2013-05-07ARC: Add support for nSIM OSCI System C modelMischa Jonker
This adds support for an ARC Virtual Platform. This platform is based on the System C standard promoted by the OSCI (Open System C Initiative) and uses nSIM to simulate the ARC CPU core itself. Users can build a virtual SoC by combining System C models of peripherals and CPU cores. Signed-off-by: Mischa Jonker <mjonker@synopsys.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2013-05-07ARC: [TB10x] Adapt device tree to new compatible stringChristian Ruppert
The original device tree was written using a slightly different implementation of the fixed-factor-clock device tree binding. The compatible string must be modified in order to be compatible with the new implementation.

2013-05-07ARC: Prepare interrupt code for external controllersChristian Ruppert
This patch adds some room for CPU-external interrupt controllers in the Linux interrupt space. Until now, only the 32 CPU internal interrupt lines were supported which does not allow for external interrupt controllers such as GPIO modules etc. Signed-off-by: Christian Ruppert <christian.ruppert@abilis.com> Signed-off-by: Pierrick Hascoet <pierrick.hascoet@abilis.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2013-05-07ARC: Allow embedded arc-intc to be properly placed in DT intc hierarchyVineet Gupta
arc-intc is initialized in arc common code as it is applicable to all platforms. However platforms with their own external intc still need to refer to it for correct DT interrupt tree hierarchy setup, e.g. static struct of_device_id __initdata tb10x_irq_ids[] = { { .compatible = "snps,arc700-intc", .data = dummy_init_irq }, { .compatible = "abilis,tb10x_ictl", .data = tb10x_init_irq }, {}, }; The fix is to use the generic irqchip framework to tie all irqchips in a special linker section and then call irqchip_init() which calls the DT of_irq_init() for all the intc in one go. That way the platform code need not be aware of arc-intc at all. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2013-05-07ARC: [cmdline] Don't overwrite u-boot provided bootargsVineet Gupta
The existing code was wrong on several counts: * uboot provided bootargs were copied into @boot_command_line, only to be over-written by setup_machine_fdt(), effectively lost * @cmdline_p returned by setup_arch() to start_kernel() didn't include the DT /bootargs Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

2013-05-07powerpc: Make hard_irq_disable() do the right thing vs. irq tracingBenjamin Herrenschmidt
If hard_irq_disable() is called while interrupts are already soft-disabled (which is the most common case) all is already well. However you can (and in some cases want) to call it while everything is enabled (to make sure you don't get a lazy even, for example before entry into KVM guests) and in this case we need to inform the irq tracer that the irqs are going off. We have to change the inline into a macro to avoid an include circular dependency hell hole. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2013-05-07ALSA: HDA: Fix Oops caused by dereference NULL pointerWang YanQing
The interrupt handler azx_interrupt will call azx_update_rirb, which may call snd_hda_queue_unsol_event, snd_hda_queue_unsol_event will dereference chip->bus pointer. The problem is we alloc chip->bus in azx_codec_create which will be called after we enable IRQ and enable unsolicited event in azx_probe. This will cause Oops due dereference NULL pointer.

