Pull mod_devicetable.h header split from Uwe Kleine-König:
 "Split <linux/mod_devicetable.h> in per subsystem headers

  <linux/mod_devicetable.h> is included transitively in nearly every
  driver in an x86_64 allmodconfig build of v7.1:

      $ find drivers -name \*.o -not -name \*.mod.o | wc -l
      21330
      $ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l
      17038

  The result of this mixture of different and unrelated subsystem
  details is that even when touching an obscure device id struct most of
  the kernel needs to be recompiled. Given that each driver typically
  only needs one or two of these structures, splitting into per
  subsystem headers and only including what is really needed reduces the
  amount of needed recompilation.

  This split is implemented in the first commit and then after some
  preparatory work in the following commits, the last two replace
  includes of <linux/mod_devicetable.h> by the actually needed more
  specific headers.

  There are still a few instances left, but the ones with high impact
  (that is in headers that are used a lot) and the easy ones (.c files)
  are handled. These remaining includes will be addressed during the
  next merge window"

Traditionally <linux/mod_devicetable.h> was a header defining a plethora
of structs, among them struct cpu_features. This was split now with the
objective that only the relevant bits are included.

Currently <linux/mod_devicetable.h> is transitively included in
arch/loongarch/kvm/main.c via:

	arch/loongarch/kvm/main.c ->
	<linux/kvm_host.h> ->
	<linux/entry-virt.h> ->
	<linux/resume_user_mode.h> ->
	<linux/memcontrol.h> ->
	<linux/cgroup.h> ->
	<linux/kernel_stat.h> ->
	<linux/interrupt.h> ->
	<linux/hardirq> ->
	<asm/hardirq.h> ->
	<linux/irq.h> ->
	<asm/irq.h> ->
	<linux/irqdomain.h> ->
	<linux/of.h> ->
	<linux/mod_devicetable.h>

To keep struct cpu_features available once <linux/of.h> stops including
<linux/mod_devicetable.h>, include it here explicitly.

Currently predictor flush on memory reuse is done for all BPF JIT
allocations, but only cBPF programs can be loaded by an unprivileged user.
eBPF is privileged by default, and flushing predictors for all CPUs on
every eBPF reuse penalizes the common case for no security benefit.

eBPF allocations can be frequent on busy systems, only flush predictors
for cBPF programs. Trampoline and dispatcher allocations also skip the
flush as they are eBPF-only.

The pointer to thread_info is always available in the $tp register, so
the call to bpf_get_smp_processor_id() can be inlined into a single load
instruction.

(1) Here is the sample test.c:

  #include <linux/bpf.h>
  #include <bpf/bpf_helpers.h>

  SEC("raw_tp/sys_enter")
  int test_cpuid(void *ctx)
  {
	  return bpf_get_smp_processor_id();
  }
  char _license[] SEC("license") = "GPL";

(2) Here are the test steps:

  sudo yum install libbpf-devel kernel-devel bpftool
  clang -target bpf -O2 -c test.c -o test.o
  sudo sysctl -w net.core.bpf_jit_enable=1
  sudo bpftool prog show name test_cpuid
  sudo rm -f /sys/fs/bpf/test_cpuid
  sudo bpftool prog load test.o /sys/fs/bpf/test_cpuid
  ID=$(sudo bpftool prog show pinned /sys/fs/bpf/test_cpuid | grep -oE '^[0-9]+')
  sudo bpftool prog dump jited id $ID

(3) Here are the test results:

Before: 6 instructions

  ...
  64:	lu12i.w	$t1, 1213
  68:	ori	$t1, $t1, 1680
  6c:	lu32i.d	$t1, 0
  70:	lu52i.d	$t1, $t1, -1792
  74:	jirl	$ra, $t1, 0
  78:	move	$a5, $a0
  ...

After: 1 instruction

  ...
  64:	ld.wu	$a5, $tp, 16
  ...

This is similar with commit 2ddec2c80b44 ("riscv, bpf: inline
bpf_get_smp_processor_id()").
