perf/core improvements and fixes
User visible: o Prep patches to support 'perf kvm stat' on s390 (Alexander Yarygin) o Add pagefault statistics in 'trace' (Stanislav Fomichev) o Add header for columns in 'top' and 'report' TUI browsers (Jiri Olsa) o Add pagefault statistics in 'trace' (Stanislav Fomichev) Build fixes: Fix build on 32-bit systems (Arnaldo Carvalho de Melo) Cleanups: o Convert open coded equivalents to asprintf() (Andy Shevchenko) Plumbing: o Allow reserving a row for header purposes in the hists browser (Arnaldo Carvalho de Melo) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJTvEAcAAoJENZQFvNTUqpA/MgP/iv8Qfe464fpsqnUZCAHMEw5 CINVqTagB0xA5ga+UO9sMTuxY6ZEvd7C9eIsTBcuhxx84J7AHMuwaxFB6KnmaDGf 5KyP81nP/lafKO06eiD/ERxi/Y1X6UjB9x5dYtItMVL+uyFRmBzyfFFfjAzju/rR RiC3HdnTm0xiFXKAEQShhVcLb1xpnm49amiFLgz+zK/WTWK1Mo2/jMuEIGFy9F8R zFuVbRuHFYmoFkNAlv5byHbGm+d2mwMZa7jc5hVbkFGb/SxZTMYANUTmYMFEZImU lOo4g6UwdZ/aEO/p/iqWV/mhhV8qTKzgoMhGR239xG/yA6MDqwDrkDKZZz4xHQJZ I5i6/xj3iesViSO8p7nYEZPq3VARPo+93x38snq+fMPTj/beSTlLcWcr7iP+L6EZ 5iJ9lWTLqohpi3Lvla2soqlpS8vwKNspsL6VRzBiGSmp4vLs3KGDCACjIaLA1D0u 4uCrDq68lwR8BT+sE+4AJ2q/7KRU1VM7RC7k9B27OiF8Cb2RXQQ5LpW8i2Er6spV DYfbBCi+Tkgn/Y0Vr9OqnvxvFRtYA1iD6pfWzsDjLovzVcdXwVEs5FtGzfl2A0vB ZriNg2ByudA/K6Yj0jbox7O+aJaYzvOBn9gHTZSuWfnOwOEX0SCDIV8lZaqVWem3 rzy3m/ArvTYyzzW4+W85 =tb1y -----END PGP SIGNATURE----- Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: User visible changes: o Prep patches to support 'perf kvm stat' on s390 (Alexander Yarygin) o Add pagefault statistics in 'trace' (Stanislav Fomichev) o Add header for columns in 'top' and 'report' TUI browsers (Jiri Olsa) o Add pagefault statistics in 'trace' (Stanislav Fomichev) Build fixes: o Fix build on 32-bit systems (Arnaldo Carvalho de Melo) Cleanups: o Convert open coded equivalents to asprintf() (Andy Shevchenko) Plumbing changes: o Allow reserving a row for header purposes in the hists browser (Arnaldo Carvalho de Melo) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org>
