Some platform-MSI implementations require that power management is
redirected to the underlying interrupt chip device. To make this work
with per device MSI domains provide a new feature flag and let the
core code handle the setup of dev->pm_dev when set during device MSI
domain creation.

To support wire to MSI bridges proper in the MSI core infrastructure it is
required to have separate allocation/free interfaces which can be invoked
from the regular irqdomain allocaton/free functions.

The mechanism for allocation is:
  - Allocate the next free MSI descriptor index in the domain
  - Store the hardware interrupt number and the trigger type
    which was extracted by the irqdomain core from the firmware spec
    in the MSI descriptor device cookie so it can be retrieved by
    the underlying interrupt domain and interrupt chip
  - Use the regular MSI allocation mechanism for the newly allocated
    index which returns a fully initialized Linux interrupt on succes

This works because:
  - the domains have a fixed size
  - each hardware interrupt is only allocated once
  - the underlying domain does not care about the MSI index it only cares
    about the hardware interrupt number and the trigger type

The free function looks up the MSI index in the MSI descriptor of the
provided Linux interrupt number and uses the regular index based free
functions of the MSI core.

To support wire to MSI domains via the MSI infrastructure it is required to
use the firmware node of the device which implements this for creating the
MSI domain. Otherwise the existing firmware match mechanisms to find the
correct irqdomain for a wired interrupt which is connected to a wire to MSI
bridge would fail.

This cannot be used for the general case because not all devices provide
firmware nodes and all regular per device MSI domains are directly
associated to the device and have not be searched for.

irq_create_fwspec_mapping() requires translation of the firmware spec to a
hardware interrupt number and the trigger type information.

Wired interrupts which are connected to a wire to MSI bridge, like MBIGEN
are allocated that way. So far MBIGEN provides a regular irqdomain which
then hooks backwards into the MSI infrastructure. That's an unholy mess and
will be replaced with per device MSI domains which are regular MSI domains.

Interrupts on MSI domains are not supported by irq_create_fwspec_mapping(),
but for making the wire to MSI bridges sane it makes sense to provide a
special allocation/free interface in the MSI infrastructure. That avoids
the backdoors into the core MSI allocation code and just shares all the
regular MSI infrastructure.

Provide an optional translation callback in msi_domain_ops which can be
utilized by these wire to MSI bridges. No other MSI domain should provide a
translation callback. The default translation callback of the MSI
irqdomains will warn when it is invoked on a non-prepared MSI domain.

Provide functions to create and remove per device MSI domains which replace
the platform-MSI domains. The new model is that each of the devices which
utilize platform-MSI gets now its private MSI domain which is "customized"
in size and with a device specific function to write the MSI message into
the device.

This is the same functionality as platform-MSI but it avoids all the down
sides of platform MSI, i.e. the extra ID book keeping, the special data
structure in the msi descriptor. Further the domains are only created when
the devices are really in use, so the burden is on the usage and not on the
infrastructure.

Fill in the domain template and provide two functions to init/allocate and
remove a per device MSI domain.

Until all users and parent domain providers are converted, the init/alloc
function invokes the original platform-MSI code when the irqdomain which is
associated to the device does not provide MSI parent functionality yet.

Currently the irqdomain select callback is only invoked when the parameter
count of the fwspec arguments is not zero. That makes sense because then
the match is on the firmware node and eventually on the bus_token, which is
already handled in the core code.

The upcoming support for per device MSI domains requires to do real bus
token specific checks in the MSI parent domains with a zero parameter
count.

Make the gic-v3 select() callback handle that case.

Pull firewire fix from Takashi Sakamoto:
 "A change to accelerate the device detection step in some cases.

  In the self-identification step after bus-reset, all nodes in the same
  bus broadcast selfID packet including the value of gap count. The
  value is related to the cable hops between nodes, and used to
  calculate the subaction gap and the arbitration reset gap.

  When each node has the different value of the gap count, the
  asynchronous communication between them is unreliable, since an
  asynchronous transaction could be interrupted by another asynchronous
  transaction before completion. The gap count inconsistency can be
  resolved by several ways; e.g. the transfer of PHY configuration
  packet and generation of bus-reset.

  The current implementation of firewire stack can correctly detect the
  gap count inconsistency, however the recovery action from the
  inconsistency tends to be delayed after reading configuration ROM of
  root node. This results in the long time to probe devices in some
  combinations of hardware.

  Here the stack is changed to schedule the action as soon as possible"

We've had issues with gcc and 'asm goto' before, and we created a
'asm_volatile_goto()' macro for that in the past: see commits
3f0116c3 ("compiler/gcc4: Add quirk for 'asm goto' miscompilation
bug") and a9f18034 ("compiler/gcc4: Make quirk for
asm_volatile_goto() unconditional").

