Trinity is now hitting the WARN_ON_ONCE we added in v3.15 commit cda540ac ("mm: get_user_pages(write,force) refuse to COW in shared areas"). The warning has served its purpose, nobody was harmed by that change, so just remove the warning to generate less noise from Trinity. Which reminds me of the comment I wrongly left behind with that commit (but was spotted at the time by Kirill), which has since moved into a separate function, and become even more obscure: delete it.

Enclosing '#include <linux/acpi.h>' within '#ifdef CONFIG_ACPI' is unnecessary, since it has its own conditional compile for CONFIG_ACPI. Commit 0fbcf4af ("ipmi: Convert the IPMI SI ACPI handling to a platform device") exposed this as a problem for platforms that do not support ACPI when it introduced a call to ACPI_PTR() macro outside of the CONFIG_ACPI conditional compile. This would have been perfectly acceptable if acpi.h were not conditionally excluded for the non-acpi platform, because the conditional compile within acpi.h defines ACPI_PTR() to return NULL when compiled for non acpi platforms.

We allocate a pgtable but do not attach it to anything if the PMD is in a DAX VMA, causing it to leak. We certainly try to not free pgtables associated with the huge zero page if the zero page is in a DAX VMA, so I think this is the right solution. This needs to be properly audited. Signed-off-by:

of_hwspin_lock_get_id() is protected by the RCU lock, which means that insertions can occur simultaneously with the lookup. If the radix tree transitions from a height of 0, we can see a slot with the indirect_ptr bit set, which will cause us to at least read random memory, and could cause other havoc. Fix this by using the newly introduced radix_tree_iter_retry(). Signed-off-by:

If the indirect_ptr bit is set on a slot, that indicates we need to redo the lookup. Introduce a new function radix_tree_iter_retry() which forces the loop to retry the lookup by setting 'slot' to NULL and turning the iterator back to point at the problematic entry. This is a pretty rare problem to hit at the moment; the lookup has to race with a grow of the radix tree from a height of 0. The consequences of hitting this race are that gang lookup could return a pointer to a radix_tree_node instead of a pointer to whatever the user had inserted in the tree.

This patch provides a way of working around a slight regression introduced by commit 84638335 ("mm: rework virtual memory accounting"). Before that commit RLIMIT_DATA have control only over size of the brk region. But that change have caused problems with all existing versions of valgrind, because it set RLIMIT_DATA to zero. This patch fixes rlimit check (limit actually in bytes, not pages) and by default turns it into warning which prints at first VmData misuse: "mmap: top (795): VmData 516096 exceed data ulimit 512000. Will be forbidden soon." Behavior is controlled by boot param ignore_rlimit_data=y/n and by sysfs /sys/module/kernel/parameters/ignore_rlimit_data. For now it set to "y".

Commit b7643757 ("procfs: mark thread stack correctly in proc/<pid>/maps") added [stack:TID] annotation to /proc/<pid>/maps. Finding the task of a stack VMA requires walking the entire thread list, turning this into quadratic behavior: a thousand threads means a thousand stacks, so the rendering of /proc/<pid>/maps needs to look at a million combinations. The cost is not in proportion to the usefulness as described in the patch. Drop the [stack:TID] annotation to make /proc/<pid>/maps (and /proc/<pid>/numa_maps) usable again for higher thread counts. The [stack] annotation inside /proc/<pid>/task/<tid>/maps is retained, as identifying the stack VMA there is an O(1) operation. Siddesh said: "The end users needed a way to identify thread stacks programmatically and there wasn't a way to do that. I'm afraid I no longer remember (or have access to the resources that would aid my memory since I changed employers) the details of their requirement. However, I did do this on my own time because I thought it was an interesting project for me and nobody really gave any feedback then as to its utility, so as far as I am concerned you could roll back the main thread maps information since the information is available in the thread-specific files" Signed-off-by:

When working with hugetlbfs ptes (which are actually pmds) is not valid to directly use pte functions like pte_present() because the hardware bit layout of pmds and ptes can be different. This is the case on s390. Therefore we have to convert the hugetlbfs ptes first into a valid pte encoding with huge_ptep_get(). Currently the /proc/<pid>/numa_maps code uses hugetlbfs ptes without huge_ptep_get(). On s390 this leads to the following two problems: 1) The pte_present() function returns false (instead of true) for PROT_NONE hugetlb ptes. Therefore PROT_NONE vmas are missing completely in the "numa_maps" output. 2) The pte_dirty() function always returns false for all hugetlb ptes. Therefore these pages are reported as "mapped=xxx" instead of "dirty=xxx". Therefore use huge_ptep_get() to correctly convert the hugetlb ptes. Signed-off-by:
