Hi, While we are looking at the printk issue, I see that its printk'ing the EOE (end of event) records which is really not something that we need in syslog.

On the latest kernels if one was to load about 15 rules, set the failure state to panic, and then run service auditd stop the kernel will panic. This is because auditd stops, then the script deletes all of the rules. These deletions are sent as audit messages out of the printk kernel interface which is already known to be lossy. These will overun the default kernel rate limiting (10 really fast messages) and will call audit_panic(). The same effect can happen if a slew of avc's come through while auditd is stopped. This can be fixed a number of ways but this patch fixes the problem by just not panicing if auditd is not running. We know printk is lossy and if the user chooses to set the failure mode to panic and tries to use printk we can't make any promises no matter how hard we try, so why try? At least in this way we continue to get lost message accounting and will eventually know that things went bad. The other change is to add a new call to audit_log_lost() if auditd disappears. We already pulled the skb off the queue and couldn't send it so that message is lost. At least this way we will account for the last message and panic if the machine is configured to panic. This code path should only be run if auditd dies for unforeseen reasons. If auditd closes correctly audit_pid will get set to 0 and we won't walk this code path.

Eric Sandeen tracked an XFS on ARM corruption bug down to a function under fs/xfs/ involving some get_unaligned() calls on u64 pointers. As it turns out, calling ARM's get_unaligned() on a u64 pointer pointing to the following byte sequence: 80 81 82 83 84 85 86 87 would return ffffffff83828180 (LE mode.) This turns out to be because of implicit u8 -> int promotion in ARM's implementation of various helpers for get_unaligned(), causing them to accidentally return signed instead of unsigned values, which in turn caused the subsequent casts to unsigned long long in __get_unaligned_8_[bl]e() to sign-extend the lower words. Fix by casting the return values of __get_unaligned_[24]_[bl]e() to unsigned int.

This per-CPU access needs to be done in such a way as to guarantee that the code using it cannot move to some other CPU before all uses of the value accessed have completed.

avoid over-eager large page splitup. When the target area needs to be split or is split already (ioremap) then the current code enforces the split of large mappings in the alias regions even if we could avoid it. Use a separate variable processed in the cpa_data structure to carry the number of pages which have been processed instead of reusing the numpages variable.

I recently stumbled upon a problem in the support for huge pages. If a program using huge pages does not explicitly unmap them, they remain mapped (and therefore, are lost) after the program exits. I observed that the free huge page count in /proc/meminfo decreased when running my program, and it did not increase after the program exited. After running the program a few times, no more huge pages could be allocated. The reason for this seems to be that the x86 pmd_bad and pud_bad consider pmd/pud entries having the PSE bit set invalid. I think there is nothing wrong with this bit being set, it just indicates that the lowest level of translation has been reached. This bit has to be (and is) checked after the basic validity of the entry has been checked, like in this fragment from follow_page() in mm/memory.c: if (pmd_none(*pmd) || unlikely(pmd_bad(*pmd))) goto no_page_table; if (pmd_huge(*pmd)) { BUG_ON(flags & FOLL_GET); page = follow_huge_pmd(mm, address, pmd, flags & FOLL_WRITE); goto out; } Note that this code currently doesn't work as intended if the pmd refers to a huge page, the pmd_huge() check can not be reached if the page is huge. Extending pmd_bad() (and, for future 1GB page support, pud_bad()) to allow for the PSE bit being set fixes this. For similar reasons, allowing the NX bit being set is necessary, too. I have seen huge pages having the NX bit set in their pmd entry, which would cause the same problem.
