Linus Torvalds e1ba1c99da RISC-V Cleanups and ABI Fixes for 4.15-rc2
This tag contains a handful of small cleanups that are a result of
 feedback that didn't make it into our original patch set, either because
 the feedback hadn't been given yet, I missed the original emails, or
 we weren't ready to submit the changes yet.
 
 I've been maintaining the various cleanup patch sets I have as their own
 branches, which I then merged together and signed.  Each merge commit
 has a short summary of the changes, and each branch is based on your
 latest tag (4.15-rc1, in this case).  If this isn't the right way to do
 this then feel free to suggest something else, but it seems sane to me.
 
 Here's a short summary of the changes, roughly in order of how
 interesting they are.
 
 * libgcc.h has been moved from include/lib, where it's the only member,
   to include/linux.  This is meant to avoid tab completion conflicts.
 * VDSO entries for clock_get/gettimeofday/getcpu have been added.  These
   are simple syscalls now, but we want to let glibc use them from the
   start so we can make them faster later.
 * A VDSO entry for instruction cache flushing has been added so
   userspace can flush the instruction cache.
 * The VDSO symbol versions for __vdso_cmpxchg{32,64} have been removed,
   as those VDSO entries don't actually exist.
 * __io_writes has been corrected to respect the given type.
 * A new READ_ONCE in arch_spin_is_locked().
 * __test_and_op_bit_ord() is now actually ordered.
 * Various small fixes throughout the tree to enable allmodconfig to
   build cleanly.
 * Removal of some dead code in our atomic support headers.
 * Improvements to various comments in our atomic support headers.
