[GIT PULL] RISC-V updates for v6.19-rc7

[Paul Walmsley <pjw@kernel.org>]

Linus,

Please pull these RISC-V fixes for v6.19-rc7.  

The notable changes here are the three RISC-V timer compare register 
update sequence patches.  These only apply to RV32 systems and are related 
to the 64-bit timer compare value being split across two separate 32-bit 
registers.  We weren't using the appropriate three-write sequence, 
documented in the RISC-V ISA specifications, to avoid spurious timer 
interrupts during the update sequence; so, these patches now use the 
recommended sequence.  This doesn't affect 64-bit RISC-V systems, since 
the timer compare value fits inside a single register and can be updated 
with a single write.

thanks,

- Paul

  riscv: Add intermediate cast to 'unsigned long' in __get_user_asm (2026-01-22 20:21:14 -0700)

----------------------------------------------------------------
RISC-V updates for v6.19-rc7

- Fix the RISC-V timer compare register update sequence on RV32
  systems to use the recommended sequence in the RISC-V ISA manual.
  This avoids spurious interrupts during updates

- Add a dependence on the new CONFIG_CACHEMAINT_FOR_DMA Kconfig symbol
  for Renesas and StarFive RISC-V SoCs

- Add a temporary workaround for a Clang compiler bug caused by using
  asm_goto_output for get_user()

- Clarify our documentation around to specifically state a particular
  ISA specification version for a chapter number reference
