+Subject: [PATCH] fix mmap syscall on ARM
+
+several issues found while debugging on the Debian armhf porterbox
+on #debian-arm with pbrook (Paul Brook) and lindi- (Timo Juhani Lindfors)
+
+- the comment only applies to the non-EABI part of the function
+- "This is ARM code. But you've not maked mmap as a function symbol."
+=> use the arm-features.h macros
