Some hardware (such as Dell laptops) signal a variety of events through
the i8042 controller, even if these don't map to keyboard events. Add
support for drivers to filter the i8042 event stream in order to respond
to these events and (if appropriate) block them from entering the input
stream.

We need to protect not only i8042 status and data register from concurrent

move release of i8042_lock in i8042_interrupt() a little bit further down.

Configurable via symbol_conf.sort_by_name, so that the cost of an
extra rb_node on all 'struct symbol' instances is not paid by tools
that only want to decode addresses.
How to use it:
symbol_conf.sort_by_name = true;
symbol_init(&symbol_conf);
struct map *map = map_groups__find_by_name(kmaps, MAP__VARIABLE, "[kernel.kallsyms]");
if (map == NULL) {
pr_err("couldn't find map!\n");
kernel_maps__fprintf(stdout);
} else {
struct symbol *sym = map__find_symbol_by_name(map, sym_filter, NULL);
if (sym == NULL)
pr_err("couldn't find symbol %s!\n", sym_filter);
else
pr_info("symbol %s: %#Lx-%#Lx \n", sym_filter, sym->start, sym->end);
}
Looking over the vmlinux/kallsyms is common enough that I'll add a
variable to the upcoming struct perf_session to avoid the need to
use map_groups__find_by_name to get the main vmlinux/kallsyms map.
The above example looks on the 'variable' symtab, but it is just
like that for the functions one.
Also the sort operation is done when we first use
map__find_symbol_by_name, in a lazy way.

So it works with both /proc/kallsyms and with ELF symtabs, either
the one on the vmlinux explicitely passed via --vmlinux or in one
in the vmlinux_path that matches the buildid for the running kernel
or the one found in the buildid header section in a perf.data file.

Using a struct thread instance just to hold the kernel space maps
(vmlinux + modules) is overkill and confuses people trying to
understand the perf symbols abstractions.
The kernel maps are really present in all threads, i.e. the kernel
is a library, not a separate thread.
So introduce the 'map_groups' abstraction and use it for the kernel
maps, now in the kmaps global variable.
It, in turn, will move, together with the threads list to the
perf_file abstraction, so that we can support multiple perf_file
instances, needed by perf diff.
