The quilt patch titled Subject: selftests/mm: fix build break when compiling pkey_util.c has been removed from the -mm tree. Its filename was selftests-mm-fix-build-break-when-compiling-pkey_utilc.patch

This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

------------------------------------------------------ From: Madhavan Srinivasan maddy@linux.ibm.com Subject: selftests/mm: fix build break when compiling pkey_util.c Date: Mon, 28 Apr 2025 18:49:34 +0530

Commit 50910acd6f615 ("selftests/mm: use sys_pkey helpers consistently") added a pkey_util.c to refactor some of the protection_keys functions accessible by other tests. But this broken the build in powerpc in two ways,

pkey-powerpc.h: In function `arch_is_powervm': pkey-powerpc.h:73:21: error: storage size of `buf' isn't known 73 | struct stat buf; | ^~~ pkey-powerpc.h:75:14: error: implicit declaration of function `stat'; did you mean `strcat'? [-Wimplicit-function-declaration] 75 | if ((stat("/sys/firmware/devicetree/base/ibm,partition-name", &buf) == 0) && | ^~~~ | strcat

Since pkey_util.c includes pkeys-helper.h, which in turn includes pkeys-powerpc.h, stat.h including is missing for "struct stat". This is fixed by adding "sys/stat.h" in pkeys-powerpc.h

Secondly,

pkey-powerpc.h:55:18: warning: format `%llx' expects argument of type `long long unsigned int', but argument 3 has type `u64' {aka `long unsigned int'} [-Wformat=] 55 | dprintf4("%s() changing %016llx to %016llx\n", | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 56 | __func__, __read_pkey_reg(), pkey_reg); | ~~~~~~~~~~~~~~~~~ | | | u64 {aka long unsigned int} pkey-helpers.h:63:32: note: in definition of macro `dprintf_level' 63 | sigsafe_printf(args); \ | ^~~~

These format specifier related warning are removed by adding "__SANE_USERSPACE_TYPES__" to pkeys_utils.c.
