2017-04-06net_sched: check noop_qdisc before qdisc_hash_add()WANG Cong
Dmitry reported a crash when injecting faults in attach_one_default_qdisc() and dev->qdisc is still a noop_disc, the check before qdisc_hash_add() fails to catch it because it tests NULL. We should test against noop_qdisc since it is the default qdisc at this point.

2017-04-06net: ipv4: fix multipath RTM_GETROUTE behavior when iif is givenFlorian Larysch
inet_rtm_getroute synthesizes a skeletal ICMP skb, which is passed to ip_route_input when iif is given. If a multipath route is present for the designated destination, ip_multipath_icmp_hash ends up being called, which uses the source/destination addresses within the skb to calculate a hash. However, those are not set in the synthetic skb, causing it to return an arbitrary and incorrect result. Instead, use UDP, which gets no such special treatment.

2017-04-06sparc64: Fix kernel panic due to erroneous #ifdef surrounding pmd_write()Tom Hromatka
This commit moves sparc64's prototype of pmd_write() outside of the CONFIG_TRANSPARENT_HUGEPAGE ifdef. In 2013, commit a7b9403f0e6d ("sparc64: Encode huge PMDs using PTE encoding.") exposed a path where pmd_write() could be called without CONFIG_TRANSPARENT_HUGEPAGE defined. This can result in the panic below. The diff is awkward to read, but the changes are straightforward. pmd_write() was moved outside of #ifdef CONFIG_TRANSPARENT_HUGEPAGE. Also, __HAVE_ARCH_PMD_WRITE was defined. kernel BUG at include/asm-generic/pgtable.h:576! \|/ ____ \|/ "@'/ .. \`@" /_| \__/ |_\ \__U_/ oracle_8114_cdb(8114): Kernel bad sw trap 5 [#1] CPU: 120 PID: 8114 Comm: oracle_8114_cdb Not tainted 4.1.12-61.7.1.el6uek.rc1.sparc64 #1 task: fff8400700a24d60 ti: fff8400700bc4000 task.ti: fff8400700bc4000 TSTATE: 0000004411e01607 TPC: 00000000004609f8 TNPC: 00000000004609fc Y: 00000005 Not tainted TPC: <gup_huge_pmd+0x198/0x1e0> g0: 000000000001c000 g1: 0000000000ef3954 g2: 0000000000000000 g3: 0000000000000001 g4: fff8400700a24d60 g5: fff8001fa5c10000 g6: fff8400700bc4000 g7: 0000000000000720 o0: 0000000000bc5058 o1: 0000000000000240 o2: 0000000000006000 o3: 0000000000001c00 o4: 0000000000000000 o5: 0000048000080000 sp: fff8400700bc6ab1 ret_pc: 00000000004609f0 RPC: <gup_huge_pmd+0x190/0x1e0> l0: fff8400700bc74fc l1: 0000000000020000 l2: 0000000000002000 l3: 0000000000000000 l4: fff8001f93250950 l5: 000000000113f800 l6: 0000000000000004 l7: 0000000000000000 i0: fff8400700ca46a0 i1: bd0000085e800453 i2: 000000026a0c4000 i3: 000000026a0c6000 i4: 0000000000000001 i5: fff800070c958de8 i6: fff8400700bc6b61 i7: 0000000000460dd0 I7: <gup_pud_range+0x170/0x1a0> Call Trace: [0000000000460dd0] gup_pud_range+0x170/0x1a0 [0000000000460e84] get_user_pages_fast+0x84/0x120 [00000000006f5a18] iov_iter_get_pages+0x98/0x240 [00000000005fa744] do_direct_IO+0xf64/0x1e00 [00000000005fbbc0] __blockdev_direct_IO+0x360/0x15a0 [00000000101f74fc] ext4_ind_direct_IO+0xdc/0x400 [ext4] [00000000101af690] ext4_ext_direct_IO+0x1d0/0x2c0 [ext4] [00000000101af86c] ext4_direct_IO+0xec/0x220 [ext4] [0000000000553bd4] generic_file_read_iter+0x114/0x140 [00000000005bdc2c] __vfs_read+0xac/0x100 [00000000005bf254] vfs_read+0x54/0x100 [00000000005bf368] SyS_pread64+0x68/0x80 Signed-off-by: Tom Hromatka <tom.hromatka@oracle.com> Signed-off-by: David S.

2017-04-06pwm: rockchip: State of PWM clock should synchronize with PWM enabled stateDavid Wu
If the PWM was not enabled at U-Boot loader, PWM could not work for clock always disabled at PWM driver. The PWM clock is enabled at beginning of pwm_apply(), but disabled at end of pwm_apply(). If the PWM was enabled at U-Boot loader, PWM clock is always enabled unless closed by ATF. The pwm-backlight might turn off the power at early suspend, should disable PWM clock for saving power consume. It is important to provide opportunity to enable/disable clock at PWM driver, the PWM consumer should ensure correct order to call PWM enable and disable, and PWM driver ensure state of PWM clock synchronized with PWM enabled state.

2017-04-06pwm: lpss: Set enable-bit before waiting for update-bit to go lowHans de Goede
At least on cherrytrail, the update bit will never go low when the enabled bit is not set. This causes the backlight on my cube iwork8 air tablet to never turn on again after being turned off because in the pwm_lpss_apply enable path pwm_lpss_update will fail causing an error exit and the enable-bit to never get set. Any following pwm_lpss_apply calls will fail the pwm_lpss_is_updating check. Since the docs say that the update bit should be set before the enable-bit, split pwm_lpss_update into setting the update-bit and pwm_lpss_wait_for_update, and move the pwm_lpss_wait_for_update call in the enable path to after setting the enable-bit.
