Currently the PROMPT variable could be abused to provoke the printf()
machinery to read outside the current stack frame. Normally this
doesn't matter becaues md is already a much better tool for reading
from memory.
However the md command can be disabled by not setting KDB_ENABLE_MEM_READ.
Let's also prevent PROMPT from being modified in these circumstances.
Whilst adding a comment to help future code reviewers we also remove
the #ifdef where PROMPT in consumed. There is no problem passing an
unused (0) to snprintf when !CONFIG_SMP.

Currently the code to manage the kdb history buffer uses strncpy() to
copy strings to/and from the history and exhibits the classic "but
nobody ever told me that strncpy() doesn't always terminate strings"
bug. Modern gcc compilers recognise this bug and issue a warning.
In reality these calls will only abridge the copied string if kdb_read()
has *already* overflowed the command buffer. Thus the use of counted
copies here is only used to reduce the secondary effects of a bug
elsewhere in the code.
Therefore transitioning these calls into strscpy() (without checking
the return code) is appropriate.

Alan Stern points out that the WARN_ON() check in device_prepare()
is racy (because the PM-runtime API can be disabled briefly for any
device at any time and system suspend can start at any time too) and
the pm_runtime_suspended() check in the computation of the
direct_complete flag value is redundant (because it will be
repeated later anyway).
Drop both these checks accordingly.

Declaring setjmp()/longjmp() as taking longs makes the signature
non-standard, and makes clang complain. In the past, this has been
worked around by adding -ffreestanding to the compile flags.
The implementation looks like it only ever propagates the value
(in longjmp) or sets it to 1 (in setjmp), and we only call longjmp
with integer parameters.
This allows removing -ffreestanding from the compilation flags.

GCC v8 defaults to enabling -fasynchronous-unwind-tables due to
https://gcc.gnu.org/r259298, which results in .eh_frame section being
generated. This results in additional disk usage by the build, as well
as the kernel modules. Since the kernel has no use for this, this
section is discarded.
Add -fno-asynchronous-unwind-tables to KBUILD_CFLAGS to suppress
generation of .eh_frame section. Note that our VDSOs need .eh_frame, but
are not affected by this change since our VDSO code are all in assembly.

We added a usage of try-run to pmu/ebb/Makefile to detect if the
toolchain supported the -no-pie option.
This fails if we build out-of-tree and the source tree is not
writable, as try-run tries to write its temporary files to the current
directory. That leads to the -no-pie option being silently dropped,
which leads to broken executables with some toolchains.
If we remove the redirect to /dev/null in try-run, we see the error:
make[3]: Entering directory '/linux/tools/testing/selftests/powerpc/pmu/ebb'
/usr/bin/ld: cannot open output file .54.tmp: Read-only file system
collect2: error: ld returned 1 exit status
make[3]: Nothing to be done for 'all'.
And looking with strace we see it's trying to use a file that's in the
source tree:
lstat("/linux/tools/testing/selftests/powerpc/pmu/ebb/.54.tmp", 0x7ffffc0f83c8)
We can fix it by setting TMPOUT to point to the $(OUTPUT) directory,
and we can verify with strace it's now trying to write to the output
directory:
lstat("/output/kselftest/powerpc/pmu/ebb/.54.tmp", 0x7fffd1bf6bf8)
And also see that the -no-pie option is now correctly detected.
