This 1) Enables core DRM syncobj support. 2) Adds options to the submission ioctl to wait/signal syncobjs. Just like the wait fence fd, this does inline waits. Using the scheduler would be nice but I believe it is out of scope for this work. Support for timeline syncobjs is implemented and the interface is ready for it, but I'm not enabling it yet until there is some code for turnip to use it. The reset is mostly in there because in the presence of waiting and signalling the same semaphores, resetting them after signalling can become very annoying. v2: - Fixed style issues - Removed a cleanup issue in a failure case - Moved to a copy_from_user per syncobj v3: - Fixed a missing declaration introduced in v2 - Reworked to use ERR_PTR/PTR_ERR - Simplified failure gotos.

Pull iommu fixes from Joerg Roedel: - Race condition fixes for the AMD IOMMU driver. These are five patches fixing two race conditions around increase_address_space(). The first race condition was around the non-atomic update of the domain page-table root pointer and the variable containing the page-table depth (called mode). This is fixed now be merging page-table root and mode into one 64-bit field which is read/written atomically. The second race condition was around updating the page-table root pointer and making it public before the hardware caches were flushed. This could cause addresses to be mapped and returned to drivers which are not reachable by IOMMU hardware yet, causing IO page-faults. This is fixed too by adding the necessary flushes before a new page-table root is published. Related to the race condition fixes these patches also add a missing domain_flush_complete() barrier to update_domain() and a fix to bail out of the loop which tries to increase the address space when the call to increase_address_space() fails. Qian was able to trigger the race conditions under high load and memory pressure within a few days of testing. He confirmed that he has seen no issues anymore with the fixes included here. - Fix for a list-handling bug in the VirtIO IOMMU driver. * tag 'iommu-fixes-v5.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: iommu/virtio: Reverse arguments to list_add iommu/amd: Do not flush Device Table in iommu_map_page() iommu/amd: Update Device Table in increase_address_space() iommu/amd: Call domain_flush_complete() in update_domain() iommu/amd: Do not loop forever when trying to increase address space iommu/amd: Fix race in increase_address_space()/fetch_pte()

It seems that for whatever reason, gcc-10 ends up not inlining a couple of functions that used to be inlined before. Even if they only have one single callsite - it looks like gcc may have decided that the code was unlikely, and not worth inlining. The code generation difference is harmless, but caused a few new section mismatch errors, since the (now no longer inlined) function wasn't in the __init section, but called other init functions: Section mismatch in reference from the function kexec_free_initrd() to the function .init.text:free_initrd_mem() Section mismatch in reference from the function tpm2_calc_event_log_size() to the function .init.text:early_memremap() Section mismatch in reference from the function tpm2_calc_event_log_size() to the function .init.text:early_memunmap() So add the appropriate __init annotation to make modpost not complain. In both cases there were trivially just a single callsite from another __init function. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

gcc-10 has started warning about conflicting types for a few new built-in functions, particularly 'free()'. This results in warnings like: crypto/xts.c:325:13: warning: conflicting types for built-in function ‘free’; expected ‘void(void *)’ [-Wbuiltin-declaration-mismatch] because the crypto layer had its local freeing functions called 'free()'. Gcc-10 is in the wrong here, since that function is marked 'static', and thus there is no chance of confusion with any standard library function namespace. But the simplest thing to do is to just use a different name here, and avoid this gcc mis-feature. [ Side note: gcc knowing about 'free()' is in itself not the mis-feature: the semantics of 'free()' are special enough that a compiler can validly do special things when seeing it. So the mis-feature here is that gcc thinks that 'free()' is some restricted name, and you can't shadow it as a local static function. Making the special 'free()' semantics be a function attribute rather than tied to the name would be the much better model ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

