2022-01-07Revert "i2c: core: support bus regulator controlling in adapter"Wolfram Sang
This largely reverts commit 5a7b95fb993ec399c8a685552aa6a8fc995c40bd. It breaks suspend with AMD GPUs, and we couldn't incrementally fix it. So, let's remove the code and go back to the drawing board. We keep the header extension to not break drivers already populating the regulator. We expect to re-add the code handling it soon.

2022-01-07Revert "libtraceevent: Increase libtraceevent logging when verbose"Arnaldo Carvalho de Melo
This reverts commit 08efcb4a638d260ef7fcbae64ecf7ceceb3f1841. This breaks the build as it will prefer using libbpf-devel header files, even when not using LIBBPF_DYNAMIC=1, breaking the build.

sense to When running 'perf trace' with an BPF object like: # perf trace -e openat,tools/perf/examples/bpf/hello.c the event parsing eventually calls llvm__get_kbuild_opts() that runs a script and that ends up with SIGCHLD delivered to the 'perf trace' handler, which assumes the workload process is done and quits 'perf trace'. Move the SIGCHLD handler setup directly to trace__run(), where the event is parsed and the object is already compiled.

2022-01-07regmap: Call regmap_debugfs_exit() prior to _init()Fabio Estevam
Since commit cffa4b2122f5 ("regmap: debugfs: Fix a memory leak when calling regmap_attach_dev"), the following debugfs error is seen on i.MX boards: debugfs: Directory 'dummy-iomuxc-gpr@20e0000' with parent 'regmap' already present! In the attempt to fix the memory leak, the above commit added a NULL check for map->debugfs_name. For the first debufs entry, map->debugfs_name is NULL and then the new name is allocated via kasprintf(). For the second debugfs entry, map->debugfs_name() is no longer NULL, so it will keep using the old entry name and the duplicate name error is seen. Quoting Mark Brown: "That means that if the device gets freed we'll end up with the old debugfs file hanging around pointing at nothing. ... To be more explicit this means we need a call to regmap_debugfs_exit() which will clean up all the existing debugfs stuff before we loose references to it." Call regmap_debugfs_exit() prior to regmap_debugfs_init() to fix the problem. Tested on i.MX6Q and i.MX6SX boards.

2022-01-07i40e: Minimize amount of busy-waiting during AQ sendJedrzej Jagielski
The i40e_asq_send_command will now use a non blocking usleep_range if possible (non-atomic context), instead of busy-waiting udelay. The usleep_range function uses hrtimers to provide better performance and removes the negative impact of busy-waiting in time-critical environments. 1. Rename i40e_asq_send_command to i40e_asq_send_command_atomic and add 5th parameter to inform if called from an atomic context. Call inside usleep_range (if non-atomic) or udelay (if atomic). 2. Change i40e_asq_send_command to invoke i40e_asq_send_command_atomic(..., false). 3. Change two functions: - i40e_aq_set_vsi_uc_promisc_on_vlan - i40e_aq_set_vsi_mc_promisc_on_vlan to explicitly use i40e_asq_send_command_atomic(..., true) instead of i40e_asq_send_command, as they use spinlocks and do some work in an atomic context. All other calls to i40e_asq_send_command remain unchanged.

2022-01-07x86/sgx: Fix NULL pointer dereference on non-SGX systemsDave Hansen
== Problem == Nathan Chancellor reported an oops when aceessing the 'sgx_total_bytes' sysfs file: https://lore.kernel.org/all/YbzhBrimHGGpddDM@archlinux-ax161/ The sysfs output code accesses the sgx_numa_nodes[] array unconditionally. However, this array is allocated during SGX initialization, which only occurs on systems where SGX is supported. If the sysfs file is accessed on systems without SGX support, sgx_numa_nodes[] is NULL and an oops occurs. == Solution == To fix this, hide the entire nodeX/x86/ attribute group on systems without SGX support using the ->is_visible attribute group callback. Unfortunately, SGX is initialized via a device_initcall() which occurs _after_ the ->is_visible() callback. Instead of moving SGX initialization earlier, call sysfs_update_group() during SGX initialization to update the group visiblility. This update requires moving the SGX sysfs code earlier in sgx/main.c. There are no code changes other than the addition of arch_update_sysfs_visibility() and a minor whitespace fixup to arch_node_attr_is_visible() which checkpatch caught.

