Merge tag 'riscv-for-linus-4.15-rc2_cleanups' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/linux
Pull RISC-V cleanups and ABI fixes from Palmer Dabbelt: "This 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" * tag 'riscv-for-linus-4.15-rc2_cleanups' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/linux: (23 commits) RISC-V: __io_writes should respect the length argument move libgcc.h to include/linux RISC-V: Clean up an unused include RISC-V: Allow userspace to flush the instruction cache RISC-V: Flush I$ when making a dirty page executable RISC-V: Add missing include RISC-V: Use define for get_cycles like other architectures RISC-V: Provide stub of setup_profiling_timer() RISC-V: Export some expected symbols for modules RISC-V: move empty_zero_page definition to C and export it RISC-V: io.h: type fixes for warnings RISC-V: use RISCV_{INT,SHORT} instead of {INT,SHORT} for asm macros RISC-V: use generic serial.h RISC-V: remove spin_unlock_wait() RISC-V: `sfence.vma` orderes the instruction cache RISC-V: Add READ_ONCE in arch_spin_is_locked() RISC-V: __test_and_op_bit_ord should be strongly ordered RISC-V: Remove smb_mb__{before,after}_spinlock() RISC-V: Remove __smp_bp__{before,after}_atomic RISC-V: Comment on why {,cmp}xchg is ordered how it is ...
