2016-12-05atm: fix improper return valuePan Bian
It returns variable "error" when ioremap_nocache() returns a NULL pointer. The value of "error" is 0 then, which will mislead the callers to believe that there is no error.

2016-12-05atm: lanai: set error code when ioremap failsPan Bian
In function lanai_dev_open(), when the call to ioremap() fails, the value of return variable result is 0. 0 means no error in this context.

2016-05-31atm: firestream: add more reserved stringsDan Carpenter
This bug was there when the driver was first added in back in year 2000.

I added them as reserved 37 to reserved 40. It's possible that strings are really supposed to be added in the middle instead of at the end, but this approach is safe, in that it fixes the bug and doesn't break anything that wasn't already broken.

2015-09-17solos-pci: Increase headroom on received packetsDavid Woodhouse
A comment in include/linux/skbuff.h says that: * Various parts of the networking layer expect at least 32 bytes of * headroom, you should not reduce this. This was demonstrated by a panic when handling fragmented IPv6 packets: http://marc.info/?l=linux-netdev&m=144236093519172&w=2 It's not entirely clear if that comment is still valid — and if it is, perhaps netif_rx() ought to be enforcing it with a warning. But either way, it is rather stupid from a performance point of view for us to be receiving packets into a buffer which doesn't have enough room to prepend an Ethernet header — it means that *every* incoming packet is going to be need to be reallocated.
