Alan pointed out a race in the code where hvc_remove is invoked. The
recent virtio_console work is the first user of hvc_remove().
Alan describes it thus:
The hvc_console assumes that a close and remove call can't occur at the
same time.
In addition tty_hangup(tty) is problematic as tty_hangup i

Hi all,
I recently posted a patch which improves the baud rate calculation on the
mpc5200b. Following requests by Grant and Wolfram, I added changes which do
also affect the mpc512x.
Unfortunately, I don't have access to such a system, but IMHO the code (both

Let the Nintendo Wii gaming console use per-device dma coherent allocations.
This will be used later by some of its drivers.

The HCD_NO_COHERENT_MEM USB host controller driver flag can be enabled
to instruct the USB stack to avoid allocating coherent memory for USB
buffers.
This flag is useful to overcome some esoteric memory access restrictions
found in some platforms.

Some of the devices in the "Hollywood" chipset of the Nintendo Wii video
game console have restrictions performing DMA transfers to the first
contiguous RAM region (known as MEM1).
For example, up to 3 bytes of the last word of a DMA transfer of a
non-32 bit aligned length to MEM1 may be lost.
Such
Split unmap_urb_for_dma() and map_urb_for_dma() into smaller pieces
to make the code easier to read and maintain.
This patch adds four new URB flags which are used by map_urb_for_dma()
to mark URBs with the exact method used to map the setup packet and/or the
transfer buffer.
These flags are check
The current SWIOTLB code uses a default of 64MB for the IO TLB area.
This size can be influenced using a kernel command line parameter "swiotlb".
Unfortunately, the parsing of the kernel command line is done _after_ the
swiotlb is initialized on some architectures.
This patch adds a new function s
The current SWIOTLB code does not support NOT_COHERENT_CACHE platforms.
This patch adds support for NOT_COHERENT_CACHE platforms to SWIOTLB by
adding two platform specific functions swiotlb_dma_sync_page() and
swiotlb_dma_sync() which can be used to explicitly manage cache coherency.
On PowerPC th
This patch makes swiotlb_alloc_boot() available again.
This weak function can be overloaded to modify slightly how the SWIOTLB

This will be used later to support the Nintendo Wii video game console,

This patch adds min_direct_dma_addr to struct dev_archdata.
min_direct_dma_addr can be used to define which is the minimum address
suitable for a DMA operation.
dma_capable() is updated to use this information in the SWIOTLB case.
This will be used later to support the Nintendo Wii video game con
