The IBM asm driver is using a kobject only for reference counting, nothing else. So switch it to use a kref instead, which is all that is needed, and is much smaller. Cc: Max Asböck <amax@us.ibm.com> Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by:Greg Kroah-Hartman <gregkh@suse.de>

Instead of walking from the source down to the root of sysfs, and back to the target, we stop at the first directory the source and the target share. This link: /devices/pci0000:00/0000:00:1d.7/usb1/1-0:1.0/ep_81 pointed to: ../../../../../devices/pci0000:00/0000:00:1d.0/usb2/2-0:1.0/usb_endpoint/usbdev2.1_ep81 now it just points to: usb_endpoint/usbdev1.1_ep81 Thanks to Denis Cheng for bringing this up, and sending the initial patch.

It isn't that hard to add simple kset attributes, so don't go through all the gyrations of creating your own object type and show and store functions. Just use the functions that are already present. This makes things much simpler. Note, the version_str string violates the "one value per file" rule for sysfs. I suggest changing this now (individual files per type supported is one suggested way.)

This patch reorganizes the way suspend and resume notifications are sent to drivers. The major changes are that now the PM core acquires every device semaphore before calling the methods, and calls to device_add() during suspends will fail, while calls to device_del() during suspends will block. It also provides a way to safely remove a suspended device with the help of the PM core, by using the device_pm_schedule_removal() callback introduced specifically for this purpose, and updates two drivers (msr and cpuid) that need to use it.

Before transmission of the last word in PIO RX_ONLY mode rx+tx mode is enabled: /* prevent last RX_ONLY read from triggering * more word i/o: switch to rx+tx */ if (c == 0 && tx == NULL) mcspi_write_cs_reg(spi, OMAP2_MCSPI_CHCONF0, l); But because c is decremented after the test, c will never be zero and rx+tx will not be enabled. This breaks RX_ONLY mode PIO transfers. Fix it by decrementing c in the beginning of the various I/O loops. Signed-off-by:

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:

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.