2022-01-07docs: automarkup.py: Fix invalid HTML link output and broken URI fragmentsJames Clark
Since commit d18b01789ae5 ("docs: Add automatic cross-reference for documentation pages"), references that were already explicitly defined with "ref:" and referred to other pages with a path have been doubled. This is reported as the following error by Firefox: Start tag "a" seen but an element of the same type was already open. End tag "a" violates nesting rules. As well as the invalid HTML, this also obscures the URI fragment links to subsections because the second link overrides the first. For example on the page admin-guide/hw-vuln/mds.html the last link should be to the "Default Mitigations" subsection using a # URI fragment: admin-guide/hw-vuln/l1tf.html#default-mitigations But it is obsured by a second link to the whole page: admin-guide/hw-vuln/l1tf.html The full HTML with the double <a> tags looks like this: <a class="reference internal" href="l1tf.html#default-mitigations"> <span class="std std-ref"> <a class="reference internal" href="l1tf.html"> <span class="doc">L1TF - L1 Terminal Fault</span> </a> </span> </a> After this commit, there is only a single link: <a class="reference internal" href="l1tf.html#default-mitigations"> <span class="std std-ref">Documentation/admin-guide/hw-vuln//l1tf.rst</span> </a> Now that the second link is removed, the browser correctly jumps to the default-mitigations subsection when clicking the link. The fix is to check that nodes in the document to be modified are not already references. A reference is counted as any text that is a descendant of a reference type node. Only plain text should be converted to new references, otherwise the doubling occurs. Testing ======= * Test that the build stdout is the same (ignoring ordering), and that no new warnings are printed. * Diff all .html files and check that the only modifications occur to the bad double links. * The auto linking of bare references to pages without "ref:" is still working.

When writing to the server from afs_writepage() or afs_writepages(), copy the data to the cache object too. To make this possible, the cookie must have its active users count incremented when the page is dirtied and kept incremented until we manage to clean up all the pages. This allows the writeback to take place after the last file struct is released.

2022-01-07afs: Convert afs to use the new fscache APIDavid Howells
Change the afs filesystem to support the new afs driver. The following changes have been made: (1) The fscache_netfs struct is no more, and there's no need to register the filesystem as a whole. There's also no longer a cell cookie. (2) The volume cookie is now an fscache_volume cookie, allocated with fscache_acquire_volume(). This function takes three parameters: a string representing the "volume" in the index, a string naming the cache to use (or NULL) and a u64 that conveys coherency metadata for the volume. For afs, I've made it render the volume name string as: "afs,<cell>,<volume_id>" and the coherency data is currently 0. (3) The fscache_cookie_def is no more and needed information is passed directly to fscache_acquire_cookie(). The cache no longer calls back into the filesystem, but rather metadata changes are indicated at other times. fscache_acquire_cookie() is passed the same keying and coherency information as before, except that these are now stored in big endian form instead of cpu endian. This makes the cache more copyable. (4) fscache_use_cookie() and fscache_unuse_cookie() are called when a file is opened or closed to prevent a cache file from being culled and to keep resources to hand that are needed to do I/O. fscache_use_cookie() is given an indication if the cache is likely to be modified locally (e.g. the file is open for writing). fscache_unuse_cookie() is given a coherency update if we had the file open for writing and will update that. (5) fscache_invalidate() is now given uptodate auxiliary data and a file size. It can also take a flag to indicate if this was due to a DIO write. This is wrapped into afs_fscache_invalidate() now for convenience. (6) fscache_resize() now gets called from the finalisation of afs_setattr(), and afs_setattr() does use/unuse of the cookie around the call to support this. (7) fscache_note_page_release() is called from afs_release_page(). (8) Use a killable wait in nfs_vm_page_mkwrite() when waiting for PG_fscache to be cleared. Render the parts of the cookie key for an afs inode cookie as big endian. Changes ======= ver #2: - Use gfpflags_allow_blocking() rather than using flag directly. - fscache_acquire_volume() now returns errors.

2022-01-07cachefiles: Implement the I/O routinesDavid Howells
Implement the I/O routines for cachefiles. There are two sets of routines here: preparation and actual I/O. Preparation for read involves looking to see whether there is data present, and how much. Netfslib tells us what it wants us to do and we have the option of adjusting shrinking and telling it whether to read from the cache, download from the server or simply clear a region. Preparation for write involves checking for space and defending against possibly running short of space, if necessary punching out a hole in the file so that we don't leave old data in the cache if we update the coherency information. Then there's a read routine and a write routine. They wait for the cookie state to move to something appropriate and then start a potentially asynchronous direct I/O operation upon it.
