With the H2 and H3 board support removed from the driver, there
are actually no other users, so the entire driver can go away.

After the removal of the unused board files, I went through the
omap1 code to look for code that no longer has any callers
and remove that.

In particular, support for the omap7xx/omap8xx family is now
completely unused, so I'm only leaving omap15xx/omap16xx/omap59xx.

While compile-testing randconfig builds for the upcoming boardfile
removal, I noticed that an earlier patch of mine was completely
broken, and the introduction of CONFIG_ARCH_OMAP1_ANY only replaced
one set of build failures with another one, now resulting in
link failures like

ld: drivers/video/fbdev/omap/omapfb_main.o: in function `omapfb_do_probe':
drivers/video/fbdev/omap/omapfb_main.c:1703: undefined reference to `omap_set_dma_priority'

drivers/usb/gadget/udc/omap_udc.c:820: undefined reference to `omap_get_dma_active_status'

I tried reworking it, but the resulting patch ended up much bigger than
simply avoiding the original problem of unused-function warnings like

arch/arm/mach-omap1/mcbsp.c:76:30: error: unused variable 'omap1_mcbsp_ops' [-Werror,-Wunused-variable]

As a result, revert the previous fix, and rearrange the code that
produces warnings to hide them. For mcbsp, the #ifdef check can
simply be removed as the cpu_is_omapxxx() checks already achieve
the same result, while in the io.c the easiest solution appears to
be to merge the common map bits into each soc specific portion.
This gets cleaned in a nicer way after omap7xx support gets dropped,
as the remaining SoCs all have the exact same I/O map.

After commit b5aaaa66 ("ARM: pxa: add Kconfig dependencies for
ATAGS based boards"), the default PXA build no longer includes support
for the board files that are considered unused.

As a side-effect of this, the PXA310 and PXA320 support is not built
into the kernel any more, even though it should work in principle as
long as the symbols are enabled. As Robert points out, there are dts
files for zylonite and cm-x300, though those have not made it into the
mainline kernel.

Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown".  After a timer is set to this state, then it can no
longer be re-armed.

The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed.  It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.

This was created by using a coccinelle script and the following
commands:

    $ cat timer.cocci
    @@
    expression ptr, slab;
    identifier timer, rfield;
    @@
    (
    -       del_timer(&ptr->timer);
    +       timer_shutdown(&ptr->timer);
    |
    -       del_timer_sync(&ptr->timer);
    +       timer_shutdown_sync(&ptr->timer);
    )
      ... when strict

If mem-type is specified in the device tree
it would end up overriding the record_size
field instead of populating mem_type.

As record_size is currently parsed after the
improper assignment with default size 0 it
continued to work as expected regardless of the
value found in the device tree.

Simply changing the target field of the struct
is enough to get mem-type working as expected.

In commit 76d62f24 ("pstore: Switch pmsg_lock to an rt_mutex

However, its possible that CONFIG_RT_MUTEXES is not enabled,

When CFI_CLANG and KASAN are both enabled, LLVM doesn't generate a
CFI type hash for asan.module_ctor functions in translation units
where CFI is disabled, which leads to a CFI failure during boot when
do_ctors calls the affected constructors:

  CFI failure at do_basic_setup+0x64/0x90 (target:
  asan.module_ctor+0x0/0x28; expected type: 0xa540670c)

Specifically, this happens because CFI is disabled for
kernel/cfi.c. There's no reason to keep CFI disabled here anymore, so
fix the failure by not filtering out CC_FLAGS_CFI for the file.

Note that https://reviews.llvm.org/rG3b14862f0a96 fixed the issue
where LLVM didn't emit CFI type hashes for any sanitizer constructors,
but now type hashes are emitted correctly for TUs that use CFI.

 "perf tools fixes and improvements:

   - Don't stop building perf if python setuptools isn't installed, just
     disable the affected perf feature.

   - Remove explicit reference to python 2.x devel files, that warning
     is about python-devel, no matter what version, being unavailable
     and thus disabling the linking with libpython.

   - Don't use -Werror=switch-enum when building the python support that
     handles libtraceevent enumerations, as there is no good way to test
     if some specific enum entry is available with the libtraceevent
     installed on the system.

   - Introduce 'perf lock contention' --type-filter and --lock-filter,
     to filter by lock type and lock name:

        $ sudo ./perf lock record -a -- ./perf bench sched messaging

   - Fix splitting CC into compiler and options when checking if a
     option is present in clang to build the python binding, needed in
     systems such as yocto that set CC to, e.g.: "gcc --sysroot=/a/b/c".

   - Refresh metris and events for Intel systems: alderlake.
     alderlake-n, bonnell, broadwell, broadwellde, broadwellx,
     cascadelakex, elkhartlake, goldmont, goldmontplus, haswell,
     haswellx, icelake, icelakex, ivybridge, ivytown, jaketown,
     knightslanding, meteorlake, nehalemep, nehalemex, sandybridge,
     sapphirerapids, silvermont, skylake, skylakex, snowridgex,
     tigerlake, westmereep-dp, westmereep-sp, westmereex.

   - Add vendor events files (JSON) for AMD Zen 4, from sections
     2.1.15.4 "Core Performance Monitor Counters", 2.1.15.5 "L3 Cache
     Performance Monitor Counter"s and Section 7.1 "Fabric Performance
     Monitor Counter (PMC) Events" in the Processor Programming
     Reference (PPR) for AMD Family 19h Model 11h Revision B1
     processors.

     This constitutes events which capture op dispatch, execution and
     retirement, branch prediction, L1 and L2 cache activity, TLB
     activity, L3 cache activity and data bandwidth for various links
     and interfaces in the Data Fabric.

   - Also, from the same PPR are metrics taken from Section 2.1.15.2
     "Performance Measurement", including pipeline utilization, which
     are new to Zen 4 processors and useful for finding performance
     bottlenecks by analyzing activity at different stages of the
     pipeline.

   - Greatly improve the 'srcline', 'srcline_from', 'srcline_to' and
     'srcfile' sort keys performance by postponing calling the external
     addr2line utility to the collapse phase of histogram bucketing.

   - Fix 'perf test' "all PMU test" to skip parametrized events, that
     requires setting up and are not supported by this test.

   - Update tools/ copies of kernel headers: features,
     disabled-features, fscrypt.h, i915_drm.h, msr-index.h, power pc
     syscall table and kvm.h.

   - Add .DELETE_ON_ERROR special Makefile target to clean up partially
     updated files on error.

   - Simplify the mksyscalltbl script for arm64 by avoiding to run the
     host compiler to create the syscall table, do it all just with the
     shell script.

   - Further fixes to honour quiet mode (-q)"

Noticed this build failure on archlinux:base when building with clang:

  clang-14: error: optimization flag '-ffat-lto-objects' is not supported [-Werror,-Wignored-optimization-argument]

In tools/perf/util/setup.py we check if clang supports that option, but
since commit 3cad53a6 ("perf python: Account for multiple words
in CC") this got broken as in the common case where CC="clang":

  >>> cc="clang"
  >>> print(cc.split()[0])
  clang
  >>> option="-ffat-lto-objects"
  >>> print(str(cc.split()[1:]) + option)
  []-ffat-lto-objects
  >>>

And then the Popen will call clang with that bogus option name that in
turn will not produce the b"unknown argument" or b"is not supported"
that this function uses to detect if the option is not available and
thus later on clang will be called with an unknown/unsupported option.

Fix it by looking if really there are options in the provided CC
variable, and if so override 'cc' with the first token and append the
options to the 'option' variable.

Fixes: 3cad53a6 ("perf python: Account for multiple words in CC")
