2010-07-12ocfs2: tighten up strlen() checkingDan Carpenter
This function is only called from one place and it's like this: dlm_register_domain(conn->cc_name, dlm_key, &fs_version); The "conn->cc_name" is 64 characters long. If strlen(conn->cc_name) were equal to O2NM_MAX_NAME_LEN (64) that would be a bug because strlen() doesn't count the NULL character. In fact, if you look how O2NM_MAX_NAME_LEN is used, it mostly describes 64 character buffers. The only exception is nd_name from struct o2nm_node. Anyway I looked into it and in this case the domain string comes from osb->uuid_str in ocfs2_setup_osb_uuid(). That's 32 characters and NULL which easily fits into O2NM_MAX_NAME_LEN. This patch doesn't change how the code works, but I think it makes the code a little cleaner. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>
2010-07-12ocfs2: Make xattr reflink work with new local alloc reservation.Tao Ma
The new reservation code in local alloc has add the limitation that the caller should handle the case that the local alloc doesn't give use enough contiguous clusters. It make the old xattr reflink code broken. So this patch udpate the xattr reflink code so that it can handle the case that local alloc give us one cluster at a time.

2010-07-12ocfs2: make xattr extension work with new local alloc reservation.Tao Ma
The old ocfs2_xattr_extent_allocation is too optimistic about the clusters we can get. So actually if the file system is too fragmented, ocfs2_add_clusters_in_btree will return us with EGAIN and we need to allocate clusters once again. So this patch change it to a while loop so that we can allocate clusters until we reach clusters_to_add.

2010-07-12ocfs2: No need to zero pages past i_size.Joel Becker
When ocfs2 fills a hole, it does so by allocating clusters. When a cluster is larger than the write, ocfs2 must zero the portions of the cluster outside of the write. If the clustersize is smaller than a pagecache page, this is handled by the normal pagecache mechanisms, but when the clustersize is larger than a page, ocfs2's write code will zero the pages adjacent to the write. This makes sure the entire cluster is zeroed correctly. Currently ocfs2 behaves exactly the same when writing past i_size. However, this means ocfs2 is writing zeroed pages for portions of a new cluster that are beyond i_size. The page writeback code isn't expecting this. It treats all pages past the one containing i_size as left behind due to a previous truncate operation. Thankfully, ocfs2 calculates the number of pages it will be working on up front. The rest of the write code merely honors the original calculation. We can simply trim the number of pages to only cover the actual file data.

2010-07-12ACPI: processor: fix processor_physically_present on UPAlex Chiang
The commit 5d554a7bb06 (ACPI: processor: add internal processor_physically_present()) is broken on uniprocessor (UP) configurations, as acpi_get_cpuid() will always return -1. We use the value of num_possible_cpus() to tell us whether we got an invalid cpuid from acpi_get_cpuid() in the SMP case, or if instead, we are UP, in which case num_possible_cpus() is #defined as 1. We use num_possible_cpus() instead of num_online_cpus() to protect ourselves against the scenario of CPU hotplug, and we've taken down all the CPUs except one.

2010-07-12ARM: Auto calculate ZRELADDR and provide option for exceptionsEric Miao
As long as the zImage is placed within the 128MB range from the start of memory, ZRELADDR (Address where the decompressed kernel will be placed, usually == PHYS_OFFSET + TEXT_OFFSET) can be determined at run-time by masking PC with 0xf80000000. Running through all the Makefile.boot, all those zreladdr-y addresses == 0x[0-f][08]00_0000 + TEXT_OFFSET can be determined at run-time. Option CONFIG_AUTO_ZRELADDR and CONFIG_ZRELADDR are introduced, CONFIG_ZRELADDR _must_ be explicitly specified if: - ((zreladdr-y - TEXT_OFFSET) & ~0xf8000000) != 0, which means masking PC with 0xf8000000 will result in an incorrect address. Currently this is only a problem on u300. - or the assumption of the zImage being loaded by the bootloader within the first 128MB of RAM is incorrect - or when ZBOOT_ROM is used, where the above assumption is usually wrong.

2010-07-11powerpc/fsl-booke: Fix address issue when using relocatable kernelsMatthew McClintock
When booting a relocatable kernel it needs to jump to the correct start address, which for BookE parts is usually unchanged regardless of the physical memory offset. Recent changes cause problems with how we calculate the start address, it was always adding the RMO into the start address which is incorrect. This patch only adds in the RMO offset if we are in the kexec code path, as it needs the RMO to work correctly. Instead of adding the RMO offset in in the common code path, we can just set r6 to the RMO offset in the kexec code path instead of to zero, and finally perform the masking in the common code path Signed-off-by: Matthew McClintock <msm@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

We essentially treat userspace as an entirely separate environment which isn't relevant to lockdep (lockdep doesn't monitor userspace.) We don't tell lockdep that IRQs will be enabled in that environment. Instead, when creating kernel threads (which is a rare event compared to entering/leaving userspace) we have to update the lockdep state. Do this by starting threads with IRQs disabled, and in the kthread helper, tell lockdep that IRQs are enabled, and enable them. This provides lockdep with a consistent view of the current IRQ state in kernel space. This also revert portions of 0d928b0b616d1c5c5fe76019a87cba171ca91633 which didn't fix the problem.

2010-07-09hwmon: (it87) Fix in7 on IT8720FJean Delvare
The IT8720F has no VIN7 pin, so VCCH should always be routed internally to VIN7 with an internal divider. Curiously, there still is a configuration bit to control this, which means it can be set incorrectly. And even more curiously, many boards out there are improperly configured, even though the IT8720F datasheet claims that the internal routing of VCCH to VIN7 is the default setting. So we force the internal routing in this case. It turns out that all boards with the wrong setting are from Gigabyte, so I suspect a BIOS bug. But it's easy enough to workaround in the driver, so let's do it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Jean-Marc Spaggiari <jean-marc@spaggiari.org> Cc: stable@kernel.org

2010-07-09ARM: 6204/1: Fixups for the RealView PB1176Linus Walleij
This is a number of basic fixes to the PB1176 that makes it tick properly: - Detect MMC insertion/removal even when PL061 GPIO is not compiled in. The register to read this status directly is removed on the PB1176. - Define the UART3 on the DevChip (where is actually is) and define the new UART4 serial port on the FPGA. - Also define the clocks for these two UARTs apropriately. - Remove the false notion that the PB1176 should have its CLCD on the ISSP, this is not the case, it is in the DevChip. - Remove the defintions and the previously commented-out PL081 DMAC. As confirmed by mail this was found to be broken on the PB1176 board and removed from the subsequent FPGA images.
