Please apply commit d08c84e01afa ("perf sched: Cast PTHREAD_STACK_MIN to int ...") to v5.10.y and older

[Guenter Roeck <linux@xxxxxxxxxxxx>]

Hi Greg,

Observed with Ubuntu-22.04:

In v5.10.y and older kernels, perf may fail to compile with the following error.

In file included from util/evlist.h:6,
                 from builtin-sched.c:6:
builtin-sched.c: In function ‘create_tasks’:
tools/include/linux/kernel.h:45:17: error: comparison of distinct pointer types lacks a cast [-Werror]
   45 |  (void) (&_max1 == &_max2);  \
      |                 ^~
builtin-sched.c:662:13: note: in expansion of macro ‘max’
  662 |    (size_t) max(16 * 1024, PTHREAD_STACK_MIN));

The problem is fixed upstream with commit d08c84e01afa ("perf sched: Cast PTHREAD_STACK_MIN
to int as it may turn into sysconf(__SC_THREAD_STACK_MIN_VALUE)". Please apply this commit
to v5.10.y and older kernel branches.

Thanks,
Guenter
