On 10.11.22 16:45, Ross Philipson wrote: There are a number of places where early_memremap is called but the return pointer is not checked for NULL. The call can result in a NULL being returned so the checks must be added. Note that the maintainers for both the Jailhouse and Xen code approved of using panic() to handle allocation failures. In addition to checking the return values, a bit of extra cleanup of pr_* usages was done since the pr_fmt macro was introduced in the modules touched by this patch.
