2017-08-28perf c2c: Fix remote HITM detection for SkylakeJiri Olsa
Skylake introduced new mem_remote bit in union perf_mem_data_src [1]. It applies to any other memory level to express Remote unknown level, as is reported by Skylake. Adding this extra check to c2c_decode_stats to properly decode remote HITMs on Skylake.

2017-08-28perf tools: Fix static build with newer toolchainsJiri Olsa
We can't pass --dynamic-list list into static build anymore, because compilers starts to scream about that. Fedora 26 started to fail build with following error: $ make LDFLAGS=-static ... /usr/bin/ld: dynamic STT_GNU_IFUNC symbol `strcmp' with pointer equality in `/usr/lib/gcc/x86_64-redhat-linux/7/../../../../lib64/libc.a(strcmp.o +)' can not be used when making an executable; recompile with -fPIE and relink with -pie There's no sense for --dynamic-list in static build, because there's no .dynsym table in static binary. Consequently the traceevent plugins have never worked with static build, but it was quietly passed by. To fix this in future I think we should add support to compile plugins within the perf binary directly for static build.

2017-08-28dm mpath: do not lock up a CPU with requeuing activityBart Van Assche
When using the block layer in single queue mode, get_request() returns ERR_PTR(-EAGAIN) if the queue is dying and the REQ_NOWAIT flag has been passed to get_request(). Avoid that the kernel reports soft lockup complaints in this case due to continuous requeuing activity.

2017-08-28dm: fix printk() rate limiting codeBart Van Assche
Using the same rate limiting state for different kinds of messages is wrong because this can cause a high frequency message to suppress a report of a low frequency message. Hence use a unique rate limiting state per message type.

2017-08-28dm mpath: retry BLK_STS_RESOURCE errorsBart Van Assche
Retry requests instead of failing them if an out-of-memory error occurs or the block driver below dm-mpath is busy. This restores the v4.12 behavior of noretry_error(), namely that -ENOMEM results in a retry.

In commit 1aefc75b2449 ("cpufreq: stats: Make the stats code non-modular"), the CPU_FREQ_STAT code was made non-modular. Our defconfig still said =m though, which meant we no longer got the code at all. Switch the defconfig to =y. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

In commit d92d9c3a1448 ("drm: hide legacy drivers with CONFIG_DRM_LEGACY") CONFIG_DRM_RADEON was moved behind CONFIG_DRM_LEGACY meaning it stopped being enabled by ppc6xx_defconfig. Although no one has noticed, given this is basically a legacy platform, it seems anyone who is using it probably still wants this driver. So turn it back on for now.

In commit 73d8ef76006b ("Input: mousedev - stop offering PS/2 to userspace by default") the symbol INPUT_MOUSEDEV went from being 'default y' to 'default n' (implied). That means we no longer need to explicitly disable it in our defconfigs. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

2017-08-28powerpc/configs: Add CONFIG_RAS now required for CONFIG_EDACMichael Ellerman
In commit e3c4ff6d8c94 ("EDAC: Remove EDAC_MM_EDAC") CONFIG_EDAC grew a dependency on CONFIG_RAS. Some of our defconfigs don't have the latter, which means we lose CONFIG_EDAC, so add CONFIG_RAS to fix that. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

2017-08-28powerpc/configs: Drop no longer needed PCI_MSI on powernvMichael Ellerman

In commit 6b0b7551428e ("perf/core: Rename CONFIG_[UK]PROBE_EVENT to CONFIG_[UK]PROBE_EVENTS") it was renamed to CONFIG_UPROBE_EVENTS. Additionally it's default y, and we have the prerequisites enabled, so we don't need it in our defconfigs. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

In commit a85406afeb3e ("netfilter: conntrack: built-in support for SCTP"), NF_CT_PROTO_SCTP switched from tristate to bool and became default y. Similarly in commit 9b91c96c5d1f ("netfilter: conntrack: built-in support for UDPlite"), NF_CT_PROTO_UDPLITE switched from tristate to bool and became default y. We had a few configs which set them to =m, which is no longer valid. We don't need to change them to =y because both symbols are default y and are enabled automatically based on the other symbols in the affected defconfigs.

In commit 961518259b3b ("rcu: Enable RCU tracepoints by default to aid in debugging"), CONFIG_RCU_TRACE was made default y (if CONFIG_TREE_RCU=y, which it is for some of our configs). That in turn causes CONFIG_TREE_RCU_TRACE to be enabled, which selects CONFIG_DEBUG_FS. The end result is that CONFIG_DEBUG_FS is forced on, meaning we don't have to enable it in some of our configs.
