-Subject: [PATCH 01/10] fix Makefile so "make install" works before
- include/bits symlink exists
-
-previously, determination of the list of header files for installation
-depended on the include/bits symlink (to the arch-specific files)
-already having been created. in other words, running "make install"
-immediately after configure without first running "make" caused the
-bits headers not to be installed.
-
-the solution I have applied is to pull the list of headers directly
-from arch/$(ARCH)/bits rather than include/bits, and likewise to
-install directly from arch/$(ARCH)/bits rather than via the symlink.
-
-at this point, the only purpose served by keeping the symlink around
-is that it enables use of the in-tree headers and libs directly via -I
-and -L, which can be useful when testing against a new version of the
-library before installing it. on the other hand, removing the bits
-symlink would be beneficial if we ever want to support building
-multiple archs in the same source tree.

-Subject: [PATCH 07/10] fix invalid library phdr pointers passed to callback
- from dl_iterate_phdr
-
-map_library was saving pointers to an automatic-storage buffer rather
-than pointers into the mapping. this should be a fairly simple fix,
-but the patch here is slightly complicated by two issues:
-
-1. supporting gratuitously obfuscated ELF files where the program
-headers are not right at the beginning of the file.
-
-2. cleaning up the map_library function so that data isn't clobbered
-by the time we need it.

-Subject: [PATCH 10/10] make posix_spawn (and functions that use it) use
- CLONE_VFORK flag
-
-this is both a minor scheduling optimization and a workaround for a
-difficult-to-fix bug in qemu app-level emulation.
-
-from the scheduling standpoint, it makes no sense to schedule the
-parent thread again until the child has exec'd or exited, since the
-parent will immediately block again waiting for it.
-
-on the qemu side, as regular application code running on an underlying
-libc, qemu cannot make arbitrary clone syscalls itself without
-confusing the underlying implementation. instead, it breaks them down
-into either fork-like or pthread_create-like cases. it was treating
-the code in posix_spawn as pthread_create-like, due to CLONE_VM, which
-caused horribly wrong behavior: CLONE_FILES broke the synchronization
-mechanism, CLONE_SIGHAND broke the parent's signals, and CLONE_THREAD
-caused the child's exec to end the parent -- if it hadn't already
-crashed. however, qemu special-cases CLONE_VFORK and emulates that
-with fork, even when CLONE_VM is also specified. this also gives
-incorrect semantics for code that really needs the memory sharing, but
-posix_spawn does not make use of the vm sharing except to avoid
-momentary double commit charge.
-
-programs using posix_spawn (including via popen) should now work
-correctly under qemu app-level emulation.
