riscv: hwprobe: avoid uninitialized variable use in hwprobe_arch_id() (2025-10-18 09:36:36 -0600)
- Paul
----------------------------------------------------------------
RISC-V updates for v6.18-rc3
Several RISC-V fixes for v6.18-rc3:
- Close a race during boot between userspace vDSO usage and some
late-initialized vDSO data
- Improve performance on systems with non-CPU-cache-coherent
DMA-capable peripherals by enabling write combining on
pgprot_dmacoherent() allocations
- Add human-readable detail for RISC-V IPI tracing
- Provide more information to zsmalloc on 64-bit RISC-V to improve
allocation
- Silence useless boot messages about CPUs that have been disabled in
DT
- Resolve some compiler and smatch warnings and remove a redundant macro
----------------------------------------------------------------
Anup Patel (2):
RISC-V: Define pgprot_dmacoherent() for non-coherent devices
RISC-V: Don't print details of CPUs disabled in DT
Jingwei Wang (1):
