() is undefined (vfs layer fills in 0 as default). Since in some conditions, f_fsid value might be used in a (f_fsid, ino) pair to uniquely identify a file, ocfs2 should return a unique defined f_fsid value from ocfs2_statfs(). Because uuid_str is the same on big or litlle endian machine, it's endian consistent to use osb->uuid_str to generate f_fsid value.

This causes the readdir() function to fail to return a fileid/inode number, which again exposed a bug in the NFS readdir code that causes spurious ENOENT errors to appear in applications (see http://bugzilla.kernel.org/show_bug.cgi?id=14541). The immediate band aid is to revert the incorrect bitmap change, but more long term, we should change the NFS readdir code to cope with the fact that NFSv4 servers are not required to support fileids/inode numbers.

* | | Fix handling of the HP/Acer 'DMAR at zero' BIOS error for machines with ↵David Woodhouse2009-11-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <4GiB RAM. Commit 86cf898e1d0fca245173980e3897580db38569a8 ("intel-iommu: Check for 'DMAR at zero' BIOS error earlier.") was supposed to work by pretending not to detect an IOMMU if it was actually being reported by the BIOS at physical address zero. However, the intel_iommu_init() function is called unconditionally, as are the corresponding functions for other IOMMU hardware. So the patch only worked if you have RAM above the 4GiB boundary. It caused swiotlb to be initialised when no IOMMU was detected during early boot, and thus the later IOMMU init would refuse to run. But if you have less RAM than that, swiotlb wouldn't get set up and the IOMMU _would_ still end up being initialised, even though we never claimed to detect it. This patch also sets the dmar_disabled flag when the error is detected during the initial detection phase -- so that the later call to intel_iommu_init() will return without doing anything, regardless of whether swiotlb is used or not.

Before applying the patch I compiled and booted the tree to see if the panic was still there -- to my surprise it was not. This is because of the conversion of cpufreq_cpu_governor to a char[]. While the panic is kaput, the problem of stale data continues and my patch is still valid. It is possible to end up with the wrong governor after hotplug events because CPUFREQ_DEFAULT_GOVERNOR is statically linked to a default, while the cpu siblings may have had a different governor assigned by a user. ie) the patch is still needed in order to keep the governors assigned properly when hotplugging devices Signed-off-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Dave Jones <davej@redhat.com>
