selftests/bpf: Fix uprobe_multi compilation error
[ Upstream commit c27d8235ba97139d7a085367ff57773902eb3fc5 ] When building selftests, the following was seen: uprobe_multi.c: In function ‘trigger_uprobe’: uprobe_multi.c:108:40: error: ‘MADV_PAGEOUT’ undeclared (first use in this function) 108 | madvise(addr, page_sz, MADV_PAGEOUT); | ^~~~~~~~~~~~ uprobe_multi.c:108:40: note: each undeclared identifier is reported only once for each function it appears in make: *** [Makefile:850: bpf-next/tools/testing/selftests/bpf/uprobe_multi] Error 1 ...even with updated UAPI headers. It seems the above value is defined in UAPI <linux/mman.h> but including that file triggers other redefinition errors. Simplest solution is to add a guarded definition, as was done for MADV_POPULATE_READ.
