2011-07-25hwmon: (lm78) Become the maintainerJean Delvare
Declare myself the maintainer of the lm78 driver. I still have a running system with one of these chips. Also count myself as a co-author of the driver. With 34 commits over 6 years, it seems fair. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2011-07-25hwmon: (lm78) Make ISA interface depend on CONFIG_ISAJean Delvare
We should only include support for the ISA interface of the LM78/LM79 if CONFIG_ISA is set. Not only this makes the driver somewhat smaller on most architectures, but this also avoids poking at random I/O ports on these architectures. This is very similiar to what was done for the w83781d driver in October 2008. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Dean Nelson <dnelson@redhat.com>
2011-07-25hwmon: (lm78) Avoid forward declarationsJean Delvare

2011-07-25hwmon: New driver sch5636Hans de Goede
This patch adds a new driver for SMSC SCH5636 Super I/O chips. The chips include an embedded microcontroller for hardware monitoring solutions, allowing motherboard manufacturers to create their own custom hwmon solution based upon the SCH5636. Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636 based hwmon solution. The sch5636 driver runs a sanity check on loading to ensure it is dealing with a Fujitsu Theseus and not with another custom SCH5636 based hwmon solution.

2011-07-25NFSv4: Don't use the delegation->inode in nfs_mark_return_delegation()Trond Myklebust
nfs_mark_return_delegation() is usually called without any locking, and so it is not safe to dereference delegation->inode. Since the inode is only used to discover the nfs_client anyway, it makes more sense to have the callers pass a valid pointer to the nfs_server as a parameter.

2011-07-25nfs: don't use d_move in nfs_async_rename_doneJeff Layton
If the task that initiated the sillyrename ends up being killed by a fatal signal, then it will eventually return back to userspace and end up releasing the i_mutex. d_move however needs to be done while holding the i_mutex. Instead of using d_move here, just unhash the old and new dentries to prevent them from being found by lookups. With this change though, the dentries are now incorrect post-rename and do not reflect the actual name of the file on the server. I'm proceeding under the assumption that since they are unhashed that this isn't really a problem. In order for the sillydelete to still work though, the dname must be copied earlier when setting up the sillydelete info, and the name must be recopied if the sillydelete info has to be moved to a new dentry.

2011-07-25vfs: move ACL cache lookup into generic codeLinus Torvalds
This moves logic for checking the cached ACL values from low-level filesystems into generic code. The end result is a streamlined ACL check that doesn't need to load the inode->i_op->check_acl pointer at all for the common cached case. The filesystems also don't need to check for a non-blocking RCU walk case in their acl_check() functions, because that is all handled at a VFS layer.

2011-07-25CIFS: Fix oops while mounting with prefixpathPavel Shilovsky
commit fec11dd9a0109fe52fd631e5c510778d6cbff6cc caused a regression when we have already mounted //server/share/a and want to mount //server/share/a/b. The problem is that lookup_one_len calls __lookup_hash with nd pointer as NULL. Then __lookup_hash calls do_revalidate in the case when dentry exists and we end up with NULL pointer deference in cifs_d_revalidate: if (nd->flags & LOOKUP_RCU) return -ECHILD; Fix this by checking nd for NULL.

2011-07-25MIPS: Add SYNC after cacheflushKevin Cernekee
On processors with deep write buffers, it is likely that many cycles will pass between a CACHE instruction and the time the data actually gets written out to DRAM. Add a SYNC instruction to ensure that the buffers get emptied before the flush functions return. Actual problem seen in the wild: 1) dma_alloc_coherent() allocates cached memory 2) memset() is called to clear the new pages 3) dma_cache_wback_inv() is called to flush the zero data out to memory 4) dma_alloc_coherent() returns an uncached (kseg1) pointer to the freshly allocated pages 5) Caller writes data through the kseg1 pointer 6) Buffered writeback data finally gets flushed out to DRAM 7) Part of caller's data is inexplicably zeroed out This patch adds SYNC between steps 3 and 4, which fixed the problem.

2011-07-25MIPS: pfn_valid() is broken on low memory HIGHMEM systemsKevin Cernekee
pfn_valid() compares the PFN to max_mapnr: __pfn >= min_low_pfn && __pfn < max_mapnr; On HIGHMEM kernels, highend_pfn is used to set the value of max_mapnr. Unfortunately, highend_pfn is left at zero if the system does not actually have enough RAM to reach into the HIGHMEM range. This causes pfn_valid() to always return false, and when debug checks are enabled the kernel will fail catastrophically: Memory: 22432k/32768k available (2249k kernel code, 10336k reserved, 653k data, 1352k init, 0k highmem) NR_IRQS:128 kfree_debugcheck: out of range ptr 81c02900h.

2011-07-25MIPS: topdown mmap supportJian Peng
This patch introduced topdown mmap support in user process address space allocation policy. Recently, we ran some large applications that use mmap heavily and lead to OOM due to inflexible mmap allocation policy on MIPS32. Since most other major archs supported it for years, it is reasonable to follow the trend and reduce the pain of porting applications. Due to cache aliasing concern, arch_get_unmapped_area_topdown() and other helper functions are implemented in arch/mips/kernel/syscall.c.

2011-07-25i2c: Allow i2c_add_numbered_adapter() to assign a bus idGrant Likely
Currently, if an i2c bus driver supports both static and dynamic bus ids, it needs to choose between calling i2c_add_numbered_adapter() and i2c_add_adapter(). This patch makes i2c_add_numbered_adapter() redirect to i2c_add_adapter() if the requested bus id is -1.
