git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: - Fix an off-by-one bug in our alternative asm patching which leads to incorrectly patched code. This bug lay dormant for nearly 10 years but we finally hit it due to a recent change. - Fix lockups when running KVM guests on Power8 due to a missing check when a thread that's running KVM comes out of idle. - Fix an out-of-spec behaviour in the XIVE code (P9 interrupt controller). - Fix EEH handling of bridge MMIO windows. - Prevent crashes in our RFI fallback flush handler if firmware didn't tell us the size of the L1 cache (only seen on simulators).

2018-04-20usb: host: xhci-plat: Fix clock resource by adding a register clockGregory CLEMENT
On Armada 7K/8K we need to explicitly enable the register clock. This clock is optional because not all the SoCs using this IP need it but at least for Armada 7K/8K it is actually mandatory. The change was done at xhci-plat level and not at a xhci-mvebu.c because, it is expected that other SoC would have this kind of constraint. The binding documentation is updating accordingly.

On a system with 4-level page-tables there is no p4d, so the pud in the pgd should be mapped. The old code before commit fb43d6cb91ef already did that.

In some firmware images, the length of BNX_DIR_TYPE_PKG_LOG nvram type could be greater than the fixed buffer length of 4096 bytes allocated by the driver. This was causing HWRM_NVM_READ to copy more data to the buffer than the allocated size, causing general protection fault. Fix the issue by allocating the exact buffer length returned by HWRM_NVM_FIND_DIR_ENTRY, instead of 4096. Move the kzalloc() call into the bnxt_get_pkgver() function.

2018-04-19virtio_net: split out ctrl bufferMichael S. Tsirkin
When sending control commands, virtio net sets up several buffers for DMA. The buffers are all part of the net device which means it's actually allocated by kvmalloc so it's in theory (on extreme memory pressure) possible to get a vmalloc'ed buffer which on some platforms means we can't DMA there.

2018-04-19net: hns: Avoid action name truncationdann frazier
When longer interface names are used, the action names exposed in /proc/interrupts and /proc/irq/* maybe truncated.

2018-04-19fsnotify: Fix fsnotify_mark_connector raceRobert Kolchmeyer
fsnotify() acquires a reference to a fsnotify_mark_connector through the SRCU-protected pointer to_tell->i_fsnotify_marks. However, it appears that no precautions are taken in fsnotify_put_mark() to ensure that fsnotify() drops its reference to this fsnotify_mark_connector before assigning a value to its 'destroy_next' field. This can result in fsnotify_put_mark() assigning a value to a connector's 'destroy_next' field right before fsnotify() tries to traverse the linked list referenced by the connector's 'list' field. Since these two fields are members of the same union, this behavior results in a kernel panic. This issue is resolved by moving the connector's 'destroy_next' field into the object pointer union. This should work since the object pointer access is protected by both a spinlock and the value of the 'flags' field, and the 'flags' field is cleared while holding the spinlock in fsnotify_put_mark() before 'destroy_next' is updated. It shouldn't be possible for another thread to accidentally read from the object pointer after the 'destroy_next' field is updated. The offending behavior here is extremely unlikely; since fsnotify_put_mark() removes references to a connector (specifically, it ensures that the connector is unreachable from the inode it was formerly attached to) before updating its 'destroy_next' field, a sizeable chunk of code in fsnotify_put_mark() has to execute in the short window between when fsnotify() acquires the connector reference and saves the value of its 'list' field. On the HEAD kernel, I've only been able to reproduce this by inserting a udelay(1) in fsnotify(). However, I've been able to reproduce this issue without inserting a udelay(1) anywhere on older unmodified release kernels, so I believe it's worth fixing at HEAD.

vmxnet3_get_hdr_len() is used to calculate the header length which in turn is used to calculate the gso_size for skb. When rxvlan offload is disabled, vlan tag is present in the header and the function references ip header from sizeof(ethhdr) and leads to incorrect pointer reference.

2018-04-19ALSA: rawmidi: Fix missing input substream checks in compat ioctlsTakashi Iwai
Some rawmidi compat ioctls lack of the input substream checks (although they do check only for rfile->output). This many eventually lead to an Oops as NULL substream is passed to the rawmidi core functions. Fix it by adding the proper checks before each function call. The bug was spotted by syzkaller.

2018-04-19blkcg: init root blkcg_gq under lockJiang Biao
The initializing of q->root_blkg is currently outside of queue lock and rcu, so the blkg may be destroied before the initializing, which may cause dangling/null references. On the other side, the destroys of blkg are protected by queue lock or rcu. Put the initializing inside the queue lock and rcu to make it safer.

2018-04-19drm/msm: Fix possible null dereference on failure of get_pages()Ben Hutchings
Commit 62e3a3e342af changed get_pages() to initialise msm_gem_object::pages before trying to initialise msm_gem_object::sgt, so that put_pages() would properly clean up pages in the failure case. However, this means that put_pages() now needs to check that msm_gem_object::sgt is not null before trying to clean it up, and this check was only applied to part of the cleanup code. Move it all into the conditional block. (Strictly speaking we don't need to make the kfree() conditional, but since we can't avoid checking for null ourselves we may as well do so.)
