git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal Pull big execve/kernel_thread/fork unification series from Al Viro: "All architectures are converted to new model. Quite a bit of that stuff is actually shared with architecture trees; in such cases it's literally shared branch pulled by both, not a cherry-pick. A lot of ugliness and black magic is gone (-3KLoC total in this one): - kernel_thread()/kernel_execve()/sys_execve() redesign. We don't do syscalls from kernel anymore for either kernel_thread() or kernel_execve(): kernel_thread() is essentially clone(2) with callback run before we return to userland, the callbacks either never return or do successful do_execve() before returning. kernel_execve() is a wrapper for do_execve() - it doesn't need to do transition to user mode anymore. As a result kernel_thread() and kernel_execve() are arch-independent now - they live in kernel/fork.c and fs/exec.c resp. sys_execve() is also in fs/exec.c and it's completely architecture-independent. - daemonize() is gone, along with its parts in fs/*.c - struct pt_regs * is no longer passed to do_fork/copy_process/ copy_thread/do_execve/search_binary_handler/->load_binary/do_coredump. - sys_fork()/sys_vfork()/sys_clone() unified; some architectures still need wrappers (ones with callee-saved registers not saved in pt_regs on syscall entry), but the main part of those suckers is in kernel/fork.c now." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal: (113 commits) do_coredump(): get rid of pt_regs argument print_fatal_signal(): get rid of pt_regs argument ptrace_signal(): get rid of unused arguments get rid of ptrace_signal_deliver() arguments new helper: signal_pt_regs() unify default ptrace_signal_deliver flagday: kill pt_regs argument of do_fork() death to idle_regs() don't pass regs to copy_process() flagday: don't pass regs to copy_thread() bfin: switch to generic vfork, get rid of pointless wrappers xtensa: switch to generic clone() openrisc: switch to use of generic fork and clone unicore32: switch to generic clone(2) score: switch to generic fork/vfork/clone c6x: sanitize copy_thread(), get rid of clone(2) wrapper, switch to generic clone() take sys_fork/sys_vfork/sys_clone prototypes to linux/syscalls.h mn10300: switch to generic fork/vfork/clone h8300: switch to generic fork/vfork/clone tile: switch to generic clone() ...

These are parity protected only, so only error reporting. o Second level cache - ECC protected, provides SECDED. o Memory: ECC / SECDEC if used with suitable DRAM modules. The driver will will only initialize if ECC is enabled on a system so is safe to run on non-ECC memory. o PCI: Parity error reporting Since it is very hard to test this sort of code the implementation is very conservative and uses polling where possible for now.

The problems are many-fold, from the driver not being informed about updated settings, to the driver not knowing what the intentions of the upper layers are. The first four patches tackle the serial_core layer, allowing it to provide the necessary information to drivers, and the remaining patches allow the OMAP serial driver to take advantage of this.

The controller on the docg4 has a "reliable" mode, where consecutive 2k pages are used in parallel.

This patch adds support for writing data in reliable mode, by way of a module parameter. Support for reading in this mode (as the IPL does) is not supported yet, but alternate (even-numbered) 2k pages written in reliable mode can be read normally (odd-numbered pages will contain junk and generate ecc errors).

2012-12-12OMAPDSS: DISPC: remove dispc fck usesTomi Valkeinen
The previous patch changes dispc to get the dispc fck rate from dss core driver. This was the only use of the dispc fck in dispc, and thus we can now remove the clock handling. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2012-12-12OMAPDSS: DISPC: get dss clock rate from dss driverTomi Valkeinen
Dispc currently gets dispc's fck with clk_get() and uses clk_get_rate() to get the rate for scaling calculations. This causes a problem with common clock framework, as omapdss uses the dispc functions inside a spinlock, and common clock framework uses a mutex in clk_get_rate(). Looking at the DSS clock tree, the above use of the dispc fck is not quite correct. The DSS_FCLK from PRCM goes to DSS core block, which has a mux to select the clock for DISPC from various options, so the current use of dispc fck bypasses that. Fortunately we never change the dispc clock mux for now. To fix the issue with clk_get_rate(), this patch caches the dss clock rate in dss.c when it is set. Dispc will then ask for the clock rate from dss. While this is not very elegant, it does fix the issue, and it's not totally wrong when considering that the dispc fck actually comes via dss. In the future we should probably look into common clock framework and see if that could be used to represent the DSS clock tree properly. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2012-12-11mm, memory-hotplug: dynamic configure movable memory and portion memoryLai Jiangshan
Add online_movable and online_kernel for logic memory hotplug. This is the dynamic version of "movablecore" & "kernelcore". We have the same reason to introduce it as to introduce "movablecore" & "kernelcore". It has the same motive as "movablecore" & "kernelcore", but it is dynamic/running-time: o We can configure memory as kernelcore or movablecore after boot. Userspace workload is increased, we need more hugepage, we can't use "online_movable" to add memory and allow the system use more THP(transparent-huge-page), vice-verse when kernel workload is increase. Also help for virtualization to dynamic configure host/guest's memory, to save/(reduce waste) memory. Memory capacity on Demand o When a new node is physically online after boot, we need to use "online_movable" or "online_kernel" to configure/portion it as we expected when we logic-online it. This configuration also helps for physically-memory-migrate. o all benefit as the same as existed "movablecore" & "kernelcore". o Preparing for movable-node, which is very important for power-saving, hardware partitioning and high-available-system(hardware fault management). (Note, we don't introduce movable-node here.) Action behavior: When a memoryblock/memorysection is onlined by "online_movable", the kernel will not have directly reference to the page of the memoryblock, thus we can remove that memory any time when needed. When it is online by "online_kernel", the kernel can use it. When it is online by "online", the zone type doesn't changed. Current constraints: Only the memoryblock which is adjacent to the ZONE_MOVABLE can be online from ZONE_NORMAL to ZONE_MOVABLE.

2012-12-11virtio_balloon: introduce migration primitives to balloon pagesRafael Aquini
Memory fragmentation introduced by ballooning might reduce significantly the number of 2MB contiguous memory blocks that can be used within a guest, thus imposing performance penalties associated with the reduced number of transparent huge pages that could be used by the guest workload. Besides making balloon pages movable at allocation time and introducing the necessary primitives to perform balloon page migration/compaction, this patch also introduces the following locking scheme, in order to enhance the syncronization methods for accessing elements of struct virtio_balloon, thus providing protection against concurrent access introduced by parallel memory migration threads. - balloon_lock (mutex) : synchronizes the access demand to elements of struct virtio_balloon and its queue operations; [yongjun_wei@trendmicro.com.cn: fix missing unlock on error in fill_balloon()] [akpm@linux-foundation.org: avoid having multiple return points in fill_balloon()] [akpm@linux-foundation.org: fix printk warning]Signed-off-by: Rafael Aquini <aquini@redhat.com> Acked-by: Michael S.

The reason is node's device struct does not have a release() function. So the patch registers node_device_release() to the device's release() function for suppressing the warning message. Additionally, the patch adds memset() to initialize a node struct into register_node(). Because the node struct is part of node_devices[] array and it cannot be freed by node_device_release().

Without doing post_cbfn, NAPI remains disabled and in cleanup we try to disable again causing endless wait. ifconfig process and other workers can thus get stuck. - Introducing start_stop_wait state for Rx.
