r186211: Remove obsolete AT_DEBUG stuff. 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. Approved by: re (Ken Smith), kib(mentor)

MFC r184501:

The code in linux_proc_exit() contains a race when multiple linux based processes exits at the same time. The linux_emuldata structure is freed but p->p_emuldata is left as a dangling pointer to the just freed memory. The check for W_EXIT in the loop scanning the child processes isn't safe since the state of the child process can change right afterwards. Lock the process and check the W_EXIT before delivering signal. Approved by: re (kensmith)

change the code to include "thread" argument to the vn_lock() which got removed in HEAD: Getdents requires padding with 2 bytes instead of 1 byte as with getdents64. The last byte is used for storing the d_type, add this to plain getdents case where it was missing before. Also change the code to use strlcpy instead of plain strcpy. This changes fix the getdents crash we had reports about (hl2 server etc.) PR: kern/117010 MFC after: 1 week Submitted by: Dmitry Chagin (dchagin@) Tested by: MITA Yoshio Approved by: kib (mentor) Approved by: re (kensmith)