gcc-10 now warns about passing aliasing pointers to functions that take restricted pointers. That's actually a great warning, and if we ever start using 'restrict' in the kernel, it might be quite useful. But right now we don't, and it turns out that the only thing this warns about is an idiom where we have declared a few functions to be "printf-like" (which seems to make gcc pick up the restricted pointer thing), and then we print to the same buffer that we also use as an input. And people do that as an odd concatenation pattern, with code like this: #define sysfs_show_gen_prop(buffer, fmt, ...) \ snprintf(buffer, PAGE_SIZE, "%s"fmt, buffer, __VA_ARGS__) where we have 'buffer' as both the destination of the final result, and as the initial argument. Yes, it's a bit questionable. And outside of the kernel, people do have standard declarations like int snprintf( char *restrict buffer, size_t bufsz, const char *restrict format, ... ); where that output buffer is marked as a restrict pointer that cannot alias with any other arguments. But in the context of the kernel, that 'use snprintf() to concatenate to the end result' does work, and the pattern shows up in multiple places. And we have not marked our own version of snprintf() as taking restrict pointers, so the warning is incorrect for now, and gcc picks it up on its own. If we do start using 'restrict' in the kernel (and it might be a good idea if people find places where it matters), we'll need to figure out how to avoid this issue for snprintf and friends. But in the meantime, this warning is not useful. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

When the controller is reconnecting, the host fails I/O and admin commands as the host cannot reach the controller. ns scanning may revalidate namespaces during that period and it is wrong to remove namespaces due to these failures as we may hang (see 205da243). One command that may fail is nvme_identify_ns_descs. Since we return success due to having ns identify descriptor list optional, we continue to compare ns identifiers in nvme_revalidate_disk, obviously fail and return -ENODEV to nvme_validate_ns, which will remove the namespace. Exactly what we don't want to happen.

This is another fine warning, related to the 'zero-length-bounds' one, but hitting the same historical code in the kernel. Because C didn't historically support flexible array members, we have code that instead uses a one-sized array, the same way we have cases of zero-sized arrays. The one-sized arrays come from either not wanting to use the gcc zero-sized array extension, or from a slight convenience-feature, where particularly for strings, the size of the structure now includes the allocation for the final NUL character. So with a "char name[1];" at the end of a structure, you can do things like v = my_malloc(sizeof(struct vendor) + strlen(name)); and avoid the "+1" for the terminator. Yes, the modern way to do that is with a flexible array, and using 'offsetof()' instead of 'sizeof()', and adding the "+1" by hand. That also technically gets the size "more correct" in that it avoids any alignment (and thus padding) issues, but this is another long-term cleanup thing that will not happen for 5.7. So disable the warning for now, even though it's potentially quite useful. Having a slew of warnings that then hide more urgent new issues is not an improvement.

This is a fine warning, but we still have a number of zero-length arrays in the kernel that come from the traditional gcc extension. Yes, they are getting converted to flexible arrays, but in the meantime the gcc-10 warning about zero-length bounds is very verbose, and is hiding other issues. I missed one actual build failure because it was hidden among hundreds of lines of warning. Thankfully I caught it on the second go before pushing things out, but it convinced me that I really need to disable the new warnings for now. We'll hopefully be all done with our conversion to flexible arrays in the not too distant future, and we can then re-enable this warning. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

We have some rather random rules about when we accept the "maybe-initialized" warnings, and when we don't. For example, we consider it unreliable for gcc versions < 4.9, but also if -O3 is enabled, or if optimizing for size. And then various kernel config options disabled it, because they know that they trigger that warning by confusing gcc sufficiently (ie PROFILE_ALL_BRANCHES). And now gcc-10 seems to be introducing a lot of those warnings too, so it falls under the same heading as 4.9 did. At the same time, we have a very straightforward way to _enable_ that warning when wanted: use "W=2" to enable more warnings. So stop playing these ad-hoc games, and just disable that warning by default, with the known and straight-forward "if you want to work on the extra compiler warnings, use W=123". Would it be great to have code that is always so obvious that it never confuses the compiler whether a variable is used initialized or not? Yes, it would. In a perfect world, the compilers would be smarter, and our source code would be simpler. That's currently not the world we live in, though.

So exchange the arguments on the list_add call to put the list head in the second argument.
