removal of the LD_TRACE_PRELINKING, and LD_USE_LOAD_BIAS, environment
variables and their functionality in the dynamic loader.
+* The Linux kernel version check has been removed along with the
+ LD_ASSUME_KERNEL environment variable. The minimum kernel used to built
+ glibc is still provided through NT_GNU_ABI_TAG ELF note and also printed
+ when libc.so is issued directly.
