2014-05-13of: kill off of_can_translate_addressRob Herring1-1/+0
of_can_translate_address only checks some conditions for address translation, but does not check other conditions like having range properties. The checks it does do are redundant with __of_address_translate. The only difference is printing a message or not. Since we only have a single caller that does the full translation anyway, just remove of_can_translate_address and quiet the error message.

2014-05-13rcutorture: Add forward-progress checking for writerPaul E. McKenney1-0/+19
The rcutorture output currently does not distinguish between stalls in the RCU implementation and stalls in the rcu_torture_writer() kthreads. This commit therefore adds some diagnostics to help distinguish between these two conditions, at least for the non-SRCU implementations.

Convert all cftype->write_string() users to the new cftype->write() which maps directly to kernfs write operation and has full access to kernfs and cgroup contexts. The conversions are mostly mechanical. * @css and @cft are accessed using of_css() and of_cft() accessors respectively instead of being specified as arguments. * Should return @nbytes on success instead of 0. * @buf is not trimmed automatically. Trim if necessary. Note that blkcg and netprio don't need this as the parsers already handle whitespaces. cftype->write_string() has no user left after the conversions and removed. While at it, remove unnecessary local variable @p in cgroup_subtree_control_write() and stale comment about CGROUP_LOCAL_BUFFER_SIZE in cgroup_freezer.c. This patch doesn't introduce any visible behavior changes. v2: netprio was missing from conversion. Converted.

2014-05-13cgroup: implement cftype->write()Tejun Heo1-4/+23
During the recent conversion to kernfs, cftype's seq_file operations are updated so that they are directly mapped to kernfs operations and thus can fully access the associated kernfs and cgroup contexts; however, write path hasn't seen similar updates and none of the existing write operations has access to, for example, the associated kernfs_open_file. Let's introduce a new operation cftype->write() which maps directly to the kernfs write operation and has access to all the arguments and contexts. This will replace ->write_string() and ->trigger() and ease manipulation of kernfs active protection from cgroup file operations. Two accessors - of_cft() and of_css() - are introduced to enable accessing the associated cgroup context from cftype->write() which only takes kernfs_open_file for the context information. The accessors for seq_file operations - seq_cft() and seq_css() - are rewritten to wrap the of_ accessors. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Li Zefan <lizefan@huawei.com>
2014-05-13cgroup: rename css_tryget*() to css_tryget_online*()Tejun Heo1-7/+7
Unlike the more usual refcnting, what css_tryget() provides is the distinction between online and offline csses instead of protection against upping a refcnt which already reached zero. cgroup is planning to provide actual tryget which fails if the refcnt already reached zero. Let's rename the existing trygets so that they clearly indicate that they're onliness. I thought about keeping the existing names as-are and introducing new names for the planned actual tryget; however, given that each controller participates in the synchronization of the online state, it seems worthwhile to make it explicit that these functions are about on/offline state. Rename css_tryget() to css_tryget_online() and css_tryget_from_dir() to css_tryget_online_from_dir(). This is pure rename. v2: cgroup_freezer grew new usages of css_tryget(). Update accordingly.

2014-05-13cgroup: introduce task_css_is_root()Tejun Heo1-0/+15
Determining the css of a task usually requires RCU read lock as that's the only thing which keeps the returned css accessible till its reference is acquired; however, testing whether a task belongs to the root can be performed without dereferencing the returned css by comparing the returned pointer against the root one in init_css_set[] which never changes. Implement task_css_is_root() which can be invoked in any context. This will be used by the scheduled cgroup_freezer change. v2: cgroup no longer supports modular controllers.

2014-05-13kernfs, sysfs, cgroup: restrict extra perm check on open to sysfsTejun Heo1-1/+18
The kernfs open method - kernfs_fop_open() - inherited extra permission checks from sysfs. While the vfs layer allows ignoring the read/write permissions checks if the issuer has CAP_DAC_OVERRIDE, sysfs explicitly denied open regardless of the cap if the file doesn't have any of the UGO perms of the requested access or doesn't implement the requested operation. It can be debated whether this was a good idea or not but the behavior is too subtle and dangerous to change at this point. After cgroup got converted to kernfs, this extra perm check also got applied to cgroup breaking libcgroup which opens write-only files with O_RDWR as root. This patch gates the extra open permission check with a new flag KERNFS_ROOT_EXTRA_OPEN_PERM_CHECK and enables it for sysfs. For sysfs, nothing changes. For cgroup, root now can perform any operation regardless of the permissions as it was before kernfs conversion. Note that kernfs still fails unimplemented operations with -EINVAL. While at it, add comments explaining KERNFS_ROOT flags.

This driver can handle the clock controllers of the socs mentioned above, as they share a common clock tree with only small differences. The clock structure is built according to the manuals of the included SoCs and might include changes in comparison to the previous clock structure. As pll-rate-tables only the 12mhz variants are currently included. The original code was wrongly checking for 169mhz xti values [a 0 to much at the end], so the original 16mhz pll table would have never been included and its values are so obscure that I have no possibility to at least check their sane-ness. When using the formula from the manual the resulting frequency is near the table value but still slightly off.

Callers of mmc_regulator_get_supply could benefit from knowing if either of the regulators are present but not yet available. Since callers do not currently examine the return value, modify this function to return zero or -EPROBE_DEFER if either regulator get returns the same. Furthermore, since callers check vmmc/vqmmc using IS_ERR and can deal with absent regulators, switch to devm_regulator_get_optional. This has the added benefit of allowing this function to behave correctly even in the !CONFIG_REGULATOR case such that the stub can be removed.

2014-05-12xen: refactor suspend pre/post hooksDavid Vrabel1-4/+0
New architectures currently have to provide implementations of 5 different functions: xen_arch_pre_suspend(), xen_arch_post_suspend(), xen_arch_hvm_post_suspend(), xen_mm_pin_all(), and xen_mm_unpin_all(). Refactor the suspend code to only require xen_arch_pre_suspend() and xen_arch_post_suspend().

2014-05-12ext4: fix data integrity sync in ordered modeNamjae Jeon1-1/+11
When we perform a data integrity sync we tag all the dirty pages with PAGECACHE_TAG_TOWRITE at start of ext4_da_writepages. Later we check for this tag in write_cache_pages_da and creates a struct mpage_da_data containing contiguously indexed pages tagged with this tag and sync these pages with a call to mpage_da_map_and_submit. This process is done in while loop until all the PAGECACHE_TAG_TOWRITE pages are synced. We also do journal start and stop in each iteration. journal_stop could initiate journal commit which would call ext4_writepage which in turn will call ext4_bio_write_page even for delayed OR unwritten buffers. When ext4_bio_write_page is called for such buffers, even though it does not sync them but it clears the PAGECACHE_TAG_TOWRITE of the corresponding page and hence these pages are also not synced by the currently running data integrity sync. We will end up with dirty pages although sync is completed. This could cause a potential data loss when the sync call is followed by a truncate_pagecache call, which is exactly the case in collapse_range. (It will cause generic/127 failure in xfstests) To avoid this issue, we can use set_page_writeback_keepwrite instead of set_page_writeback, which doesn't clear TOWRITE tag.

Controller: add CNTLID, AVSCC, APSTA, NVSCC, ACWU, SGLS fields. Namespace: add NMIC, RESCAP, EUI64 fields. EUI64 is specifically interesting, since it can be used to construct an UEFI NVMe device path for a boot entry.
