Every tracepoint creates two functions, the usual one 'trace_*()'
and the rcuidle one 'trace_*_rcuidle()'. Add regex for the
rcuidle variant so that we can jump to the tracepoints that use
rcuidle.

Before rpm release 4.1, in 2002, either the rpm command or the
rpmbuild command could be used in the rpm-pkg or binrpm-pkg targets,
and the Makefile chose the rpm command if the rpmbuild command wasn't
found.
After release 4.1, however, the rpm command could no longer be used in
place of the rpmbuild command. As the rpmbuild command is not
installed by default, this can lead to failures with the rpm-pkg and
binrpm-pkg targets:
rpm --define "_builddir ." --target \
x86_64 -bb ./binkernel.spec
rpm --target: unknown option
scripts/package/Makefile:60: recipe for target 'binrpm-pkg' failed
Change the Makefile to use rpmbuild unconditionally to avoid this.

When building a package with make deb-pkg (say, for arm), the dtb files are
not added to the package. Given that things are still evolving on arm, it
make sense to have them along with the kernel and modules.

If CONFIG_MODULE_SIG_ALL is set, then user expects that all modules are
automatically signed in the result package, as it's for rpm-pkg, binrpm-pkg,
tar, tar-*. For deb-pkg this is correct only if CONFIG_DEBUG_INFO
is NOT set. In that case deb-package contains signed modules.
But if CONFIG_DEBUG_INFO is set, builddeb creates separate package with
debug information. To do that, debug information from all modules
is copied into separate files by objcopy. And loadable kernel modules are
stripped afterwards. Stripping removes previously (during modules_install)
added signatures from loadable kernel modules. Therefore final deb-package
contains unsigned modules despite of set option CONFIG_MODULE_SIG_ALL.
This patch resigns all stripped modules if CONFIG_MODULE_SIG_ALL is set
to solve this problem.

Currently an allyesconfig build [gcc-4.9.1] can generate the following:
WARNING: vmlinux.o(.text.unlikely+0x3864): Section mismatch in
reference from the function cpumask_empty.constprop.3() to the
variable .init.data:nmi_ipi_mask
which comes from the cpumask_empty usage in arch/x86/kernel/nmi_selftest.c.
Normally we would not see a symbol entry for cpumask_empty since it is:
static inline bool cpumask_empty(const struct cpumask *srcp)
however in this case, the variant of the symbol gets emitted when GCC does
constant propagation optimization.
Fix things up so that any locally optimized constprop variants don't warn
when accessing variables that live in the __init sections.

Currently the match() function supports a leading * to match any
prefix and a trailing * to match any suffix. However there currently
is not a combination of both that can be used to target matches of
whole families of functions that share a common substring.
Here we expand the *foo and foo* match to also support *foo* with
the goal of targeting compiler generated symbol names that contain
strings like ".constprop." and ".isra."

As Guenter pointed out, we were never really calculating the extable entry
size because the pointer arithmetic was simply wrong. We want to check
we're handling the second relocation in __ex_table to infer an entry size,
but we were using (void*) pointers instead of Elf_Rel[a]* ones.
This fixes the problem by moving that check in the caller (since we can
deal with different types of relocations) and add is_second_extable_reloc()
to make the whole thing more readable.

As Guenter pointed out, we want to assert that extable_entry_size has been
discovered and not the other way around. Moreover, this sanity check is
only valid when we're not dealing with the first relocation in __ex_table,
since we have not discovered the extable entry size at that point.
This was leading to a divide-by-zero on some architectures and make the
build fail.
