10: The putback of the following bugs into Nevada build 77 constitutes a
11: belated flag day for folks maintaining build machines and/or  running
12: nightly builds.
13: 
14:     6453272 ctfmerge uses the largest pagesize from getpagesizes() which can be bad on systems with giant pages
15:     6543997 divide by 0 panic in page_geti_contig_pages during 1g page testing
16:     6587615 1g pagesize support on AMD family 0x10 processors
17:     6588824 throttling large page coalescing needs to be revisited for gigantic pages
18:     6613824 legacy applications (java) should be prevented from inadvertantly using 1g pagesize
19: 
20: These fixes will be in release:
21: 
22:         snv_77
23: 
24: With 6613824, newly compiled programs that call getpagesizes, like ctfmerge, will call the new libc entry point getpagesizes2 instead.
25: 
26: Nevada build systems running pre Nevada Build 77 (nv77) will get the following fatal error when running a nightly build with the new post nv77 ctfmerge which was recently putback to onnv-tools.
27: 
28: /ld.so.1: ctfmerge: fatal: relocation error: file /ws/onnv-tools/onbld/bin/i386/ctfmerge: symbol getpagesizes2: referenced symbol not found/
29: 
30: Nevada build systems should be bfu’ed with nv77 or later to get the libc with getpagesizes2 needed by ctfmerge. Or the -t option can be specified in NIGHTLY_OPTIONS of the env file prior to running nightly.
31: 
32: Apologies for the confusion,
