+
+_FILE_OFFSET_BITS is a feature test macro to determine largefile

+needed to be set to 64 for supporting 64bit time_t on glibc on 32bit
+systems. If its undefined explicitly, then 64bit time_t can not be

+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

+Subject: [PATCH] workaround for overlapping sections in binary
+
+Problem: binary (typesize.bin) created from object file (typesize.o)
+with 'objcopy -O binary ... '. But typesize.o has relocatable objects that all
+copied with offset 0. This will lead to overlapping sections in binary.
+By fortunate syscalls.pl check magic bytes and ring the bell.
+
+This is naive workaround: skip .note.gnu.property section that overlap
+.rodata section.
+
+This not a bug of objcopy, https://sourceware.org/bugzilla/show_bug.cgi?id=27314

+      [klibc] Detect the sizes of various types, and make available to sysstub.ph.
+
+      This additional code effectively queries the C compiler for the sizes of
+      various types, and makes an associative array %typesize available to
+      sysstub.ph.  This is currently not used, but it's expected that some
+      architectures, e.g. s390, will need this to determine which registers
+      go where, and how many registers are needed.

+Subject: [PATCH] common.h: replace getline() with fgets
+
+There is an unofficial upstream patch adding a simple getline()
+to libmissing.h. Unfortunately the patch creates issues if the
+toolchain is using glibc (autotools cache?) so for the moment
+keep the old hack and wait for commits upstream.
+
+Fix:
+
+| ubi-utils/ubiformat.o: In function `prompt.constprop.4':
+| ubiformat.c:(.text+0x70): undefined reference to `getline'
