When working with DRAM MMU, we should supply the userspace with the virtual start address of the DRAM instead of the physical one.

2021-01-26VMCI: Enforce queuepair max size for IOCTL_VMCI_QUEUEPAIR_ALLOCJorgen Hansen
When create the VMCI queue pair tracking data structures on the host side, the IOCTL for creating the VMCI queue pair didn't validate the queue pair size parameters. This change adds checks for this. This avoids a memory allocation issue in qp_host_alloc_queue, as reported by nslusarek@gmx.net. The check in qp_host_alloc_queue has also been updated to enforce the maximum queue pair size as defined by VMCI_MAX_GUEST_QP_MEMORY.

The K: entry should ensure that Nick and I always get CC'd on patches that touch these files but it is better to be explicit rather than implicit.

2021-01-24proc_sysctl: fix oops caused by incorrect command parametersXiaoming Ni
The process_sysctl_arg() does not check whether val is empty before invoking strlen(val). If the command line parameter () is incorrectly configured and val is empty, oops is triggered. For example: "hung_task_panic=1" is incorrectly written as "hung_task_panic", oops is triggered. The call stack is as follows: Kernel command line: .... hung_task_panic ...... Call trace: __pi_strlen+0x10/0x98 parse_args+0x278/0x344 do_sysctl_args+0x8c/0xfc kernel_init+0x5c/0xf4 ret_from_fork+0x10/0x30 To fix it, check whether "val" is empty when "phram" is a sysctl field. Error codes are returned in the failure branch, and error logs are generated by parse_args().
