Hi Ingo,
Please consider pulling, next ones should be concentrating just on bug fixes, been busy with some, so some were left in the queue, flushing them now.

perf intel-pt/bts: Calculate cpumode for synthesized samples (2018-10-31 12:56:26 -0300)
perf/urgent improvements and fixes:
Fixes dealing with the removal of the fallback to looking up samples marked as userspace in the kernel maps, done recently:
For intel-pt, that was setting the synthesized header misc field as PERF_RECORD_MISC_USER, depending thus on the fallback to take place, now it sets as USER or KERNEL according to x86 specific knowledge. Also now it inserts the PERF_CONTEXT_{USER,KERNEL} into the PERF_SAMPLE_CALLCHAINs it synthesizes from hw traces (Adrian Hunter)
Similar fixes for the cs-etm ARM HW trace code, that used the Intel PT model as a starting point (Leo Yan)
For the "caller" callchain order, where the callchain returned by the kernel was simply reversed without taking into account the PERF_CONTEXT_{USER,KERNEL,etc} markers from where to define if an entry was for kernel or userspace, working just because the map lookup fallback was in place (David S. Miller)
Allow for selecting if 'overwrite' mode should be used in 'perf top' and make the default for it not to be used. This is due to problems with the current implementation where the pausing used ends up making 'perf top' miss PERF_RECORD_{MMAP,FORK,EXEC,etc} events, which with short lifetime threads workloads leads quickly to many "unknown" maps (and thus symbols) to appear in the UI. Workloads with long thread lifetimes and with few metadata events can still use --overwrite to take advantage of the overwrite mode (Arnaldo Carvalho de Melo)
Start 'perf top''s display thread earlier, so that the screen doesn't remain blank for too long at tool start (David S. Miller)
Don't clone maps from parent when synthesizing forks, to avoid the inevitable flurry of overlapping maps as we process the synthesized MMAP2 events that get delivered shortly thereafter. (David S. Miller)
Take pgoff into account when reporting elf to libdwfl, now the unwinding results are the same with elfutils's libdwfl and libunwind (Milian Wolff)
Update lotsa kernel ABI headers (Arnaldo Carvalho de Melo)
'perf trace' syscall arg beautification improvements to allow for handling args such as mount's 'flags', where maks have to be ignored before considering what is left, that, if only zeroes, is suppressed like other args without such masks (Arnaldo Carvalho de Melo)
Beautify mount's 'source' and 'flags' args (Arnaldo Carvalho de Melo)
Generate mmap's flags bit constants from linux/mman.h and all the arch specific mman.h files, so that no changes in the main 'perf trace' source files is required when new flags get added (Arnaldo Carvalho de Melo)
Consider syscall aliases, so that 'perf trace -e umount' works and we don't have to use 'umount2' (that works as well, just not required) (Arnaldo Carvalho de Melo)
