This reverts commit 81100eb8 for the release, to avoid the unnecessary warning noise that is only really relevant to wireless driver developers. The warning will probably go right back in after I cut the release, but at least we won't unnecessarily worry users. Acked-by: John W.

The shared page table code for hugetlb memory on x86 and x86_64 is causing a leak. When a user of hugepages exits using this code the system leaks some of the hugepages. ------------------------------------------------------- Part of /proc/meminfo just before database startup: HugePages_Total: 5500 HugePages_Free: 5500 HugePages_Rsvd: 0 Hugepagesize: 2048 kB Just before shutdown: HugePages_Total: 5500 HugePages_Free: 4475 HugePages_Rsvd: 0 Hugepagesize: 2048 kB After shutdown: HugePages_Total: 5500 HugePages_Free: 4988 HugePages_Rsvd: 0 Hugepagesize: 2048 kB ---------------------------------------------------------- The problem occurs durring a fork, in copy_hugetlb_page_range(). It locates the dst_pte using huge_pte_alloc(). Since huge_pte_alloc() calls huge_pmd_share() it will share the pmd page if can, yet the main loop in copy_hugetlb_page_range() does a get_page() on every hugepage. This is a violation of the shared hugepmd pagetable protocol and creates additional referenced to the hugepages causing a leak when the unmap of the VMA occurs. We can skip the entire replication of the ptes when the hugepage pagetables are shared. The attached patch skips copying the ptes and the get_page() calls if the hugetlbpage pagetable is shared.

Michael Wu noticed in his lkml post at http://marc.info/?l=linux-kernel&m=119396182726091&w=2 that certain wireless drivers ended up having their name in module memory, which would then crash the kernel on module unload. The patch he proposed was a bit clumsy in that it increased the size of a lockdep entry significantly; the patch below tries another approach, it checks, on module teardown, if the name of a class is in module space and then zaps the class. This is very similar to what we already do with keys that are in module space.

This DMI blacklist reduces the console messages on systems which have a BIOS that invokes OSI(Linux). As the DMI blacklist already knows about these systems, the request for DMI info itself is disabled. Further, if OSI(Linux) has already been determined to have no beneift, we disable the console message requesting acpi_osi=Linux test results. Signed-off-by: Len Brown <len.brown@intel.com>

Linux does not want BIOS writers to invoke _OSI(Linux) - for in the field it causes more Windows incompatibility problems than it solves. So when it is seen in the BIOS for an Intel Customer Reference Board, Linux should ignore its effect by default, and should complain loudly. Otherwise, the reference BIOS will go unfixed, and the bad BIOS will spread to the field. Users of this board can get the old behavior with "acpi_osi=Linux" As this was the only entry, delete acpi_osl_dmi_table[]. Signed-off-by: Len Brown <len.brown@intel.com>

I've verified (on my Initio 9100 with a DAT drive) that the 2.6.24-rc8-git6 initio module still hangs on loading. These fixes (other than the printk) are needed to get the module to load ok (and work correctly) with my adapter & tape drive. a) printk cosmetic fix b) cblk->sglen needs setting for later DMA I/O routines to use c) host->bios_addr needs setting for debug output correctness d) semaph & semaph_lock initialisation had got lost since 2.6.22 e) since 2.6.22 the bios data address was truncated to 16 bits (needs 20 when shifted left) Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

As it is ip_append_data only counts page fragments to the skb that allocated it. As such it means that the first skb gets hit with a 4K charge even though it might have only used a fraction of it while all subsequent skb's that use the same page gets away with no charge at all.