2013-05-06NFSv3: match sec= flavor against server listWeston Andros Adamson
Older linux clients match the 'sec=' mount option flavor against the server's flavor list (if available) and return EPERM if the specified flavor or AUTH_NULL (which "matches" any flavor) is not found. Recent changes skip this step and allow the vfs mount even though no operations will succeed, creating a 'dud' mount. This patch reverts back to the old behavior of matching specified flavors against the server list and also returns EPERM when no sec= is specified and none of the flavors returned by the server are supported by the client. Example of behavior change: the server's /etc/exports: /export/krb5 *(sec=krb5,rw,no_root_squash) old client behavior: $ uname -a Linux one.apikia.fake 3.8.8-202.fc18.x86_64 #1 SMP Wed Apr 17 23:25:17 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux $ sudo mount -v -o sec=sys,vers=3 zero:/export/krb5 /mnt mount.nfs: timeout set for Sun May 5 17:32:04 2013 mount.nfs: trying text-based options 'sec=sys,vers=3,addr=192.168.100.10' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 192.168.100.10 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 192.168.100.10 prog 100005 vers 3 prot UDP port 20048 mount.nfs: mount(2): Permission denied mount.nfs: access denied by server while mounting zero:/export/krb5 recently changed behavior: $ uname -a Linux one.apikia.fake 3.9.0-testing+ #2 SMP Fri May 3 20:29:32 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux $ sudo mount -v -o sec=sys,vers=3 zero:/export/krb5 /mnt mount.nfs: timeout set for Sun May 5 17:37:17 2013 mount.nfs: trying text-based options 'sec=sys,vers=3,addr=192.168.100.10' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 192.168.100.10 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 192.168.100.10 prog 100005 vers 3 prot UDP port 20048 $ ls /mnt ls: cannot open directory /mnt: Permission denied $ sudo ls /mnt ls: cannot open directory /mnt: Permission denied $ sudo df /mnt df: ‘/mnt’: Permission denied df: no file systems processed $ sudo umount /mnt $ Signed-off-by: Weston Andros Adamson <dros@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2013-05-06parisc: fix partly 16/64k PAGE_SIZE bootHelge Deller
This patch fixes partly PAGE_SIZEs of 16K or 64K by adjusting the assembler PTE lookup code and the assembler TEMPALIAS code. Furthermore some data alignments for PAGE_SIZE have been limited to 4K (or less) to not waste too much memory with greater page sizes. As a side note, the palo loader can (currently) only handle up to 10 ELF segments which is fixed with tighter aligning as well. My testings indicated that the ldci command in the sba iommu coding needed adjustment by the PAGE_SHIFT value and that the I/O PDIR Page size was only set to 4K for my machine (C3000). All this fixes partly the boot, but there are still quite some caching problems left. Examples are e.g. the symbios logic driver which is failing: sym0: <896> rev 0x7 at pci 0000:00:0f.0 irq 69 sym0: PA-RISC Firmware, ID 7, Fast-40, SE, parity checking CACHE TEST FAILED: DMA error (dstat=0x81).sym0: CACHE INCORRECTLY CONFIGURED. and the tulip network driver which doesn't seem to work correctly either: Sending BOOTP requests .net eth0: Setting full-duplex based on MII#1 link partner capability of 05e1 ..... timed out! Beside those kernel fixes glibc will need fixes too to be able to handle >4K page sizes. Signed-off-by: Helge Deller <deller@gmx.de>

Most of it is culmination of Alex's work to implement RBD image layering, which is now complete (yay!). There is also some work from Yan to fix i_mutex behavior surrounding writes in cephfs, a sync write fix, a fix for RBD images that get resized while they are mapped, and a few patches from me that resolve annoying auth warnings and fix several bugs in the ceph auth code." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client: (254 commits) rbd: fix image request leak on parent read libceph: use slab cache for osd client requests libceph: allocate ceph message data with a slab allocator libceph: allocate ceph messages with a slab allocator rbd: allocate image object names with a slab allocator rbd: allocate object requests with a slab allocator rbd: allocate name separate from obj_request rbd: allocate image requests with a slab allocator rbd: use binary search for snapshot lookup rbd: clear EXISTS flag if mapped snapshot disappears rbd: kill off the snapshot list rbd: define rbd_snap_size() and rbd_snap_features() rbd: use snap_id not index to look up snap info rbd: look up snapshot name in names buffer rbd: drop obj_request->version rbd: drop rbd_obj_method_sync() version parameter rbd: more version parameter removal rbd: get rid of some version parameters rbd: stop tracking header object version rbd: snap names are pointer to constant data ...

2013-05-06autofs - remove autofs dentry mount checkDavid Jeffery
When checking if an autofs mount point is busy it isn't sufficient to only check if it's a mount point. For example, if the mount of an offset mountpoint in a tree is denied for this host by its export and the dentry becomes a process working directory the check incorrectly returns the mount as not in use at expire. This can happen since the default when mounting within a tree is nostrict, which means ingnore mount fails on mounts within the tree and continue. The nostrict option is meant to allow mounting in this case.
