From facc68516a7ee6d4992dc47b42b47c600b20b21d Mon Sep 17 00:00:00 2001 From: Bruce Rogers Date: Thu, 30 Jul 2020 07:05:19 -0600 Subject: [PATCH] virtio-mem: Correct format specifier mismatch for RISC-V This likely affects other, less popular host architectures as well. Less common host architectures under linux get QEMU_VMALLOC_ALIGN (from which VIRTIO_MEM_MIN_BLOCK_SIZE is derived) define to a variable of type uintptr, which isn't compatible with the format specifier used to print a user message. Since this particular usage of the underlying data seems unique to this file, the simple fix is to just cast QEMU_VMALLOC_ALIGN to uint32_t, which corresponds to the format specifier used.
