Merge patch series "riscv: fix debug_pagealloc"
Nam Cao <namcao@linutronix.de> says:
The debug_pagealloc feature is not functional on RISCV. With this feature
enabled (CONFIG_DEBUG_PAGEALLOC=y and debug_pagealloc=on), kernel crashes
early during boot.
QEMU command that can reproduce this problem:
qemu-system-riscv64 -machine virt \
-kernel Image \
-append "console=ttyS0 root=/dev/vda debug_pagealloc=on" \
-nographic \
-drive "file=root.img,format=raw,id=hd0" \
-device virtio-blk-device,drive=hd0 \
-m 4G \
This series makes debug_pagealloc functional.
* b4-shazam-merge:
riscv: rewrite __kernel_map_pages() to fix sleeping in invalid context
riscv: force PAGE_SIZE linear mapping if debug_pagealloc is enabled
