selftests/powerpc: make sub-folders buildable on their ownBuild breaks when executing make with run_tests for sub-foldersunder powerpc. This is because, CFLAGS and GIT_VERSION macros aredefined in Makefile of toplevel powerpc folder. make: Entering directory '/home/maddy/linux/tools/testing/selftests/powerpc/mm' gcc hugetlb_vs_thp_test.c ../harness.c ../utils.c -o /home/maddy/selftest_output//hugetlb_vs_thp_test hugetlb_vs_thp_test.c:6:10: fatal error: utils.h: No such file or directory 6 | #include "utils.h" | ^~~~~~~~~ compilation terminated.Fix this by adding the flags.mk in each sub-folder Makefile. Also removethe CFLAGS and GIT_VERSION macros from powerpc/ folder Makefile sincethe same is definied in flags.mkSigned-off-by: Madhavan Srinivasan Signed-off-by: Michael Ellerman Link: https://msgid.link/20240229093711.581230-3-maddy@linux.ibm.com List of files: /linux-6.15/tools/testing/selftests/powerpc/papr_vpd/Makefile

powerpc/selftests: Add test for papr-vpdAdd selftests for /dev/papr-vpd, exercising the common expected usecases:* Retrieve all VPD by passing an empty location code.* Retrieve the "system VPD" by passing a location code derived from DT root node properties, as done by the vpdupdate command.The tests also verify that certain intended properties of the driverhold:* Passing an unterminated location code to PAPR_VPD_CREATE_HANDLE gets EINVAL.* Passing a NULL location code pointer to PAPR_VPD_CREATE_HANDLE gets EFAULT.* Closing the device node without first issuing a PAPR_VPD_CREATE_HANDLE command to it succeeds.* Releasing a handle without first consuming any data from it succeeds.* Re-reading the contents of a handle returns the same data as the first time.Some minimal validation of the returned data is performed.The tests are skipped on systems where the papr-vpd driver does notinitialize, making this useful only on PowerVM LPARs at this point.Signed-off-by: Nathan Lynch Signed-off-by: Michael Ellerman Link: https://msgid.link/20231212-papr-sys_rtas-vs-lockdown-v6-12-e9eafd0c8c6c@linux.ibm.com List of files: /linux-6.15/tools/testing/selftests/powerpc/papr_vpd/Makefile
