2019-05-02powerpc/book3e: drop BUG_ON() in map_kernel_page()Christophe Leroy
early_alloc_pgtable() never returns NULL as it panics on failure. This patch drops the three BUG_ON() which check the non nullity of early_alloc_pgtable() returned value. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

2019-05-02ice: Add missing PHY type to link settingsTony Nguyen
The PHY type ICE_PHY_TYPE_LOW_25G_AUI_C2C is missing from ice_get_settings_link_up() which is causing a warning message for unrecognized PHY. Add the PHY type to correctly set the settings and avoid the warning message.

2019-05-02ice: Add reg_idx variable in ice_q_vector structureBrett Creeley
Every time we want to re-enable interrupts and/or write to a register that requires an interrupt vector's hardware index we do the following: vsi->hw_base_vector + q_vector->v_idx This is a wasteful operation, especially in the hot path. Fix this by adding a u16 reg_idx member to the ice_q_vector structure and make the necessary changes to make this work.

2019-05-02ice: Remove runtime change of PFINT_OICR_ENA registerMd Fahad Iqbal Polash
Runtime change of PFINT_OICR_ENA register is unnecessary. The handlers should always clear the atomic bit for each task as they start, because it will make sure that any late interrupt will either 1) re-set the bit, or 2) be handled directly in the "already running" task handler.

2019-05-02ice: Fix issue when adding more than allowed VLANsAkeem G Abodunrin
This patch fixes issue with non trusted VFs being able to add more than permitted number of VLANs by adding a check in ice_vc_process_vlan_msg. Also don't return an error in this case as the VF does not need to know that it is not trusted. Also rework ice_vsi_kill_vlan to use the right types.

2019-05-02ice: Remove unnecessary wait when disabling/enabling Rx queuesBrett Creeley
In ice_vsi_ctrl_rx_rings() we are unnecessarily waiting for QRX_CTRL_QENA_REQ and QRX_CTRL_QENA_STAT to be the same value prior to disabling each Rx queue. There is no reason to do this so remove this wait loop as we already have a wait loop after disabling/enabling the Rx queue through the QRX_CTRL register to make sure it gets successfully disabled/enabled.

2019-05-02ice: Add ability to update rx-usecs-highBrett Creeley
Currently the driver allows rx-usecs-high values to be set, but when querying the device for rx-usecs-high the value does not stick. This is because it was not yet implemented.

2019-05-02ice: Validate ring existence and its q_vector per VSIMaciej Fijalkowski
When stopping Tx rings, we use 'i' as an ring array index for looking up whether the ice_ring exists and have assigned a q_vector. This checks rings only within a given TC and we need to go through every ring in VSI. Use 'q_idx' instead.

While we are at it, don't just pass the address of what happens to be the first member of structure to kmem_cache_free() - get_fuse_inode() is there for purpose and it gives the proper container_of() use.
