2012-01-12Merge branch 'akpm' (aka "Andrew's patch-bomb, take two")Linus Torvalds
Andrew explains: - various misc stuff - Most of the rest of MM: memcg, threaded hugepages, others. - cpumask - kexec - kdump - some direct-io performance tweaking - radix-tree optimisations - new selftests code A note on this: often people will develop a new userspace-visible feature and will develop userspace code to exercise/test that feature. Then they merge the patch and the selftest code dies. Sometimes we paste it into the changelog. Sometimes the code gets thrown into Documentation/(!). This saddens me. So this patch creates a bare-bones framework which will henceforth allow me to ask people to include their test apps in the kernel tree so we can keep them alive. Then when people enhance or fix the feature, I can ask them to update the test app too. The infrastruture is terribly trivial at present - let's see how it evolves. - checkpoint/restart feature work. A note on this: this is a project by various mad Russians to perform c/r mainly from userspace, with various oddball helper code added into the kernel where the need is demonstrated. So rather than some large central lump of code, what we have is little bits and pieces popping up in various places which either expose something new or which permit something which is normally kernel-private to be modified. The overall project is an ongoing thing. I've judged that the size and scope of the thing means that we're more likely to be successful with it if we integrate the support into mainline piecemeal rather than allowing it all to develop out-of-tree. However I'm less confident than the developers that it will all eventually work! So what I'm asking them to do is to wrap each piece of new code inside CONFIG_CHECKPOINT_RESTORE. So if it all eventually comes to tears and the project as a whole fails, it should be a simple matter to go through and delete all trace of it. This lot pretty much wraps up the -rc1 merge for me. * akpm: (96 commits) unlzo: fix input buffer free ramoops: update parameters only after successful init ramoops: fix use of rounddown_pow_of_two() c/r: prctl: add PR_SET_MM codes to set up mm_struct entries c/r: procfs: add start_data, end_data, start_brk members to /proc/$pid/stat v4 c/r: introduce CHECKPOINT_RESTORE symbol selftests: new x86 breakpoints selftest selftests: new very basic kernel selftests directory radix_tree: take radix_tree_path off stack radix_tree: remove radix_tree_indirect_to_ptr() dio: optimize cache misses in the submission path vfs: cache request_queue in struct block_device fs/direct-io.c: calculate fs_count correctly in get_more_blocks() drivers/parport/parport_pc.c: fix warnings panic: don't print redundant backtraces on oops sysctl: add the kernel.ns_last_pid control kdump: add udev events for memory online/offline include/linux/crash_dump.h needs elf.h kdump: fix crash_kexec()/smp_send_stop() race in panic() kdump: crashk_res init check for /sys/kernel/kexec_crash_size ...

2012-01-12kdump: add udev events for memory online/offlineMichael Holzheu
Currently no udev events for memory hotplug "online" and "offline" are generated: # udevadm monitor # echo offline > /sys/devices/system/memory/memory4/state ==> No event When kdump is loaded, kexec detects the current memory configuration and stores it in the pre-allocated ELF core header. Therefore, for kdump it is necessary to reload the kdump kernel with kexec when the memory configuration changes (e.g. for online/offline hotplug memory). In order to do this automatically, udev rules should be used. This kernel patch adds udev events for "online" and "offline". Together with this kernel patch, the following udev rules for online/offline have to be added to "/etc/udev/rules.d/98-kexec.rules": SUBSYSTEM=="memory", ACTION=="online", PROGRAM="/etc/init.d/kdump restart" SUBSYSTEM=="memory", ACTION=="offline", PROGRAM="/etc/init.d/kdump restart" [sfr@canb.auug.org.au: fixups for class to subsystem conversion] Signed-off-by: Michael Holzheu <holzheu@linux.vnet.ibm.com> Cc: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: Vivek Goyal <vgoyal@redhat.com> Cc: "Eric W.

