cc2eca4309 iio: adc: ad7606: rename chan_scale to a more generic chan_info 
Non functional, renaming chan-related chan_scale structure to a more
generic chan_info, to host other chan specific settings, not just
scale-related.

Note that the driver does not need to take any actions if the supply

c5858465a6 iio: amplifiers: ada4250: use DMA-safe memory for regmap_bulk_read() 
Use DMA-safe memory instead of stack-allocated memory for the call to
regmap_bulk_read() in the ada4250_init() function as this could be used
directly by a SPI controller.

Also remove unnecessary use of get_unaligned_le16() and explicitly
include linux/types.h e.g. for __le16 while we are fixing this up.

Note this is DMA issue does not appear to be an actual bug due to
internals of the regmap SPI implementation.  However, for IIO we are
following guidance that we should not make that assumption.

Pull x86 fixes from Thomas Gleixner:
 "A small set of x86 fixes:

   - Cure IO bitmap inconsistencies

     A failed fork cleans up all resources of the newly created thread
     via exit_thread(). exit_thread() invokes io_bitmap_exit() which
     does the IO bitmap cleanups, which unfortunately assume that the
     cleanup is related to the current task, which is obviously bogus.

     Make it work correctly

   - A lockdep fix in the resctrl code removed the clearing of the
     command buffer in two places, which keeps stale error messages
     around. Bring them back.

   - Remove unused trace events"

69078520fd tools/power turbostat: Avoid probing the same perf counters 
For the RAPL package energy status counter, Intel and AMD share the same
perf_subsys and perf_name, but with different MSR addresses.

Both rapl_counter_arch_infos[0] and rapl_counter_arch_infos[1] are
introduced to describe this counter for different Vendors.

As a result, the perf counter is probed twice, and causes a failure in
in get_rapl_counters() because expected_read_size and actual_read_size
don't match.

Fix the problem by skipping the already probed counter.

Note, this is not a perfect fix. For example, if different
vendors/platforms use the same MSR value for different purpose, the code
can be fooled when it probes a rapl_counter_arch_infos[] entry that does
not belong to the running Vendor/Platform.

In a long run, better to put rapl_counter_arch_infos[] into the
platform_features so that this becomes Vendor/Platform specific.

ff3d019e98 tools/power turbostat: Allow probing RAPL with platform_features->rapl_msrs cleared 
platform_features->rapl_msrs describes the RAPL MSRs supported. While
RAPL Perf counters can be exposed from different kernel backend drivers,
e.g. RAPL MSR I/F driver, or RAPL TPMI I/F driver.

Thus, turbostat should first blindly probe all the available RAPL Perf
counters, and falls back to the RAPL MSR counters if they are listed in
platform_features->rapl_msrs.

With this, platforms that don't have RAPL MSRs can clear the
platform_features->rapl_msrs bits and use RAPL Perf counters only.

1ab2e19b4c tools/power turbostat: Introduce add_msr_counter() 
probe_rapl_msr() is reused for probing RAPL MSR counters, cstate MSR
counters and MPERF/APERF/SMI MSR counters, thus its name is misleading.

Similar to add_perf_counter(), introduce add_msr_counter() to probe a
counter via MSR. Introduce wrapper function add_rapl_msr_counter() at
the same time to add extra check for Zero return value for specified
RAPL counters.

No functional change intended.
