This series removes the implicit assumption that RISC-V supports exactly
eight IPI message types.

Currently, the SBI, CLINT and ACLINT SSWI IPI providers use
BITS_PER_BYTE when sizing the generic IPI mux, while IMSIC carries a
separate IMSIC_NR_IPI definition set to 8. These values happen to match
IPI_MAX today, but neither is the proper source of truth for the number
of RISC-V IPI message types.

Move enum ipi_message_type to asm/smp.h so IPI providers can use IPI_MAX
directly, then replace the BITS_PER_BYTE and IMSIC_NR_IPI uses with
IPI_MAX.

This also makes adding future RISC-V IPI message types independent of
the current eight-entry assumption.

GUO Ren (XuanTie) (5):

  riscv: sbi: Use IPI_MAX for SBI IPI muxing
  clocksource: clint: Use IPI_MAX for IPI muxing
  irqchip/aclint-sswi: Use IPI_MAX for IPI muxing
  irqchip/imsic: Use IPI_MAX instead of IMSIC_NR_IPI

The IPI message type enumeration (and therefore IPI_MAX) is currently
private to arch/riscv/kernel/smp.c.  Several IPI providers need to know
the exact number of IPIs that the architecture requires, so move the
enum into the public header.

This is a pure code movement with no functional change.

Now that IPI_MAX is visible from <asm/smp.h>, replace the hard-coded
BITS_PER_BYTE with the proper symbolic constant in the SBI IPI
extension driver.

No functional change; IPI_MAX is still 8.

Replace the hard-coded BITS_PER_BYTE with IPI_MAX now that the constant
is exported from riscv asm/smp.h.

IMSIC was defining its own IMSIC_NR_IPI (= 8) which happened to match
the architecture's IPI_MAX. Now that IPI_MAX is exported from riscv
asm/smp.h, use the architecture constant and drop the private define.

This keeps the number of multiplexed IPIs in sync with the rest of the
RISC-V IPI infrastructure.
