MF11 361020: Deprecate procfs-based process debugging.

2020-05-14T17:47:55Z

359047: Mark procfs-based process debugging as deprecated for FreeBSD 13. Attempting to use ioctls on /proc//mem to control a process will trigger warnings on the console. The include file will also now emit a compile-time warning when used from userland. 359054: Fix the workaround to ignore the #warning for GCC. clang and gcc use different warning flags for #warning preprocessor directives. For both 12 and 11, adjust the GCC warning flags to only be added in 4.7 and later since 4.2.1 does not support -Wno-cpp. For 11, add the needed warning suppression to procctl's build. procctl was removed in 12.0.

Share Linux errno table with libsysdecode.

2019-04-28T13:33:35Z

Share a single bsd-linux errno table across MD consumers Three copies of the linuxulator linux_sysvec.c contained identical BSD to Linux errno translation tables, and future work to support other architectures will also use the same table. Move the table to a common file to be used by all. Make it 'const int' to place it in .rodata. (Some existing Linux architectures use MD errno values, but x86 and Arm share the generic set.) This change should introduce no functional change; a followup will add missing errno values.

The vmresult table was missing most of the values apart from two due to extra "_" in the names we grep for. Add the "_" to the pattern. Reviewed by: jhb Sponsored by: iXsystems, Inc.
