This has a different model than the 'thread' and 'map' struct lifetimes:
there is not a definitive "don't use this DSO anymore" event, i.e. we may
get many 'struct map' holding references to the '/usr/lib64/libc-2.20.so'
DSO but then at some point some DSO may have no references but we still
don't want to straight away release its resources, because "soon" we may
get a new 'struct map' that needs it and we want to reuse its symtab or
other resources.
So we need some way to garbage collect it when crossing some memory
usage threshold, which is left for anoter patch, for now it is
sufficient to release it when calling dsos__exit(), i.e. when deleting
the whole list as part of deleting the 'struct machine' containing it,
which will leave only referenced objects being used.

To allow concurrent access, next step: refcount struct dso instances, so
that we can ditch unused them when the last map pointing to it goes

Calling the function 'machine__new_module' implies a new 'module' will
be allocated, when in fact what is returned is a 'struct map' instance,
that not necessarily will be instantiated, as if one already exists with
the given module name, it will be returned instead.
So be consistent with other "find and if not there, create" like
functions, like machine__findnew_thread, machine__findnew_dso, etc, and
rename it to machine__findnew_module_map(), that in turn will call
machine__findnew_module_dso().

Traceevent plugins need dynamic symbols exported from libtraceevent.a,
otherwise a dlopen error will occur during plugins loading.
This patch uses dynamic-list-file to export dynamic symbols which will
be used in plugins to perf executable.
The problem is covered up if feature-libpython is enabled, because
PYTHON_EMBED_LDOPTS contains '-Xlinker --export-dynamic' which adds all
symbols to the dynamic symbol table. So we should reproduce the problem
by setting NO_LIBPYTHON=1.

are for sure 14e4:4321 PCI devices with BCM4321 (N-PHY) chipset, they
can be found in routers, e.g. Netgear WNR834Bv2. However, according to
Broadcom public sources 0x4321 is also used for 5 GHz BCM4306 (G-PHY).
It's unsure if they meant PCI device id, or "virtual" id (from SPROM).
To distinguish these devices lets check PHY type (G vs. N).

like: devpath0=pcie/1/4/ and entries like 0:foo=bar 0:baz=qux etc.
Unfortunately there are also a bit older devices using different way of
defining prefixes, e.g. SmartRG SR400ac (2 x BCM43602) with entries:
devpath0=pci/1/1/
devpath1=pci/2/1

So, I'm told this problem exists in the world:

I'm not really sure how it's okay that we have things in asm-generic on
some platforms but not others - is having it the same everywhere not the
whole point of asm-generic?
That said, ia64 doesn't have early_ioremap.h . So instead, since it's
difficult to imagine new IA64 machines with UEFI 2.5, just don't build
this code there.
To me this looks like a workaround - doing something like:
generic-y += early_ioremap.h
in arch/ia64/include/asm/Kbuild would appear to be more correct, but
ia64 has its own early_memremap() decl in arch/ia64/include/asm/io.h ,
and it's a macro. So adding the above /and/ requiring that asm/io.h be
included /after/ asm/early_ioremap.h in all cases would fix it, but
that's pretty ugly as well. Since I'm not going to spend the rest of my
life rectifying ia64 headers vs "generic" headers that aren't generic,
it's much simpler to just not build there.
Note that I've only actually tried to build this patch on x86_64, but
esrt.o still gets built there, and that would seem to demonstrate that
the conditional building is working correctly at all the places the code
built before. I no longer have any ia64 machines handy to test that the
exclusion actually works there.
