Subject: * elf/dl-load.c [__WORDSIZE==64] (FILEBUF_SIZE): Adjust the value
X-Git-Tag: upstream/2.30~16517
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=23e2554f5b50ab775a6ac1b02cd071f741ff8159;p=external%2Fglibc.git

* elf/dl-load.c [__WORDSIZE==64] (FILEBUF_SIZE): Adjust the value

	up.  We have more program header entries now and the note section
	was normally not loaded.

    question is how large are the ELF and program header combined.  The
