2007-02-20[PATCH] remove modpost false warnings on ARMDavid Brownell
This patch stops "modpost" from issuing erroneous modpost warnings on ARM builds, which it's been doing since since maybe last summer. A canonical example would be driver method table entries: WARNING: <path> - Section mismatch: reference to .exit.text:<name>_remove from .data after '$d' (at offset 0x4) That "$d" symbol is generated by tools conformant with ARM ABI specs; in this case it's a symbol **in the middle of** a "<name>_driver" struct. The erroneous warnings appear to be issued because "modpost" whitelists references from "<name>_driver" data into init and exit sections ... but doesn't know should also include those "$d" mapping symbols, which are not otherwise associated with "<name>_driver" symbols. This patch prevents the modpost symbol lookup code from ever returning those mapping symbols, so it will return a whitelisted symbol instead. Then things work as expected. Now to revert various code-bloating "fixes" that got merged because of this modpost bug....

2007-02-20[PATCH] at91_rtc updatesDavid Brownell
Various bug fixes to the at91rm9200 RTC: - alarm: setalarm() should pay attention to the "enabled" flag - init: cleaner handling of the wakeup flags, which cpu init should really have set up. Doing it here is just a workaround. - linkage: since the at91_rtc driver probe() routine is in the init section, it should use platform_driver_probe() instead of leaving that pointer around in the driver struct after init section removal. - linkage: likewise, remove() belongs in the exit section. Among other things, the init and alarm changes ensure that this driver handles the new sysfs "wakealarm" attribute properly.

2007-02-20[PATCH] rtc-sa1100 rtc_wklarm.enabled bugfixesDavid Brownell
Some rtc-sa1100 bugfixes: - The read_alarm() method reports the rtc_wkalrm.enabled field properly. This patch is already in the handhelds.org tree. - And the set_alarm() method now handles that flag correctly, rather than making mismatched {en,dis}able_irq_wake() calls, which trigger runtime warning messages. (Those calls are best made in suspend/resume methods.) Note that while this SA1100/PXA RTC is fully capable of waking those ARM processors from sleep states, that mechanism isn't properly supported on either processor family, or in this driver. Some boards have board-specific PM glue providing partial workarounds for the weak generic PM support.

2007-02-20[PATCH] autofs4: check for directory re-create in lookupIan Kent
This problem was identified and fixed some time ago by Jeff Moyer but it fell through the cracks somehow. It is possible that a user space application could remove and re-create a directory during a request. To avoid returning a failure from lookup incorrectly when our current dentry is unhashed we need to check if another positive, hashed dentry matching this one exists and if so return it instead of a fail.

2007-02-20[PATCH] autofs4: fix another race between mount and expireIan Kent
Jeff Moyer has identified a race between mount and expire. What happens is that during an expire the situation can arise that a directory is removed and another lookup is done before the expire issues a completion status to the kernel module. In this case, since the the lookup gets a new dentry, it doesn't know that there is an expire in progress and when it posts its mount request, matches the existing expire request and waits for its completion. ENOENT is then returned to user space from lookup (as the dentry passed in is now unhashed) without having performed the mount request. The solution used here is to keep track of dentrys in this unhashed state and reuse them, if possible, in order to preserve the flags. Additionally, this infrastructure will provide the framework for the reintroduction of caching of mount fails removed earlier in development.

2007-02-20[PATCH] fs: fix nobh data leakNick Piggin
nobh_prepare_write leaks data similarly to how simple_prepare_write did. Fix by not marking the page uptodate until nobh_commit_write time. Again, this could break weird use-cases, but none appear to exist in the tree. We can safely remove the set_page_dirty, because as the comment says, nobh_commit_write does set_page_dirty. If a filesystem wants to allocate backing store for a page dirtied via mmap, page_mkwrite is the suggested approach.
