It never should have been committed in the first place, let alone migrated to linux emulation. r189362: Add AT_PLATFORM, AT_HWCAP and AT_CLKTCK auxiliary vector entries which are used by glibc. This silents the message "2.4+ kernel w/o ELF notes?" from some programs at start, among them are top and pkill. Do the assignment of the vector entries in elf_linux_fixup() as it is done in glibc. Fix some minor style issues.

The search order of a brand is changed, now first of all the ".note.ABI-tag" is looked through. Move code which fetch osreldate for ELF binary to check_note() handler. r189919: Use the properly sized types for ELF object header and program headers. This fixes osrel fetching from the FreeBSD branding note for the 64bit platforms (bug introduced by r189771). r190264: Fix several issues with parsing the notes for ELF objects. Badly formed ELF note may cause the caclulated pointer to the next note to point both after the note region, that was checked in the code, but also to point before the region, that was not checked [1]. Remember the first note location in note0 and leap out if the note is not between note0 and note_end. In the similar way, badly formed note may cause infinite loop by pointing next note into the same or previous note. Guard against this by limiting amount of loop iterations by arbitrary choosen big number. For clarity, check the calculated note alignment in each iteration.

This fixes a bug were 32-bit binaries would run with a different floating point exception mask under FreeBSD/amd64 vs FreeBSD/i386. This commit also includes a few other minor changes to keep the code in sync with 8. Approved by: re (kib) 2009-03-24T02:09:48Z David E.
