Linus Torvalds 1009aa1205 RISC-V Updates for the 4.19 Merge Window
This tag contains some major improvements to the RISC-V port, including
 the necessary interrupt controller and timer support to actually make it
 to userspace.  Support for three devices has been added:
 
 * Support for the ISA-mandated timers on RISC-V systems.
 * Support for the ISA-mandated first-level interrupt controller on
   RISC-V systems, which is handled as part of our core arch code because
   it's very small and tightly tied to the ISA.
 * Support for SiFive's platform-level interrupt controller, which talks
   to the actual devices.
 
 In addition to these new devices, there are a handful of cleanups all
 over the RISC-V tree:
 
 * Build fixes for various configurations
     * A fix to the vDSO build's makefile so it respects CFLAGS.
     * The addition of __lshrti3, a libgcc derived function necessary for
       some 32-bit configurations.
     * !SMP && PERF_EVENTS
 * Cleanups to the arch code to remove the remnants of old versions of
   the drivers that were just properly submitted.
     * Some dead code from the timer driver, most of which wasn't ever
       even compiled.
     * Cleanups of some interrupt #defines, which are now local to the
       interrupt handling code.
 * Fixes to ptrace(), which while not being sufficient to fully make GDB
   work are at least sufficient to get simple GDB tasks to work.
 * Early printk support via RISC-V's architecturally mandated SBI console
   device.
 * A fix to our early debug trap handler to ensure it's always aligned.
 
 These patches have all been through a fairly extensive review process,
 but as this enables a whole pile of functionality (ie, userspace) I'm
 confident we'll need to submit a few more patches.  The only concrete
 issues I know about are the sys_riscv_flush_icache patches, but as I
 managed to screw those up on Friday I figured it'd be best to let them
 bake another week.
 
 This tag boots a Fedora root filesystem on QEMU's master branch for me,
 and before this morning's rebase (from 4.18-rc8 to 4.18) it booted on
 the HiFive Unleashed.
 
 Thanks to Christoph Hellwig and the other guys at WD for getting the new
 drivers in shape!
