This patch adds basic sanity tests to ensure that the instruction patching

original virtual address based checks, and this simplifies the code a bit.

A PCI-Express non-transparent bridge (NTB) is a point-to-point PCIe bus
connecting 2 systems, providing electrical isolation between the two
subsystems.
A non-transparent bridge is functionally similar to a transparent

Please also remove the MODULE_ARCH_VERMAGIC_P2V entirely from module.h
The device(H/W controller) need to access few special memory
blocks(IOVA==PA) and DRAM as well.
OK, so only /some/ of the VA space is VA==PA, and some is remapped; that's a
little different that what you originally implied above.
BTW, which HW module is this; AVP/COP or something else.

Hi Tejun,
Actually I want to make parallelization of one task into three tasks.
Therefore I created three single threaded work queues means divide the
task into three tasks. You are right that I can use one work queue as
well. But when I am doing three times schedule on different work
queues, I

This patch fixes the initrd setup code to use phys_addr_t instead of assuming
32-bit addressing. Without this we cannot boot on systems where initrd is
located above the 4G physical address limit.
On small systems (e.g. embedded ones) IP addresses are often configured
by bootloaders and get assigned to kernel via parameter ip=. If set to
ip=dhcp, even nameserver entries from DHCP daemons are handled. These
entries exported in /proc/net/pnp are commonly linked by /etc/resolv.conf.

This patch adds load_avg_ratio to each task. The load_avg_ratio is a
variant of load_avg_contrib which is not scaled by the task priority. It
is calculated like this:
runnable_avg_sum * NICE_0_LOAD / (runnable_avg_period + 1).

This patch modifies the switch_mm() processor functions to use phys_addr_t.
On LPAE systems, we now honor the upper 32-bits of the physical address that
