commit 636a4799dd5bf11a1fcd209906c088ed948b821c
Author: Rich Felker <dalias@aerifal.cx>
Date:   Sun Mar 6 17:11:29 2016 -0500

    make configure check for unsupported (SPE) powerpc hard-float models
    
    the SPE ABI may be compatible with soft-float, but actually making it
    work requires some additional work, so for now it's best to make sure
    broken builds don't happen.

commit 5a92dd95c77cee81755f1a441ae0b71e3ae2bcdb
Author: Felix Fietkau <nbd@nbd.name>
Date:   Mon Jan 25 13:20:52 2016 +0100

    add powerpc soft-float support
    
    Some PowerPC CPUs (e.g. Freescale MPC85xx) have a completely different
    instruction set for floating point operations (SPE).
    Executing regular PowerPC floating point instructions results in
    "Illegal instruction" errors.
    
    Make it possible to run these devices in soft-float mode.

    env: avoid leaving dangling pointers in __env_map
    
    This is the minimal fix for __putenv leaving a pointer to freed heap
    storage in __env_map array, which could later on lead to errors such
    as double-free.

    add mips64 port
    
    patch by Mahesh Bodapati and Jaydeep Patil of Imagination
    Technologies.

commit 71392a91c333d47b6b3c8f99c897e3b5a7eb6d58
Author: Rich Felker <dalias@aerifal.cx>
Date:   Sun Mar 6 17:25:52 2016 +0000

    generalize mips-specific reloc code not to hard-code sym/type encoding
    
    this change is made in preparation for adding the mips64 port, which
    needs a 64-bit (and mips64-specific) form of the R_INFO macro, but
    it's a better abstraction anyway.
    
    based on part of the mips64 port patch by Mahesh Bodapati and Jaydeep
    Patil of Imagination Technologies.

    math: fix expf(-NAN) and exp2f(-NAN) to return -NAN instead of 0
    
    expf(-NAN) was treated as expf(-large) which unconditionally
    returns +0, so special case +-NAN.
    reported by Petr Hosek.

    add sched_getcpu vDSO support
    
    This brings the call to an actually usable speed.
    Quick unscientific benchmark: 14ns : 102ns :: vDSO : syscall

Date:   Wed Mar 2 17:26:26 2016 +0100

    add sched_getcpu
    
    This is a GNU extension, but a fairly minor one, for a system call that
    otherwise has no libc wrapper.

    fix ^* at the start of a complete BRE
    
    This is a workaround to treat * as literal * at the start of a BRE.
    
    Ideally ^ would be treated as an anchor at the start of any BRE
    subexpression and similarly $ would be an anchor at the end of any
    subexpression.  This is not required by the standard and hard to do
    with the current code, but it's the existing practice.  If it is
    changed, * should be treated as literal after such anchor as well.

    fix * at the start of a BRE subexpression
    
    commit 7eaa76fc2e7993582989d3838b1ac32dd8abac09 made * invalid at
    the start of a BRE subexpression, but it should be accepted as
    literal * there according to the standard.
    
    This patch does not fix subexpressions starting with ^*.

    handle non-matching address family entries in hosts file
    
    name_from_hosts failed to account for the possibility of an address
    family error from name_from_numeric, wrongly counting such a return as
    success and using the uninitialized address data as part of the
    results passed up to the caller.
    
    non-matching address family entries cannot simply be ignored or
    results would be inconsistent with respect to whether AF_UNSPEC or a
    specific address family is queried. instead, record that a
    non-matching entry was seen, and fail the lookup with EAI_NONAME of no
    matching-family entries are found.

    make aarch64 atomic_arch.h report that it defines pointer-sized ll/sc
    
    at present this is done only for consistency, since this file defines
    its own a_cas_p rather than using the new generic one from atomic.h
    added in commit 225f6a6b5b7173b6655e4f5d49b5b9fea70bf3bb. these
    definitions may however be useful if we ever need to add other
    pointer-sized atomic operations.

Author: Bobby Bingham <koorogi@koorogi.info>
Date:   Mon Feb 22 21:14:23 2016 -0600

    allow implementing a_cas_p with pointer-sized ll/sc
    
    No current ports do this, but it will be useful for porting to 64-bit ll/sc
    architectures, such as mips64 and powerpc64.
