Commit "x86: make config_irqsrc not MPspec specific" introduced some uses
of uninitialized fields in mp_config_acpi_legacy_irqs(). I need the
following patch to get sched-devel/master to boot.

69c9189320 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.

6e9bcc796b x86 boot: change sanitize_e820_map parameter from byte to int to allow bigger memory maps
The map size counter passed into, and back out of, sanitize_e820_map(),
was an eight bit type (char or u8), as derived from its origins in
legacy BIOS E820 structures.  This patch changes that type to an 'int',
to allow this sanitize routine to also be used on larger maps (larger
than the 256 count that fits in a char).  The legacy BIOS E820 interface
of course does not change; that remains at 8 bits for this count, holding
up to E820MAX == 128 entries.  But the kernel internals can handle more
when those additional memory map entries are passed from the BIOS via
EFI interfaces.

028b785888 x86 boot: extend some internal memory map arrays to handle larger EFI input
Extend internal boot time memory tables to allow for up to
three entries per node, which may be larger than the 128 E820MAX
entries handled by the legacy BIOS E820 interface.  The EFI
interface, if present, is capable of passing memory map
entries for these larger node counts.

This patch requires an earlier patch that rewrote code depending
on these array sizes from using E820MAX explicitly to size loops,
to instead using ARRAY_SIZE() of the applicable array.

Another patch following this one will provide the code to pick
up additional memory entries passed via the EFI interface from
the BIOS and insert them in the following, now enlarged, arrays.

c3965bd151 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.

c801ed3860 x86 boot: simplify pageblock_bits enum declaration
The use of #defines with '##' pre-processor concatenation is a useful
way to form several symbol names with a common pattern.  But when there
is just a single name obtained from that #define, it's just obfuscation.
Better to just write the plain symbol name, as is.

The following patch is a result of my wasting ten minutes looking through
the kernel to figure out what 'PB_migrate_end' meant, and forgetting what
I came to do, by the time I figured out that the #define PB_range macro
defined it.

- setup_memory_map() and finish_e820_parsing() are
factored out from setup_arch(), and declarations
are added to e820_32.h.

- print_memory_map() is made static and removed from
e820_32.h.

- user_defined_memmap is marked as __initdata.

14d2c68baa sparc64: Fix stack tracing through trap frames.
The offset to the pt_regs area was wrong, so we weren't
looking at the right location for the magic cookie.

A trap frame is composed of a "struct sparc_stackf" then
a "struct pt_regs", the code was using "struct reg_window"
instead of "struct sparc_stackf".

a051bc5bb1 sparc64: Fix kernel thread stack termination.
Because of the silly way I set up the initial stack for
new kernel threads, there is a loop at the top of the
stack.

To fix this, properly add another stack frame that is copied
from the parent and terminate it in the child by setting
the frame pointer in that frame to zero.

071f92d059 net: The world is not perfect patch.
Unless there will be any objection here, I suggest consider the
following patch which simply removes the code for the
-DI_WISH_WORLD_WERE_PERFECT in the three methods which use it.

The compilation errors we get when using -DI_WISH_WORLD_WERE_PERFECT
show that this code was not built and not used for really a long time.

4b74944044 tcp: Make prior_ssthresh a u32
If previous window was above representable values of u16,
strange things will happen if undo with the truncated value
is called for. Alternatively, this could be fixed by some
max trickery but that would limit undoing high-speed undos.

Adds 16-bit hole but there isn't anything to fill it with.

The crypto layer will determine whether that is valid
or not.

51f82a2b12 net/ipv4/arp.c: Use common hex_asc helpers
Here the local hexbuf is a duplicate of global const char hex_asc from
lib/hexdump.c, except the hex letters' cases:

	const char hexbuf[] = "0123456789ABCDEF";

	const char hex_asc[] = "0123456789abcdef";

and here to print HW addresses, the hex cases are not significant.

Thanks to Harvey Harrison to introduce the hex_asc_hi/hex_asc_lo helpers.

b1443e2f65 cassini: Only use chip checksum for ipv4 packets.
According to David Monro, at least with Natsemi Saturn chips the
cassini driver has some trouble with ipv6 checksums.

Until we have more information about what's going on here, only
use the chip checksums for ipv4.

This workaround was suggested and tested by David.

Update version and release date.

337e3c48e9 provide out-of-line strcat() for m68k
Whether we sidestep it in init/main.c or not, such situations
will arise again; compiler does generate calls of strcat()
on optimizations, so we really ought to have an out-of-line
version...
