x86 boot: add code to add BIOS provided EFI memory entries to kernel
Add to the kernels boot memory map 'memmap' entries found in
the EFI memory descriptors passed in from the BIOS.
On EFI systems, up to E820MAX == 128 memory map entries can
be passed via the legacy E820 interface (limited by the size
of the 'zeropage'). These entries can be duplicated in the
EFI descriptors also passed from the BIOS, and possibly more
entries passed by the EFI interface, which does not have the
E820MAX limit on number of memory map entries.
This code doesn't worry about the likely duplicate, overlapping
or (unlikely) conflicting entries between the EFI map and the
E820 map. It just dumps all the EFI entries into the memmap[]
array (which already has the E820 entries) and lets the existing
routine sanitize_e820_map() sort the mess out.

The map size counter passed into, and back out of, sanitize_e820_map(),

legacy BIOS E820 structures. This patch changes that type to an 'int',

of course does not change; that remains at 8 bits for this count, holding

when those additional memory map entries are passed from the BIOS via

x86 boot: proper use of ARRAY_SIZE instead of repeated E820MAX constant
This patch is motivated by a subsequent patch which will allow for more
memory map entries on EFI supported systems than can be passed via the x86
legacy BIOS E820 interface. The legacy interface is limited to E820MAX ==
128 memory entries, and that "E820MAX" manifest constant was used as the
size for several arrays and loops over those arrays.
The primary change in this patch is to change code loop sizes over those
arrays from using the constant E820MAX, to using the ARRAY_SIZE() macro
evaluated for the array being looped. That way, a subsequent patch can
change the size of some of these arrays, without breaking this code.
This patch also adds a parameter to the sanitize_e820_map() routine,
which had an implicit size for the array passed it of E820MAX entries.
This new parameter explicitly passes the size of said array. Once again,
this will allow a subsequent patch to change that array size for some
calls to sanitize_e820_map() without breaking the code.
As part of enhancing the sanitize_e820_map() interface this way, I further
combined the unnecessarily distinct x86_32 and x86_64 declarations for
this routine into a single, commonly used, declaration.
This patch in itself should make no difference to the resulting kernel
binary.

tcp: TCP connection times out if ICMP frag needed is delayed
We are seeing an issue with TCP in handling an ICMP frag needed
message that is received after net.ipv4.tcp_retries1 retransmits.
The default value of retries1 is 3. So if the path mtu changes
and ICMP frag needed is lost for the first 3 retransmits or if
it gets delayed until 3 retransmits are done, TCP doesn't update
MSS correctly and continues to retransmit the orginal message
until it timesout after tcp_retries2 retransmits.
I am seeing this issue even with the latest 2.6.25.4 kernel.
In tcp_retransmit_timer(), when retransmits counter exceeds
tcp_retries1 value, the dst cache entry of the socket is reset.
At this time, if we receive an ICMP frag needed message, the
dst entry gets updated with the new MTU, but the TCP sockets
dst_cache entry remains NULL.
So the next time when we try to retransmit after the ICMP frag
needed is received, tcp_retransmit_skb() gets called. Here the
cur_mss value is calculated at the start of the routine with
a NULL sk_dst_cache. Instead we should call tcp_current_mss after
the rebuild_header that caches the dst entry with the updated mtu.
Also the rebuild_header should be called before tcp_fragment
so that skb is fragmented if the mss goes down.

USB: serial: ch341: New VID/PID for CH341 USB-serial
Recent USB-serial devices using the WinChipHead CH340/CH341 chipset are
being shipped with a new vendor/product ID code pair, but an otherwise
identical device. (This is confirmed by looking at INF for the included
Windows driver.)
Patch is tested and working, both with new and old devices.

USB: add TELIT HDSPA UC864-E modem to option driver
This adds the Telit UC864-E HDSPA modem support to the option driver.
This lets their customers comply with the GPL instead of having to use a
binary driver from the manufacturer.

usb-serial: Use ftdi_sio driver for RATOC REX-USB60F
This patch reverts 57833ea6b95a3995149f1f6d1a8d8862ab7a0ba2
("usb-serial: pl2303: add support for RATOC REX-USB60F") and adds
support for the device to ftdi_sio driver.
There is a race from when a device is created with device_create() and
then the drvdata is set with a call to dev_set_drvdata() in which a
sysfs file could be open, yet the drvdata will be NULL, causing all
sorts of bad things to happen.
This patch fixes the problem by using the new function,
device_create_drvdata(). It fixes the problem in all of the scsi
drivers that need it.
