Linus Torvalds acda701bf1 RISC-V Fixes for 5.11-rc4
There are a few more fixes than a normal rc4, largely due to the bubble
 introduced by the holiday break:
 
 * A fix to return -ENOSYS for syscall number -1, which previously
   returned an uninitialized value.
 * A fix to time_init() to ensure of_clk_init() has been called, without
   which clock drivers may not be initialized.
 * A fix to the sifive,uart0 driver to properly display the baud rate.  A
   fix to initialize MPIE that allows interrupts to be processed during
   system calls.
 * A fix to avoid erronously begin tracing IRQs when interrupts are
   disabled, which at least triggers suprious lockdep failures.
 * A workaround for a warning related to calling smp_processor_id() while
   preemptible.  The warning itself is suprious on currently availiable
   systems.
 * A fix to properly include the generic time VDSO calls.  A fix to our
   kasan address mapping.  A fix to the HiFive Unleashed device tree,
   which allows the Ethernet PHY to be properly initialized by Linux (as
   opposed to relying on the bootloader).
 * A defconfig update to include SiFive's GPIO driver, which is present
   on the HiFive Unleashed and necessary to initialize the PHY.
 * A fix to avoid allocating memory while initializing reserved memory.
 * A fix to avoid allocating the last 4K of memory, as pointers there
   alias with syscall errors.
 
 There are also two cleanups that should have no functional effect but do
 fix build warnings:
 
 * A cleanup to drop a duplicated definition of PAGE_KERNEL_EXEC.
 * A cleanup to properly declare the asm register SP shim.
 * A cleanup to the rv32 memory size Kconfig entry, to reflect the actual
   size of memory availiable.
