Hi Linus, This is a fix for the rework of ARM's pfn_valid() implementation merged during this merge window. The following changes since commit a180bd1d7e16173d965b263c5a536aa40afa2a2a: iov_iter: remove uaccess_kernel() warning from iov_iter_init() (2021-07-04 16:12:42 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock.git tags/fixes-2021-07-09 for you to fetch changes up to 024591f9a6e0164ec23301784d1e6d8f6cacbe59: arm: ioremap: don't abuse pfn_valid() to check if pfn is in RAM (2021-07-06 09:01:47 +0300) ---------------------------------------------------------------- arm: ioremap: don't abuse pfn_valid() to check if pfn is in RAM The semantics of pfn_valid() is to check presence of the memory map for a PFN and not whether a PFN is in RAM. The memory map may be present for a hole in the physical memory and if such hole corresponds to an MMIO range, __arm_ioremap_pfn_caller() will produce a WARN() and fail: Use memblock_is_map_memory() instead of pfn_valid() to check if a PFN is in RAM or not. ---------------------------------------------------------------- Mike Rapoport (1): arm: ioremap: don't abuse pfn_valid() to check if pfn is in RAM arch/arm/mm/ioremap.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) -- Sincerely yours, Mike.
