Mac Mini 7,1 model with CS4208 codec reports the headphone jack
detection wrongly in an inverted way. Moreover, the advertised pins
for the audio input and SPDIF output have actually no jack detection.
This patch addresses these issues. The inv_jack_detect flag is set
for fixing the headphone jack detection, and the pin configs for audio
input and SPDIF output are marked as non-detectable.

For CONFIG_KALLSYMS, we keep two symbol tables and two string tables.
There's one full copy, marked SHF_ALLOC and laid out at the end of the
module's init section. There's also a cut-down version that only
contains core symbols and strings, and lives in the module's core
section.
After module init (and before we free the module memory), we switch
the mod->symtab, mod->num_symtab and mod->strtab to point to the core
versions. We do this under the module_mutex.
However, kallsyms doesn't take the module_mutex: it uses
preempt_disable() and rcu tricks to walk through the modules, because
it's used in the oops path. It's also used in /proc/kallsyms.
There's nothing atomic about the change of these variables, so we can
get the old (larger!) num_symtab and the new symtab pointer; in fact
this is what I saw when trying to reproduce.
By grouping these variables together, we can use a
carefully-dereferenced pointer to ensure we always get one or the
other (the free of the module init section is already done in an RCU
callback, so that's safe). We allocate the init one at the end of the
module init section, and keep the core one inside the struct module
itself (it could also have been allocated at the end of the module
core, but that's probably overkill).

Commit f2411da746 ("driver-core: add driver module
asynchronous probe support") added async probe support,
in two forms:
* in-kernel driver specification annotation
* generic async_probe module parameter (modprobe foo async_probe)
To support the generic kernel parameter parse_args() was
extended via commit ecc8617053 ("module: add extra
argument for parse_params() callback") however commit
failed to f2411da746 failed to add the required argument.
This causes a crash then whenever async_probe generic
module parameter is used. This was overlooked when the
form in which in-kernel async probe support was reworked
a bit... Fix this as originally intended.

The only remaining caller of genpd_poweron() is conditionally compiled
based on CONFIG_PM_GENERIC_DOMAINS_OF, so we get a warning when that is
unset.
By moving the locking/unlocking of the genpd outside genpd_poweron(), thus
to the caller, genpd_poweron() becomes redundant.
Within this context let's then rename the wrapper function,
__genpd_poweron(), to genpd_poweron() as it will then be consistent with
its friend genpd_poweroff().
This change silence the warning about the unused function.

ALSA timer core framework has no sync point at stopping because it's
called inside the spinlock. Thus we need a sync point at close for
avoiding the stray timer task. This is simply done by implementing
the close callback just calling del_timer_sync(). (It's harmless to
call it unconditionally, as the core timer itself cares of the already

'perf probe' through debuginfo__find_probes() in util/probe-finder.c
checks for the functions' frame descriptions in either .eh_frame section
of an ELF or the .debug_frame.
The check is based on whether either one of these sections is present.
Depending on distro, toolchain defaults, architetcutre, build flags,
etc., CFI might be found in either .eh_frame and/or .debug_frame.
Sometimes, it may happen that, .eh_frame, even if present, may not be
complete and may miss some descriptions.
Therefore, to be sure, to find the CFI covering an address we will
always have to investigate both if available.
For e.g., in powerpc, this may happen:
$ gcc -g bin.c -o bin
$ objdump --dwarf ./bin
<1><145>: Abbrev Number: 7 (DW_TAG_subprogram)
<146> DW_AT_external : 1
<146> DW_AT_name : (indirect string, offset: 0x9e): main
<14a> DW_AT_decl_file : 1
<14b> DW_AT_decl_line : 39
<14c> DW_AT_prototyped : 1
<14c> DW_AT_type : <0x57>
<150> DW_AT_low_pc : 0x100007b8
If the .eh_frame and .debug_frame are checked for the same binary, we
will find that, .eh_frame (although present) doesn't contain a
description for "main" function.
But, .debug_frame has a description:
000000d8 00000024 00000000 FDE cie=00000000 pc=100007b8..10000838
DW_CFA_advance_loc: 16 to 100007c8
DW_CFA_def_cfa_offset: 144
DW_CFA_offset_extended_sf: r65 at cfa+16
...
Due to this (since, perf checks whether .eh_frame is present and goes on
searching for that address inside that frame), perf is unable to process
the probes:
# perf probe -x ./bin main
Failed to get call frame on 0x100007b8
Error: Failed to add events.
To avoid this issue, we need to check both the sections (.eh_frame and
.debug_frame), which is done in this patch.
Note that, we can always force everything into both .eh_frame and
.debug_frame by:
$ gcc bin.c -fasynchronous-unwind-tables -fno-dwarf2-cfi-asm -g -o bin

