2017-08-30objtool: Handle GCC stack pointer adjustment bugJosh Poimboeuf
Arnd Bergmann reported the following warning with GCC 7.1.1: fs/fs_pin.o: warning: objtool: pin_kill()+0x139: stack state mismatch: cfa1=7+88 cfa2=7+96 And the kbuild robot reported the following warnings with GCC 5.4.1: fs/fs_pin.o: warning: objtool: pin_kill()+0x182: return with modified stack frame fs/quota/dquot.o: warning: objtool: dquot_alloc_inode()+0x140: stack state mismatch: cfa1=7+120 cfa2=7+128 fs/quota/dquot.o: warning: objtool: dquot_free_inode()+0x11a: stack state mismatch: cfa1=7+112 cfa2=7+120 Those warnings are caused by an unusual GCC non-optimization where it uses an intermediate register to adjust the stack pointer. It does: lea 0x8(%rsp), %rcx ... mov %rcx, %rsp Instead of the obvious: add $0x8, %rsp It makes no sense to use an intermediate register, so I opened a GCC bug to track it: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81813 But it's not exactly a high-priority bug and it looks like we'll be stuck with this issue for a while. So for now we have to track register values when they're loaded with stack pointer offsets. This is kind of a big workaround for a tiny problem, but c'est la vie. I hope to eventually create a GCC plugin to implement a big chunk of objtool's functionality. Hopefully at that point we'll be able to remove of a lot of these GCC-isms from the objtool code.

When HEST is not present, the following superfluous message is printed to the kernel boot log - [ 3.460067] GHES: HEST is not enabled!

2017-08-30cpuidle: Eliminate the CPUIDLE_DRIVER_STATE_START symbolRafael J. Wysocki
On some architectures the first (index 0) idle state is a polling one and it doesn't really save energy, so there is the CPUIDLE_DRIVER_STATE_START symbol allowing some pieces of cpuidle code to avoid using that state. However, this makes the code rather hard to follow. It is better to explicitly avoid the polling state, so add a new cpuidle state flag CPUIDLE_FLAG_POLLING to mark it and make the relevant code check that flag for the first state instead of using the CPUIDLE_DRIVER_STATE_START symbol. In the ACPI processor driver that cannot always rely on the state flags (like before the states table has been set up) define a new internal symbol ACPI_IDLE_STATE_START equivalent to the CPUIDLE_DRIVER_STATE_START one and drop the latter.

2017-08-29neigh: increase queue_len_bytes to match wmem_defaultEric Dumazet
Florian reported UDP xmit drops that could be root caused to the too small neigh limit. Current limit is 64 KB, meaning that even a single UDP socket would hit it, since its default sk_sndbuf comes from net.core.wmem_default (~212992 bytes on 64bit arches). Once ARP/ND resolution is in progress, we should allow a little more packets to be queued, at least for one producer. Once neigh arp_queue is filled, a rogue socket should hit its sk_sndbuf limit and either block in sendmsg() or return -EAGAIN.

2017-08-29amd-xgbe: Interrupt summary bits are h/w version dependentTom Lendacky
There is a difference in the bit position of the normal interrupt summary enable (NIE) and abnormal interrupt summary enable (AIE) between revisions of the hardware. For older revisions the NIE and AIE bits are positions 16 and 15 respectively. For newer revisions the NIE and AIE bits are positions 15 and 14. The effect in changing the bit position is that newer hardware won't receive AIE interrupts in the current version of the driver. Specifically, the driver uses this interrupt to collect statistics on when a receive buffer unavailable event occurs and to restart the driver/device when a fatal bus error occurs. Update the driver to set the interrupt enable bit based on the reported version of the hardware. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S.

Note there is no code in this patchset that actually manipulates the NSH headers. That was sent to netdev by Yi Yang ("[PATCH net-next v6 0/3] openvswitch: add NSH support"). The aim of this series is to lay the groundwork and ease the implementation for him. In addition to openvswitch, the NSH support should be added to tc (flower to match, act_nsh to push/pop NSH headers). That will come later. There's currently no plan to support NSH by other means than those two.

2017-08-29tipc: permit bond slave as bearerParthasarathy Bhuvaragan
For a bond slave device as a tipc bearer, the dev represents the bond interface and orig_dev represents the slave in tipc_l2_rcv_msg(). Since we decode the tipc_ptr from bonding device (dev), we fail to find the bearer and thus tipc links are not established. In this commit, we register the tipc protocol callback per device and look for tipc bearer from both the devices.

Tariq Toukan says: ==================== mlx4 misc patches This patchset contains misc patches from the team to the mlx4 Core and Eth drivers. Patch 1 by Eran replaces large static allocations by dynamic ones. Patch 2 by Leon makes an explicit conversion and solves a smatch warning. In patch 3 I fix a misplaced brackets of the sizeof operation. Patch 4 by Moshe adds the ability to inform the FW regarding user mac updates.

2017-08-29net/mlx4: Add user mac FW update supportMoshe Shemesh
Adding support for updating the FW on new port mac, when port mac change is requested by the user. This info is required by the FW as OEM management tools require this info directly from the NIC FW. Check device capability bit to verify the FW supports user mac. If the FW does support it, use set_port command to notify the FW on the new mac. The feature is relevant only to PF port mac.

When changing the sizeof style usage in the patch cited below, one brackets misplacement was introduced. Here we fix it.

2017-08-29net/mlx4_core: Make explicit conversion to 64bit valueLeon Romanovsky
The "lg" variable is declared as int so in all places where this variable is used as a shift operand, the output will be int too. This produces the following smatch warning: drivers/net/ethernet/mellanox/mlx4/fw.c:1532 mlx4_map_cmd() warn: should '1 << lg' be a 64 bit type? Simple declaration of "1" to be "1ULL" will fix the issue.

Florian Fainelli says: ==================== Endian fixes for SYSTEMPORT/SF2/MDIO While trying an ARM BE kernel for kinks, the 3 drivers below started not working and the reasons why became pretty obvious because the register space remains LE (hardwired), except for Broadcom MIPS where it follows the CPU's native endian (let's call that a feature). ==================== Signed-off-by: David S.

2017-08-29net: phy: mdio-bcm-unimac: Use correct I/O accessorsFlorian Fainelli
The driver currently uses __raw_{read,write}l which works for all platforms supported: Broadcom MIPS LE/BE (native endian), ARM LE (native endian) but not ARM BE (registers are still LE). Switch to using the proper accessors for all platforms and explain why Broadcom MIPS BE is special here, in doing so, we introduce a couple of helper functions to abstract these differences.
