GSMI driver uses dma_pool_* API functions for buffer allocation
because it requires that the SMI buffers are allocated within 32-bit
physical address space. However, this does not work well with IOMMU
since there is no real device and hence no domain associated with the
device.

The ether_setup function adds the IFF_TX_SKB_SHARING flag to the

The struct irq_info of Xen's event handling is used only for two
evtchn_ops functions outside of events_base.c. Those two functions
can easily be switched to avoid that usage.
This allows to make struct irq_info and its related access functions
private to events_base.c.

Do some cleanups in Xen event handling code.
Juergen Gross (5):
xen: remove no longer used functions
xen/events: make struct irq_info private to events_base.c
xen/events: only register debug interrupt for 2-level events
xen/events: unmask a fifo event channel only if it was masked
Docume
Unmasking an event channel with fifo events channels being used can
require a hypercall to be made, so try to avoid that by checking
whether the event channel was really masked.

The ether_setup function adds the IFF_TX_SKB_SHARING flag to the
device. This flag indicates that it is safe to transmit shared skbs to
the device.
However, this is not true for many Ethernet devices. Many Ethernet
drivers would call skb_pad or skb_padto on the transmission path,
which modify the

This patch series adds support for UCI driver. UCI driver enables userspace
clients to communicate to external MHI devices like modem and WLAN. UCI driver
probe creates standard character device file nodes for userspace clients to
perform open, read, write, poll and release file operations. These f
Currently this macro is defined in internal MHI header as
a TRE length mask. Moving it to external header allows MHI
