All devm functions has a device structure as the first argument which is
required by dev_{err,info,dbg} printing functions.
This patch converts pr_err to dev_err as dev_* is preferred after calls
to devm functions.

According to errata i870, access to the PCIe slave port
that are not 32-bit aligned will result in incorrect mapping

Accessing non 32-bit aligned data causes incorrect data in the target

Modify vmalloc_fault() to handle additional page table level.
With 4-level paging, copying happens on p4d level, as we have pgd_none()
always false if p4d_t is folded.

This experimental slow mode support code simply extends the MID/RID value
to allow encoding a 4-bit value in bit 8-11 to specify the SLM bit value.
With this value set the channel associated with the device will be processed
slower by the hardware. The idea is that the slow mode

The priority handling uses MID/RID values to determine if channels
below to RX or TX sides. The case of RX is unchanged and as low channel
number as possible is used to ensure high priority. New with this code
is that TX is allocated with highest channel number first to force lo

The new syscall statx is implemented as generic code, so enable it
for architectures like openrisc which use the generic syscall table.
