+Subject: [PATCH] include linux/sysinfo.h directly
+
+This is done to avoid the kernel header linux/kernel.h to use
+__GLIBC__ define to decide on if libc implements sysinfo() API
+or not. Kernel headers should be independent of such assumptions
+but until its done in right place, change the local header
+override to avoid this assumption
