Arnaldo Carvalho de Melo fbd11f086b perf sched: Cast PTHREAD_STACK_MIN to int as it may turn into sysconf(__SC_THREAD_STACK_MIN_VALUE) 
commit d08c84e01a upstream.

In fedora rawhide the PTHREAD_STACK_MIN define may end up expanded to a
sysconf() call, and that will return 'long int', breaking the build:

    45 fedora:rawhide                : FAIL gcc version 11.1.1 20210623 (Red Hat 11.1.1-6) (GCC)
      builtin-sched.c: In function 'create_tasks':
      /git/perf-5.14.0-rc1/tools/include/linux/kernel.h:43:24: error: comparison of distinct pointer types lacks a cast [-Werror]
         43 |         (void) (&_max1 == &_max2);              \
            |                        ^~
      builtin-sched.c:673:34: note: in expansion of macro 'max'
        673 |                         (size_t) max(16 * 1024, PTHREAD_STACK_MIN));
            |                                  ^~~
      cc1: all warnings being treated as errors

  $ grep __sysconf /usr/include/*/*.h
  /usr/include/bits/pthread_stack_min-dynamic.h:extern long int __sysconf (int __name) __THROW;
  /usr/include/bits/pthread_stack_min-dynamic.h:#   define PTHREAD_STACK_MIN __sysconf (__SC_THREAD_STACK_MIN_VALUE)
  /usr/include/bits/time.h:extern long int __sysconf (int);
  /usr/include/bits/time.h:# define CLK_TCK ((__clock_t) __sysconf (2))	/* 2 is _SC_CLK_TCK */
  $

So cast it to int to cope with that.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
