I had an issue on ia64 where I got a bug in kernel/workqueue because kzalloc returned a NULL pointer due to the task structure getting too big for the slab allocator. Usually these cases are caught by the kmalloc macro in include/linux/slab.h. Compilation will fail if a too big value is passed to kmalloc. However, kzalloc uses __kmalloc which has no check for that. This patch makes __kmalloc bug if a too large entity is requested. Signed-off-by:

The PowerMac mesh SCSI driver had some missing error handling which would trigger warnings due to lack of handling of return value from scsi_add_host. This fixes it. Signed-off-by:

The SMU is the "system controller" chip used by Apple recent G5 machines including the iMac G5. It drives things like fans, i2c busses, real time clock, etc... The current kernel contains a very crude driver that doesn't do much more than reading the real time clock synchronously. This is a completely rewritten driver that provides interrupt based command queuing, a userland interface, and an i2c/smbus driver for accessing the devices hanging off the SMU i2c busses like temperature sensors. This driver is a basic block for upcoming work on thermal control for those machines, among others. Signed-off-by:

Anton Blanchard authored
The recent iommu fix broke booting on some POWER4 and POWER5 LPAR boxes. It looks like we have been calling the non LPAR iommu_dev_setup on LPAR machines for a while. The recent iommu fix caused that code path to fail. It looks like we just need to hook up the devices iommu_table to the parents one, so do that instead of calling iommu_dev_setup_pSeries and crossing the streams. Signed-off-by:

The numa slab allocator may allocate pages from foreign nodes onto the lists for a particular node if a node runs out of memory. Inspecting the slab->nodeid field will not reflect that the page is now in use for the slabs of another node. This patch fixes that issue by adding a node field to free_block so that the caller can indicate which node currently uses a slab. Also removes the check for the current node from kmalloc_cache_node since the process may shift later to another node which may lead to an allocation on another node than intended. Signed-off-by:

The address passed to io_remap_pfn_range() in hpet_mmap() does not need to be converted using __pa(): it is already a physical address. This bug was found and the patch suggested by Clay Harris. I introduced this particular bug when making io_remap_pfn_range changes a few months ago. In fact mmap()ing /dev/hpet has *never* previously worked: before my changes __pa() was being executed on an ioremap()ed virtual address, which is also invalid. Signed-off-by:

If error occurs while in v9fs_get_sb after it calles sget, the dentry object of the root and its inode may be freed twice -- once while handling the error in v9fs_get_sb, and second time when v9fs_get_sb calles deactivate_super (which in turn calls v9fs_kill_super) The patch removes the unnecessary code that frees the root dentry and its inode.

v9fs_vfs_readlink allocates space for the link using __getname and errorneously uses strlen on the newly allocated buffer to check if the buffer passed by the user is bigger than the one returned by __getname. The patch replaces the strlen usage to PATH_MAX, which is the actual size of the buffers returned by __getname. Signed-off-by:

When a new session is created it uses a template object of the specified transport type to instantiate its own copy. The code for the making a copy of the template object was lost, and the object itself is attached to the v9fs session. This leads to many sessions using the same transport instead of having their own copy. The patch puts back the code that makes a copy of the template object. Signed-off-by:

buf_check_size function checks if the conv buffer has enough space for the performed operation, but it doesn't return the result back to the calling function, only logs an error in the log. The report-back-error functionality was lost when buf_check_size was converted from macro to inline function. The return in the macro used to exit from the functions that include it, after the conversion it just exits from the inline function itself. The patch makes buf_check_size to return flag and all functions that use it check if they should perform the operation, or exit. Signed-off-by:

In the lead up to 2.6.13 I fixed a large number of reboot problems by making the calling conventions consistent. Despite checking and double checking my work it appears I missed an obvious one. The S4 suspend code for PM_DISK_PLATFORM was also calling device_shutdown without setting system_state, and was not calling the appropriate reboot_notifier. This patch fixes the bug by replacing the call of device_suspend with kernel_poweroff_prepare. Various forms of this failure have been fixed and tracked for a while. Thanks for tracking this down go to: Alexey Starikovskiy, Meelis Roos <mroos@linux.ee>, Nigel Cunningham <ncunningham@cyclades.com>, Pierre Ossman <drzeus-list@drzeus.cx> History of this bug is at: http://bugme.osdl.org/show_bug.cgi?id=4320Signed-off-by:

In the lead up to 2.6.13 I fixed a large number of reboot problems by making the calling conventions consistent. Despite checking and double checking my work it appears I missed an obvious one. This first patch simply refactors the reboot routines so all of the preparation for various kinds of reboots are in their own functions. Making it very hard to get the various kinds of reboot out of sync. Signed-off-by:

Addresses some small bugs in the pegasus ethernet-over-USB driver. Specifically, malformed long packets from the adapter could cause a kernel panic; the interrupt interval calculation was inappropriate for high-speed devices; the return code from read_mii_word was tested incorrectly; and failure to unlink outstanding URBs before freeing them could lead to kernel panics when unloading the driver.

Three minor sl811-hcd fixes: - Elminate memory leak on one (rare) disable/shutdown path. - For periodic transfers that don't need to be scheduled, update urb->start_frame to represent the transfer phase correctly. - Report the (single) port as removable, by default. Since no drivers yet use start_frame or that part of the hub descriptor, only that leak is likely to ever matter. Signed-off-by:
