arm_pmu interrupts are maked as PERCPU even when these are not local
physical interrupts to a single CPU. When using non-local interrupts,
interrupts marked as PERCPU will not get freed not disabled properly
by the PMU driver.

Check if interrupts are local to a single CPU with PERCPU_DEVID since
this is what the PMU driver really needs to know.

Now that the ARM ARM clearly specifies the rules for inferring
the values of the ID register fields, fix the types of the
feature bits we have in the kernel.

As per ARM ARM DDI0487B.b, section D10.1.4 "Principles of the
ID scheme for fields in ID registers" lists the registers to
which the scheme applies along with the exceptions.

This patch changes the relevant feature bits from FTR_EXACT
to FTR_LOWER_SAFE to select the safer value. This will enable
an older kernel running on a new CPU detect the safer option
rather than completely disabling the feature.

Based on: ARM Architecture Reference Manual, ARMv8 (DDI 0487B.b).

ARMv8.1 introduces the optional feature ARMv8.1-TTHM which can trigger a
new type of memory abort. This exception is triggered when hardware update
of page table flags is not atomic in regards to other memory accesses.
Replace the corresponding unknown entry with a more accurate one.

Cf: Section D10.2.28 ESR_ELx, Exception Syndrome Register (p D10-2381),
section D4.4.11 Restriction on memory types for hardware updates on page
tables (p D4-2116 - D4-2117).

ARMv8.2 does not add new exception types, however it is worth mentioning
that when obligatory feature RAS (optional for ARMv8.{0,1}) is implemented,
exceptions related to "Synchronous parity or ECC error on memory access,
not on translation table walk" become reserved and should not occur.

IORT revision C introduced SMMUv3 and PMCG MSI support by adding
specific mapping entries in the SMMUv3/PMCG subtables to retrieve
the device ID and the ITS group it maps to for a given SMMUv3/PMCG
IORT node.

Introduce a mapping function (ie iort_get_id_mapping_index()), that
for a given IORT node looks up if an ITS specific ID mapping entry
exists and if so retrieve the corresponding mapping index in the IORT
node mapping array.

Since an ITS specific index mapping can be present for an IORT
node that is not a leaf node (eg SMMUv3 - to describe its own
ITS device ID) special handling is required for two steps mapping
cases such as PCI/NamedComponent--->SMMUv3--->ITS because the SMMUv3
ITS specific index mapping entry should be skipped to prevent the
IORT API from considering the mapping entry as a regular mapping one.

If we take the following IORT topology example:

|----------------------|
|  Root Complex Node   |
|----------------------|
|    map entry[x]      |
|----------------------|
|       id value       |
| output_reference     |
|---|------------------|
    |
    |   |----------------------|
    |-->|        SMMUv3        |
        |----------------------|
        |     SMMUv3 dev ID    |
        |     mapping index 0  |
        |----------------------|
        |      map entry[0]    |
        |----------------------|
        |       id value       |
        | output_reference-----------> ITS 1 (SMMU MSI domain)
        |----------------------|
        |      map entry[1]    |
        |----------------------|
        |       id value       |
        | output_reference-----------> ITS 2 (PCI MSI domain)
        |----------------------|

where the SMMUv3 ITS specific mapping entry is index 0 and it
represents the SMMUv3 ITS specific index mapping entry (describing its
own ITS device ID), we need to skip that mapping entry while carrying
out the Root Complex Node regular mappings to prevent erroneous
translations.

Reuse the iort_get_id_mapping_index() function to detect the ITS
specific mapping index for a specific IORT node and skip it in the IORT
mapping API (ie iort_node_map_id()) loop to prevent considering it a
normal PCI/Named Component ID mapping entry.

Current IORT code provides a function (ie iort_get_fwnode())
which looks up a struct fwnode_handle pointer through a
struct acpi_iort_node pointer for SMMU components but it
lacks a function that implements the reverse look-up, namely
struct fwnode_handle* -> struct acpi_iort_node*.

Devices that are not IORT named components cannot be retrieved through
their associated IORT named component scan interface because they just
are not represented in the ACPI namespace; the reverse look-up is
therefore required for all platform devices that represent IORT nodes
(eg SMMUs) so that the struct acpi_iort_node* can be retrieved from the
struct device->fwnode pointer.

The current delay implementation uses the yield instruction, which is a
hint that it is beneficial to schedule another thread. As this is a hint,
it may be implemented as a NOP, causing all delays to be busy loops. This
is the case for many existing CPUs.

Taking advantage of the generic timer sending periodic events to all
cores, we can use WFE during delays to reduce power consumption. This is
beneficial only for delays longer than the period of the timer event
stream.

If timer event stream is not enabled, delays will behave as yield/busy
loops.

The arch timer configuration for a CPU might get reset after suspending
said CPU.

In order to reliably use the event stream in the kernel (e.g. for delays),
we keep track of the state where we can safely consider the event stream as
properly configured. After writing to cntkctl, we issue an ISB to ensure
that subsequent delay loops can rely on the event stream being enabled.

Currently we inconsistently log identifying information for the boot CPU
and secondary CPUs. For the boot CPU, we log the MIDR and MPIDR across
separate messages, whereas for the secondary CPUs we only log the MIDR.

In some cases, it would be useful to know the MPIDR of secondary CPUs,
and it would be nice for these messages to be consistent.

This patch ensures that in the primary and secondary boot paths, we log
both the MPIDR and MIDR in a single message, with a consistent format.
the MPIDR is consistently padded to 10 hex characters to cover Aff3 in
bits 39:32, so that IDs can be compared easily.

As you see in init/version.c, init_uts_ns.name.machine is initially
set to UTS_MACHINE.  There is no point to copy the same string.

I dug the git history to figure out why this line is here.  My best
guess is like this:

 - This line has been around here since the initial support of arm64
   by commit 9703d9d7 ("arm64: Kernel booting and initialisation").
   If ARCH (=arm64) and UTS_MACHINE (=aarch64) do not match,
   arch/$(ARCH)/Makefile is supposed to override UTS_MACHINE, but the
   initial version of arch/arm64/Makefile missed to do that.  Instead,
   the boot code copied "aarch64" to init_utsname()->machine.

 - Commit 94ed1f2c ("arm64: setup: report ELF_PLATFORM as the
   machine for utsname") replaced "aarch64" with ELF_PLATFORM to
   make "uname" to reflect the endianness.

 - ELF_PLATFORM does not help to provide the UTS machine name to rpm
   target, so commit cfa88c79 ("arm64: Set UTS_MACHINE in the
   Makefile") fixed it.  The commit simply replaced ELF_PLATFORM with
   UTS_MACHINE, but missed the fact the string copy itself is no longer
   needed.

 "This adds a new timer wheel function which is required for the
  conversion of the timer callback function from the 'unsigned long

   2) Many callers hand in a pointer to the timer or to the structure
      containing the timer, which happens via type casting both at setup
      and in the callback. This change gets rid of the typecasts.

  Once the conversion is complete, which is planned for 4.15, the old
  setup function and the intermediate typecast in the new setup function
  go away along with the data field in struct timer_list.
