2009-03-31proc 2/2: remove struct proc_dir_entry::ownerAlexey Dobriyan
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

2009-02-20vmalloc: implement vm_area_register_early()Tejun Heo
Impact: allow multiple early vm areas There are places where kernel VM area needs to be allocated before vmalloc is initialized. This is done by allocating static vm_struct, initializing several fields and linking it to vmlist and later vmalloc initialization picking up these from vmlist. This is currently done manually and if there's more than one such areas, there's no defined way to arbitrate who gets which address. This patch implements vm_area_register_early(), which takes vm_area struct with flags and size initialized, assigns address to it and puts it on the vmlist. This way, multiple early vm areas can determine which addresses they should use. The only current user - alpha mm init - is converted to use it. Signed-off-by: Tejun Heo <tj@kernel.org>

2009-02-15net: new user space API for time stamping of incoming and outgoing packetsPatrick Ohly
User space can request hardware and/or software time stamping. Reporting of the result(s) via a new control message is enabled separately for each field in the message because some of the fields may require additional computation and thus cause overhead. User space can tell the different kinds of time stamps apart and choose what suits its needs. When a TX timestamp operation is requested, the TX skb will be cloned and the clone will be time stamped (in hardware or software) and added to the socket error queue of the skb, if the skb has a socket associated with it. The actual TX timestamp will reach userspace as a RX timestamp on the cloned packet. If timestamping is requested and no timestamping is done in the device driver (potentially this may use hardware timestamping), it will be done in software after the device's start_hard_xmit routine.

2009-01-29alpha: fix the BUG() macroIvan Kokshaysky
The commit "alpha: teach the compiler that BUG doesn't return" (ed6b9b97f42c091630335bfb71a2931e6f86388b) moved the asm code into inline function which takes __FILE__ and __LINE__ as arguments. This violates asm constrains there ("i" - an immediate operand with constant value), so that compile may result in warning or error, depending on compiler version. Just adding an infinite loop to the BUG() is sufficient.

2009-01-15alpha: fix RTC on marvelIvan Kokshaysky
Unlike other alphas, marvel doesn't have real PC-style CMOS clock hardware - RTC accesses are emulated via PAL calls. Unfortunately, for unknown reason these calls work only on CPU #0. So current implementation for arbitrary CPU makes CMOS_READ/WRITE to be executed on CPU #0 via IPI. However, for obvious reason this doesn't work with standard get/set_rtc_time() functions, where a bunch of CMOS accesses is done with disabled interrupts. Solved by making the IPI calls for entire get/set_rtc_time() functions, not for individual CMOS accesses. Which is also a lot more effective performance-wise. The patch is largely based on the code from Jay Estabrook. My changes: - tweak asm-generic/rtc.h by adding a couple of #defines to avoid a massive code duplication in arch/alpha/include/asm/rtc.h; - sys_marvel.c: fix get/set_rtc_time() return values (Jay's FIXMEs). NOTE: this fixes *only* LIB_RTC drivers. Legacy (CONFIG_RTC) driver wont't work on marvel. Actually I think that we should just disable CONFIG_RTC on alpha (maybe in 2.6.30?), like most other arches - AFAIK, all modern distributions use LIB_RTC anyway.

2009-01-15alpha: nautilus - fix hang on bootIvan Kokshaysky
Recently introduced generic pci_common_swizzle() relies on bus->self being NULL for the root PCI bus. But on nautilus bus->self points to the host bridge device, which is necessary as we do a root bus sizing on this system. As a result, pci_common_swizzle() loops infinitely. This worked until 2.6.29-rc1 because the alpha-specific swizzle routine checked for bus->parent == NULL (instead of bus->self). Fixed by clearing bus->self after bus sizing is done.

2009-01-15alpha: nautilus - fix compile failure with gcc-4.3Ivan Kokshaysky
init_srm_irq() deals with irq's #16 and above, but size of irq_desc array on nautilus and some other system types is 16. So gcc-4.3 complains that "array subscript is above array bounds", even though this function is never called on those systems. This adds a check for NR_IRQS <= 16, which effectively optimizes init_srm_irq() code away on problematic platforms. Thanks to Daniel Drake <dsd@gentoo.org> for detailed analysis of the problem.
