2006-08-26[PATCH] unusual_devs update for UCR-61S2BAlan Stern
The existing unusual_devs entry for the UCR-61S2B appears to have too wide a revision range. It matches at least one device that doesn't respond to the initialization sequence. Perhaps the sequence needs to be updated, or perhaps something else can be done. For now, this patch (as764) restricts the range to include only the revision mentioned in the original comment. This resolves (for now!) Bugzilla entry #6950. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-08-26[PATCH] CPCI hotplug: fix resource assignmentScott Murray
Here is a patch against the CPCI hotplug core to fix up PCI resource assignment such that things will actually work when a hot inserted device is enabled. I mentioned this patch to you way back in April at ELC, but am only now out from under things enough to clean it up and submit it. I've basically cribbed the corresponding code from shpchp_pci.c, so there are no big surprises. If it's still possible, I wouldn't mind this going into 2.6.18, but it wouldn't be the end of the world if it went into 2.6.19.

2006-08-26[PATCH] PCI: use PCBIOS as last fallbackDaniel Ritz
there was a change in 2.6.17 which affected the order in which the PCI access methods are probed. this gives regressions on some machines with broken BIOS. the problem is that PCBIOS sometimes reports last bus wrong, leaving cardbus non-funcational. previously those system worked fine with direct access. The patch changes the PCI init code to have PCBIOS as last fallback, yet the PCBIOS code still has to run first to set pcibios_last_bus to the value reported by the BIOS. this is needed in case legacy PCI probing (arch/i386/pci/legacy.c) is used to detect peer busses. using direct access if available fixes the cardbus problems.

2006-08-26[PATCH] hwmon: abituguru timeout fixesHans de Goede
This patch contains 2 sets of fixes for the abituguru: 1) Much improved timeout handling, drasticly reducing the amount of timeout errors on some motherboards 2) Fix the exit paths in the bank1 sensor type detect code to always restore the original settings even on an error. Without this our special test settings could remain seriously confusing the system BIOS's setup menu. Both are very much related and are must haves, to avoid messing up the uguru CMOS settings. Detailed changes: - Much improved timeout / wait for status handling. Many thanks to Sunil Kumar, for all his testing, ideas and patches! The code now first busy waits, polling the uguru for the expected status as this usually succeeds pretty quickly (within 90 reads). To avoid unnecessary CPU burn in timeout conditions, the amount of busy waiting has been halved from previous versions (120 tries instead of 250). This is not a problem, because this version goes to sleep after 120 attemps for 1 jiffy and then tries again, it does this sleep and try again 5 times before finally giving up. This (almost?) completly removes the timeout errors some people have seen regulary. Apparently some older uguru versions sometimes are distracted for a (relatively) long time. This solves this. - These timeout errors not only occur in the sending address part of reading the uguru but also in the wait for read state, so errors in this state are now handled as retryable just like send address state errors and are only logged and reported to userspace if 3 executive tries fail. - Fix a very nasty bug in the bank1 sensor type detection code, where it would not restore the original settings in any of the error paths! - Since not successfully restoring the original settings can seriously confuse the system BIOS (hang when entering the relevant setup menu), we now try restoring them 3 times before giving up.

2006-08-26[PATCH] i2c: tps65010 build fixesDavid Brownell
The tps65010.c driver in the main tree never got updated with build fixes since the last batch of I2C driver changes; and the genirq trigger flags were updated wierdly too. This also includes a minor tweak to reduce the frequency used to poll for unplug-the-AC-power on the TPS chips that don't provide relevant IRQs. It _would_ be nice to sense whether there's even a battery, but that'd normally be an HDQ/1-wire interface to a smart battery, and such APIs aren't standardized.

2006-08-26[SCSI] fix scsi_send_eh_cmnd regressionMike Christie
The callers of scsi_send_eh_cmnd are setting the cmnd buffer, and then scsi_send_eh_cmnd is copying that updated buffer to the old_cmnd variable. Then after the command runs, we end up copying that old_cmnd var which has the new cmnd to the scsi command buffer. When this command gets recent, all types of fun things happen like getting TUR or START_STOP commands with data and scatterlists. This patch made against scsi-rc-fixes, has the callers of scsi_send_eh_cmnd pass in the command so scsi_send_eh_cmnd can do the right thing. This should go into 2.6.18 since this fixes a regression added when we removed some of the scsi_cmnd fields and replaced them with local variables.

If the driver never performed a successful PLOGI/PRLI, the port-type would never be assigned, and the relogin logic would silently drop the request (and thus the port would not be recognized and registered).

2006-08-24VFS: Fix access("file", X_OK) in the presence of ACLsTrond Myklebust
Currently, the access() call will return incorrect information on NFS if there exists an ACL that grants execute access to the user on a regular file. The reason the information is incorrect is that the VFS overrides this execute access in open_exec() by checking (inode->i_mode & 0111).

2006-08-24NFS: Check lengths more thoroughly in NFS4 readdir XDR decodeDavid Howells
Check the bounds of length specifiers more thoroughly in the XDR decoding of NFS4 readdir reply data. Currently, if the server returns a bitmap or attr length that causes the current decode point pointer to wrap, this could go undetected (consider a small "negative" length on a 32-bit machine). Also add a check into the main XDR decode handler to make sure that the amount of data is a multiple of four bytes (as specified by RFC-1014). This makes sure that we can do u32* pointer subtraction in the NFS client without risking an undefined result (the result is undefined if the pointers are not correctly aligned with respect to one another).

2006-08-24VFS: add lookup hint for network file systemsASANO Masahiro
I'm trying to speeding up mkdir(2) for network file systems. A typical mkdir(2) calls two inode_operations: lookup and mkdir. The lookup operation would fail with ENOENT in common case. I think it is unnecessary because the subsequent mkdir operation can check it. In case of creat(2), lookup operation is called with the LOOKUP_CREATE flag, so individual filesystem can omit real lookup. e.g. nfs_lookup(). Here is a sample patch which uses LOOKUP_CREATE and O_EXCL on mkdir, symlink and mknod. This uses the gadget for creat(2).

The slabs are assumed to be aligned on a HUGEPTE_TABLE_SIZE boundary. The free path makes use of this assumption and uses the lowest nibble to pass around an index into an array of kmem_cache pointers. With slab debugging turned on, the slab is still aligned, but the "working" object pointer is not. This would break the assumption above that a full nibble is available for the PGF_CACHENUM_MASK. The following patch reduces PGF_CACHENUM_MASK to cover only the two least significant bits, which is enough to cover the current number of 4 pgtable cache types.
