'perf report --tui' exits with error when it finds a sample of zero
length symbol (i.e. addr == sym->start == sym->end). Actually these are
valid samples. Don't exit TUI and show report with such symbols.

If jump target is outside of function range, perf is not handling it
correctly. Especially when target address is lesser than function start
address, target offset will be negative. But, target address declared to
be unsigned, converts negative number into 2's complement. See
From: Ravi Bangoria
Architectures like PowerPC have jump instructions that includes a target
address as a second operand. For example, 'bne cr7,0xc00f6154'.
Add support for such instruction in perf annotate.

Added check for OPAL_WRONG_STATE error code returned from OPAL.
Currently Linux flashes "unexpected error" over console for this
error. This will avoid throwing such message and return I/O error

Currently, if the kernel is running on a POWER9 processor under a
hypervisor, it will try to use the radix MMU even though it doesn't
have the necessary code to use radix under a hypervisor (it doesn't
negotiate use of radix, and it doesn't do the H_REGISTER_PROC_TBL
hcall). The result is that the