Then, much later, we ended up removing the workaround in commit
43c249ea ("compiler-gcc.h: remove ancient workaround for gcc PR
58670") because we no longer supported building the kernel with the
affected gcc versions, but we left the macro uses around.

Now, Sean Christopherson reports a new version of a very similar
problem, which is fixed by re-applying that ancient workaround.  But the
problem in question is limited to only the 'asm goto with outputs'
cases, so instead of re-introducing the old workaround as-is, let's
rename and limit the workaround to just that much less common case.

It looks like there are at least two separate issues that all hit in
this area:

 (a) some versions of gcc don't mark the asm goto as 'volatile' when it
     has outputs:

        https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98619
        https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110420

     which is easy to work around by just adding the 'volatile' by hand.

 (b) Internal compiler errors:

        https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110422

     which are worked around by adding the extra empty 'asm' as a
     barrier, as in the original workaround.

but the problem Sean sees may be a third thing since it involves bad
code generation (not an ICE) even with the manually added 'volatile'.

but the same old workaround works for this case, even if this feels a
bit like voodoo programming and may only be hiding the issue.

Pull tracing fixes from Steven Rostedt:

 - Fix broken direct trampolines being called when another callback is
   attached the same function.

   ARM 64 does not support FTRACE_WITH_REGS, and when it added direct
   trampoline calls from ftrace, it removed the "WITH_REGS" flag from
   the ftrace_ops for direct trampolines. This broke x86 as x86 requires
   direct trampolines to have WITH_REGS.

   This wasn't noticed because direct trampolines work as long as the
   function it is attached to is not shared with other callbacks (like
   the function tracer). When there are other callbacks, a helper
   trampoline is called, to call all the non direct callbacks and when
   it returns, the direct trampoline is called.

   For x86, the direct trampoline sets a flag in the regs field to tell
   the x86 specific code to call the direct trampoline. But this only
   works if the ftrace_ops had WITH_REGS set. ARM does things
   differently that does not require this. For now, set WITH_REGS if the
   arch supports WITH_REGS (which ARM does not), and this makes it work
   for both ARM64 and x86.

 - Fix wasted memory in the saved_cmdlines logic.

   The saved_cmdlines is a cache that maps PIDs to COMMs that tracing
   can use. Most trace events only save the PID in the event. The
   saved_cmdlines file lists PIDs to COMMs so that the tracing tools can
   show an actual name and not just a PID for each event. There's an
   array of PIDs that map to a small set of saved COMM strings. The
   array is set to PID_MAX_DEFAULT which is usually set to 32768. When a
   PID comes in, it will add itself to this array along with the index
   into the COMM array (note if the system allows more than
   PID_MAX_DEFAULT, this cache is similar to cache lines as an update of
   a PID that has the same PID_MAX_DEFAULT bits set will flush out
   another task with the same matching bits set).

   A while ago, the size of this cache was changed to be dynamic and the
   array was moved into a structure and created with kmalloc(). But this
   new structure had the size of 131104 bytes, or 0x20020 in hex. As
   kmalloc allocates in powers of two, it was actually allocating
   0x40000 bytes (262144) leaving 131040 bytes of wasted memory. The
   last element of this structure was a pointer to the COMM string array
   which defaulted to just saving 128 COMMs.

   By changing the last field of this structure to a variable length
   string, and just having it round up to fill the allocated memory, the
   default size of the saved COMM cache is now 8190. This not only uses
   the wasted space, but actually saves space by removing the extra
   allocation for the COMM names.

  paint ourselves into a corner when we tighten this further in order to
  comply with MS requirements on signed EFI code.

  Note that this protocol does not currently exist in x86 production
  systems in the field, only in Microsoft's fork of OVMF, but it will be
  mandatory for Windows logo certification for x86 PCs in the future.

   - Tighten ELF relocation checks on the RISC-V EFI stub

   - Give up if the new EFI memory attributes protocol fails spuriously
     on x86

   - Take care not to place the kernel in the lowest 16 MB of DRAM on
     x86

   - Omit special purpose EFI memory from memblock

   - Some fixes for the CXL CPER reporting code

   - Make the PE/COFF layout of mixed-mode capable images comply with a
     strict interpretation of the spec"

The kernel built with MCRUSOE is unbootable on Transmeta Crusoe.  It shows
the following error message:

  This kernel requires an i686 CPU, but only detected an i586 CPU.
  Unable to boot - please use a kernel appropriate for your CPU.

Remove MCRUSOE from the condition introduced in commit in Fixes, effectively
changing X86_MINIMUM_CPU_FAMILY back to 5 on that machine, which matches the
CPU family given by CPUID.
