IB/mlx4: Avoid implicit enumerated type conversion

2019-11-24T07:23:05Z

[ Upstream commit b56511c15713ba6c7572e77a41f7ddba9c1053ec ] Clang warns when one enumerated type is implicitly converted to another. drivers/infiniband/hw/mlx4/mad.c:1811:41: warning: implicit conversion from enumeration type 'enum mlx4_ib_qp_flags' to different enumeration type 'enum ib_qp_create_flags' [-Wenum-conversion] qp_init_attr.init_attr.create_flags = MLX4_IB_SRIOV_TUNNEL_QP; ~ ^~~~~~~~~~~~~~~~~~~~~~~ drivers/infiniband/hw/mlx4/mad.c:1819:41: warning: implicit conversion from enumeration type 'enum mlx4_ib_qp_flags' to different enumeration type 'enum ib_qp_create_flags' [-Wenum-conversion] qp_init_attr.init_attr.create_flags = MLX4_IB_SRIOV_SQP; ~ ^~~~~~~~~~~~~~~~~ The type mlx4_ib_qp_flags explicitly provides supplemental values to the type ib_qp_create_flags. Make that clear to Clang by changing the create_flags type to u32. Reported-by: Nick Desaulniers Signed-off-by: Nathan Chancellor Signed-off-by: Jason Gunthorpe Signed-off-by: Sasha Levin

dmaengine: ep93xx: Return proper enum in ep93xx_dma_chan_direction

[ Upstream commit 9524d6b265f9b2b9a61fceb2ee2ce1c2a83e39ca ] Clang warns when implicitly converting from one enumerated type to another.

SUNRPC: Fix priority queue fairness

2019-11-24T07:22:52Z

[ Upstream commit f42f7c283078ce3c1e8368b140e270755b1ae313 ] Fix up the priority queue to not batch by owner, but by queue, so that we allow '1 << priority' elements to be dequeued before switching to the next priority queue. The owner field is still used to wake up requests in round robin order by owner to avoid single processes hogging the RPC layer by loading the queues.

fbdev: Ditch fb_edid_add_monspecs

EDAC: Raise the maximum number of memory controllers

[ Upstream commit 6b58859419554fb824e09cfdd73151a195473cbc ] We observe an oops in the skx_edac module during boot: EDAC MC0: Giving out device to module skx_edac controller Skylake Socket#0 IMC#0 EDAC MC1: Giving out device to module skx_edac controller Skylake Socket#0 IMC#1 EDAC MC2: Giving out device to module skx_edac controller Skylake Socket#1 IMC#0 ...

Raise the maximum number of memory controllers from 16 to 2 * MAX_NUMNODES (1024).

cpufeature: avoid warning when compiling with clang

2019-11-20T17:00:23Z

[ Upstream commit c785896b21dd8e156326ff660050b0074d3431df ] The table id (second) argument to MODULE_DEVICE_TABLE is often referenced otherwise. This is not the case for CPU features. This leads to warnings when building the kernel with Clang: arch/arm/crypto/aes-ce-glue.c:450:1: warning: variable 'cpu_feature_match_AES' is not needed and will not be emitted [-Wunneeded-internal-declaration] module_cpu_feature_match(AES, aes_init); ^ Avoid warnings by using __maybe_unused, similar to commit 1f318a8bafcf ("modules: mark __inittest/__exittest as __maybe_unused").

sched/debug: Use symbolic names for task state constants

2019-11-20T16:59:50Z

[ Upstream commit ff28915fd31ccafc0d38e6f84b66df280ed9e86a ] include/trace/events/sched.h includes (via ) and so knows about the TASK_* constants used to interpret .prev_state. So instead of duplicating the magic numbers make use of the defined macros to ease understanding the mapping from state bits to letters which isn't completely intuitive for an outsider.