2012-01-12gianfar: Fix invalid TX frames returned on error queue when time stampingManfred Rudigier
When TX time stamping for PTP messages is enabled on a socket, a time stamp is returned on the socket error queue to the user space application after the frame was transmitted. The transmitted frame is also returned on the error queue so that an application knows to which frame the time stamp belongs. In the current implementation the TxFCB is immediately followed by the frame. Since the eTSEC inserts the TX time stamp 8 bytes after the TxFCB, parts of the frame have been overwritten and an invalid frame was returned on the socket error queue. This patch fixes the described problem by adding additional 16 padding bytes between the TxFCB and the frame for all messages sent from a time stamping enabled socket (other sockets are not affected).

2012-01-12gianfar: Fix missing sock reference when processing TX time stampsManfred Rudigier
When there is not enough headroom in the skb a private copy will be made. However, the private copy had no reference to the socket and consequently no time stamp could be queued on the socket error queue during the skb_tstamp_tx function. This patch fixes this issue by also stealing the sock reference from the original skb after making the private copy.

2012-01-12phylib: introduce mdiobus_alloc_size()Timur Tabi
Introduce function mdiobus_alloc_size() as an alternative to mdiobus_alloc(). Most callers of mdiobus_alloc() also allocate a private data structure, and then manually point bus->priv to this object. mdiobus_alloc_size() combines the two operations into one, which simplifies memory management. The original mdiobus_alloc() now just calls mdiobus_alloc_size(0). Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-01-12brcmsmac: fix reading of PCI sprom contentsLinus Torvalds
It appears that you can only read the sprom contents with aligned 16-bit reads: anything else causes at least some versions of the broadcom chipset to abort the PCI transaction, returning 0xff. This apparently doesn't trigger very often, because most setups don't use an external srom chip, and the OTP sprom loading doesn't have this issue. But at least the current 11" Macbook Air does trigger it, and wireless communications were broken as a result.

2012-01-12mmc: fix a deadlock between system suspend and MMC block IOGuennadi Liakhovetski
Performing MMC block IO with simultaneous STR can lead to a deadlock: the mmc_pm_notify() function claims the host and then calls bus .remove() method, which lands in mmc_blk_remove(), which calls mmc_blk_remove_req() then it goes to -> mmc_cleanup_queue() -> kthread_stop(), which waits for the mmc-block thread to stop. If the mmc-block thread at that time is processing block requests, it will also try to claim the host in mmc_blk_issue_rq() and block there. This patch fixes the problem by calling .remove() before claiming the host.

2012-01-12lguest: switch segment-voodoo-numbers to readable symbolsJacek Galowicz
When studying lguest's x86 segment descriptor code, it is not longer necessary to have the Intel x86 architecture manual open on the page with the segment descriptor illustration to understand the crazy numbers assigned to both descriptor structure halves a/b. Now the struct desc_struct's fields, like suggested by Glauber de Oliveira Costa in 2008, are used.

2012-01-12virtio: balloon: Add freeze, restore handlers to support S4Amit Shah
Handling balloon hibernate / restore is tricky. If the balloon was inflated before going into the hibernation state, upon resume, the host will not have any memory of that. Any pages that were passed on to the host earlier would most likely be invalid, and the host will have to re-balloon to the previous value to get in the pre-hibernate state. So the only sane thing for the guest to do here is to discard all the pages that were put in the balloon. When to discard the pages is the next question. One solution is to deflate the balloon just before writing the image to the disk (in the freeze() PM callback). However, asking for pages from the host just to discard them immediately after seems wasteful of resources. Hence, it makes sense to do this by just fudging our counters soon after wakeup. This means we don't deflate the balloon before sleep, and also don't put unnecessary pressure on the host. This also helps in the thaw case: if the freeze fails for whatever reason, the balloon should continue to remain in the inflated state. This was tested by issuing 'swapoff -a' and trying to go into the S4 state. That fails, and the balloon stays inflated, as expected. Both the host and the guest are happy. Finally, in the restore() callback, we empty the list of pages that were previously given off to the host, add the appropriate number of pages to the totalram_pages counter, reset the num_pages counter to 0, and all is fine. As a last step, delete the vqs on the freeze callback to prepare for hibernation, and re-create them in the restore and thaw callbacks to resume normal operation. The kthread doesn't race with any operations here, since it's frozen before the freeze() call and is thawed after the thaw() and restore() callbacks, so we're safe with that.
