 "Fix regression in GFP output in trace events

  It was reported that the GFP flags in trace events went from human
  readable to just their hex values:

      gfp_flags=GFP_HIGHUSER_MOVABLE|__GFP_COMP to gfp_flags=0x140cca

  This was caused by a change that added the use of enums in calculating
  the GFP flags.

  As defines get translated into their values in the trace event format
  files, the user space tooling could easily convert the GFP flags into
  their symbols via the __print_flags() helper macro.

  The problem is that enums do not get converted, and the names of the
  enums show up in the format files and user space tooling cannot
  translate them.

  Add TRACE_DEFINE_ENUM() around the enums used for GFP flags which is
  the tracing infrastructure macro that informs the tracing subsystem
  what the values for enums and it can then expose that to user space"

      tracing: gfp: Fix the GFP enum values shown for user space tracing tools · 60295b94
      Steven Rostedt authored 
      Tracing tools like perf and trace-cmd read the /sys/kernel/tracing/events/*/*/format
files to know how to parse the data and also how to print it. For the
"print fmt" portion of that file, if anything uses an enum that is not
exported to the tracing system, user space will not be able to parse it.

The GFP flags use to be defines, and defines get translated in the print
fmt sections. But now they are converted to use enums, which is not.

The mm_page_alloc trace event format use to have:

  print fmt: "page=%p pfn=0x%lx order=%d migratetype=%d gfp_flags=%s",
    REC->pfn != -1UL ? (((struct page *)vmemmap_base) + (REC->pfn)) : ((void
    *)0), REC->pfn != -1UL ? REC->pfn : 0, REC->order, REC->migratetype,
    (REC->gfp_flags) ? __print_flags(REC->gfp_flags, "|", {( unsigned
    long)(((((((( gfp_t)(0x400u|0x800u)) | (( gfp_t)0x40u) | (( gfp_t)0x80u) |
    (( gfp_t)0x100000u)) | (( gfp_t)0x02u)) | (( gfp_t)0x08u) | (( gfp_t)0)) |
    (( gfp_t)0x40000u) | (( gfp_t)0x80000u) | (( gfp_t)0x2000u)) & ~((
    gfp_t)(0x400u|0x800u))) | (( gfp_t)0x400u)), "GFP_TRANSHUGE"}, {( unsigned
    long)((((((( gfp_t)(0x400u|0x800u)) | (( gfp_t)0x40u) | (( gfp_t)0x80u) |
    (( gfp_t)0x100000u)) | (( gfp_t)0x02u)) | (( gfp_t)0x08u) | (( gfp_t)0)) ...

Where the GFP values are shown and not their names. But after the GFP
flags were converted to use enums, it has:

  print fmt: "page=%p pfn=0x%lx order=%d migratetype=%d gfp_flags=%s",
    REC->pfn != -1UL ? (vmemmap + (REC->pfn)) : ((void *)0), REC->pfn != -1UL
    ? REC->pfn : 0, REC->order, REC->migratetype, (REC->gfp_flags) ?
    __print_flags(REC->gfp_flags, "|", {( unsigned long)((((((((
    gfp_t)(((((1UL))) << (___GFP_DIRECT_RECLAIM_BIT))|((((1UL))) <<
    (___GFP_KSWAPD_RECLAIM_BIT)))) | (( gfp_t)((((1UL))) << (___GFP_IO_BIT)))
    | (( gfp_t)((((1UL))) << (___GFP_FS_BIT))) | (( gfp_t)((((1UL))) <<
    (___GFP_HARDWALL_BIT)))) | (( gfp_t)((((1UL))) << (___GFP_HIGHMEM_BIT))))
    | (( gfp_t)((((1UL))) << (___GFP_MOVABLE_BIT))) | (( gfp_t)0)) | ((
    gfp_t)((((1UL))) << (___GFP_COMP_BIT))) ...

Where the enums names like ___GFP_KSWAPD_RECLAIM_BIT are shown and not their
values. User space has no way to convert these names to their values and
the output will fail to parse. What is shown is now:

  mm_page_alloc:  page=0xffffffff981685f3 pfn=0x1d1ac1 order=0 migratetype=1 gfp_flags=0x140cca

The TRACE_DEFINE_ENUM() macro was created to handle enums in the print fmt
files. This causes them to be replaced at boot up with the numbers, so
that user space tooling can parse it. By using this macro, the output is
back to the human readable:

  mm_page_alloc: page=0xffffffff981685f3 pfn=0x122233 order=0 migratetype=1 gfp_flags=GFP_HIGHUSER_MOVABLE|__GFP_COMP

      Pull tracing fixes from Steven Rostedt:

 - Fix a regression in the irqsoff and wakeup latency tracing

   The function graph tracer infrastructure has become generic so that
   fprobes and BPF can be based on it. As it use to only handle function
   graph tracing, it would always calculate the time the function
   entered so that it could then calculate the time it exits and give
   the length of time the function executed for. But this is not needed
   for the other users (fprobes and BPF) and reading the clock adds a
   non-negligible overhead, so the calculation was moved into the
   function graph tracer logic.

   But the irqsoff and wakeup latency tracers, when the "display-graph"
   option was set, would use the function graph tracer to calculate the
   times of functions during the latency. The movement of the calltime
   calculation made the value zero for these tracers, and the output no
   longer showed the length of time of each tracer, but instead the
   absolute timestamp of when the function returned (rettime - calltime
   where calltime is now zero).

   Have the irqsoff and wakeup latency tracers also do the calltime
   calculation as the function graph tracer does and report the proper
   length of the function timings.

 - Update the tracing display to reflect the new preempt lazy model

   When the system is configured with preempt lazy, the output of the
   trace data would state "unknown" for the current preemption model.
   Because the lazy preemption model was just added, make it known to
   the tracing subsystem too. This is just a one line change.

 - Document multiple function graph having slightly different timings

   Now that function graph tracer infrastructure is separate, this also
   allows the function graph tracer to run in multiple instances (it
   wasn't able to do so before). If two instances ran the function graph
   tracer and traced the same functions, the timings for them will be
   slightly different because each does their own timings and collects
   the timestamps differently. Document this to not have people be
   confused by it.

      drm/xe: Mark ComputeCS read mode as UC on iGPU · b1231ff7
      Matthew Brost authored and Thomas Hellström's avatar Thomas Hellström committed 
      
RING_CMD_CCTL read index should be UC on iGPU parts due to L3 caching
structure. Having this as WB blocks ULLS from being enabled. Change to
UC to unblock ULLS on iGPU.

v2:
 - Drop internal communications commnet, bspec is updated

   - core: make page_pool_ref_netmem work with net iovs

   - ipv4: route: fix drop reason being overridden in
     ip_route_input_slow

  Previous releases - regressions:

   - bpf: fix bpf_sk_select_reuseport() memory leak

   - openvswitch: fix lockup on tx to unregistering netdev with carrier

   - mptcp: be sure to send ack when mptcp-level window re-opens

   - eth:
      - bnxt: always recalculate features after XDP clearing, fix
        null-deref
      - mlx5: fix sub-function add port error handling
      - fec: handle page_pool_dev_alloc_pages error

  Previous releases - always broken:
