I hit this on 3.13-rc7 while transferring data over an ASIX88179 USB 3
to gigabit ethernet adapter, transferring data at only 4MB/s.
What other debug options apart from SG debug would be useful here?
Thanks,

PROC_FS is a bool, so this code is either present or
absent. It will never be modular, so using module_init

Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this,
we'd have to add module.

Many devices rely on pinctrl/pinmux settings being applied
before probing and some of these may probe before device_initcall
time (e.g. i2c at subsys_initcall). Move Tegra1x4 pinctrl driver
registration to arch_initcall time so that proper pin settings
can be applied earlier.

At boot time, UEFI runtime support needs to call into the UEFI firmware
to switch to a virtual address map. This call must be made with UEFI
memory regions identity mapped. The exisitng early boot code creates
an identity map of kernel text/data but this is not sufficient for UEFI.
This patch adds
Add explanation of arm64 EFI stub and kernel image header changes
needed to masquerade as a PE/COFF application.

The following series implements a fix for:
A kdump problem about DMA that has been discussed for a long time. That is,
when a kernel panics and boots into the kdump kernel, DMA started by the
panicked kernel is not stopped before the kdump kernel is booted and the

Most of the code for Crashdump Accepting Active IOMMU is contained

and device-driver initialization

This patch contains a function to print the hardware registers of each

This function seemed far too useful to leave out.

The srm console is always built in. It will never be modular,
so using module_init as an alias for __initcall is rather
misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modula

The issue is that when you touch 1 byte of an untouched, contiguous 2MB
