Paolo 'Blaisorblade' Giarrusso 37fce857be [PATCH] uml: split CONFIG_FRAME_POINTER from DEBUG_INFO
Until now, FRAME_POINTER was set = DEBUG_INFO for UML.  Change it to be the
default way, so that it can be enabled alone (for instance to get better
backtraces on crashes).  The call-trace dumper which uses the frame pointer is
not yet in, I'm going to introduce it in a separate patch.

config PT_PROXY
bool "Enable ptrace proxy"
depends on XTERM_CHAN && DEBUG_INFO && MODE_TT
help
This option enables a debugging interface which allows gdb to debug
the kernel without needing to actually attach to kernel threads.
If you want to do kernel debugging, say Y here; otherwise say N.
config GPROF
bool "Enable gprof support"
depends on DEBUG_INFO && MODE_SKAS && !MODE_TT
help
This allows profiling of a User-Mode Linux kernel with the gprof
utility.
See <http://user-mode-linux.sourceforge.net/gprof.html> for more
details.
If you're involved in UML kernel development and want to use gprof,
say Y. If you're unsure, say N.
config GCOV
bool "Enable gcov support"
depends on DEBUG_INFO && MODE_SKAS
help
This option allows developers to retrieve coverage data from a UML
session.
See <http://user-mode-linux.sourceforge.net/gprof.html> for more
details.
If you're involved in UML kernel development and want to use gcov,
say Y. If you're unsure, say N.
config SYSCALL_DEBUG
bool "Enable system call debugging"
default N
depends on DEBUG_INFO
help
This adds some system debugging to UML, including keeping a ring buffer
with recent system calls and some global and per-task statistics.
If unsure, say N