intel_pt_process_auxtrace_info() creates a pt->unknown_thread thread
that eventually needs to be freed by the last thread__put() on it, when
its refcount hits zero, which may happen in
intel_pt_process_auxtrace_info() error handling path and triggers the
following segfault, which would happen as well at intel_pt_free, when
tools using this intel_pt codebase frees up resources:
# perf record -I -e intel_pt/tsc=1,noretcomp=1/u /bin/ls
0 a anaconda-ks.cfg bin perf.data perf.data.old perf-f23-bringup.todo

Samples for 'instructions:u' event do not have IREGS attribute set. Cannot print 'iregs' field.
intel_pt_synth_events: failed to synthesize 'instructions' event type
Segmentation fault (core dumped)
#
The problem is: there's a union in 'struct thread' combines a list_head
and a rb_node. The standard life cycle of a thread is: init rb_node in
the constructor, insert it into machine->threads rbtree using rb_node,
move it to machine->dead_threads using list_head, clean in the last
thread__put: list_del_init(&thread->node).
In the above command, it clean a thread before adding it into list,
causes the above segfault.
Since pt->unknown_thread will never live in an rbtree, initialize its
list node so that when list_del_init() is done on it we don't segfault.
After this patch:

The range of set_memory_* is currently restricted to the module address
range because of difficulties in breaking down larger block sizes.
vmalloc maps PAGE_SIZE pages so it is safe to use as well. Update the
function ranges and add a comment explaining why the range is restricted
the way it is.

The change from cur_tp to the function
minstrel_get_tp_avg/minstrel_ht_get_tp_avg changed the unit used for the
current throughput. For example in minstrel_ht the correct
conversion between them would be:
mrs->cur_tp / 10 == minstrel_ht_get_tp_avg(..).
This factor 10 must also be included in the calculation of
minstrel_get_expected_throughput and minstrel_ht_get_expected_throughput to
return values with the unit [Kbps] instead of [10Kbps]. Otherwise routing
algorithms like B.A.T.M.A.N. V will make incorrect decision based on these
values. Its kernel based implementation expects expected_throughput always
to have the unit [Kbps] and not sometimes [10Kbps] and sometimes [Kbps].
The same requirement has iw or olsrdv2's nl80211 based statistics module
which retrieve the same data via NL80211_STA_INFO_TX_BITRATE.

pll_u can be either controlled by software or hardware and this is
selected via the OVERRIDE bit in the pll_u base register. In the function
tegra210_pll_init(), the OVERRIDE bit for pll_u is cleared, which selects
hardware control of the pll. However, at the same time the pll_u clocks
are populated in the init_table for tegra210 and so software will try to
configure the pll_u if it is not already configured and hence, the above
warning is seen when the pll fails to lock. Remove the pll_u clocks from
the init_table so that software does not try to configure this pll on
boot.

The EMC clock sources for Tegra210 currently incorrectly include pll_c2
and pll_c3. However, both of these should have been pll_mb as shown in
the TRM. If Tegra210 happens to be configured such that the pll_mb is the
default clock for the EMC, as configured by the bootloader, then this will
cause a system hang on boot. This is because the kernel will disable the
pll_mb when disabling unused clock as it appears to be unused when it is
not.
Also add the additional pll_p clock source for the EMC.
