Add support for the dedicated FIFO mode on newer SoCs such as the S5PV210
partly to improve support and to fix the bug where any non-EP0 IN endpoint
requires its own FIFO allocation.
To fix this, we ensure that any non-zero IN endpoint is given a TXFIFO
using the same allocation method as the periodic case (all our current
hardware has enough FIFOs and FIFO memory for a 1:1 mapping) and ensure
that the necessary transmission done interrupt is enabled.
The default settings from reset for the core point all EPs at FIFO0,
used for the control endpoint. However, the controller documentation
states that all IN endpoints _must_ have a unique FIFO to avoid any
contention during transmission.
Note, this leaves us with a large IN FIFO for EP0 (which re-uses the
old NPTXFIFO) for an endpoint which cannot shift more than a pair of
packets at a time... this is a waste, but it looks like we cannot
re-allocate space to the individual IN FIFOs as they are already
maxed out (to be confirmed).

This patch is against the 2.6.34 source.
Paraphrased from the 1989 BSD patch by David Borman @ cray.com:
These are the changes needed for the kernel to support
LINEMODE in the server.
There is a new bit in the termios local flag word, EXTPROC.
When this bit is set, several aspects of the terminal driver
are disabled. Input line editing, character echo, and mapping
of signals are all disabled. This allows the telnetd to turn
off these functions when in linemode, but still keep track of
what state the user wants the terminal to be in.
New ioctl:
TIOCSIG Generate a signal to processes in the
current process group of the pty.
There is a new mode for packet driver, the TIOCPKT_IOCTL bit.
When packet mode is turned on in the pty, and the EXTPROC bit
is set, then whenever the state of the pty is changed, the
next read on the master side of the pty will have the TIOCPKT_IOCTL
bit set. This allows the process on the server side of the pty
to know when the state of the terminal has changed; it can then
issue the appropriate ioctl to retrieve the new state.
Since the original BSD patches accompanied the source code for telnet
I've left that reference here, but obviously the feature is useful for
any remote terminal protocol, including ssh.
The corresponding feature has existed in the BSD tty driver since 1989.
For historical reference, a good copy of the relevant files can be found
here:

As Jeff Dike pointed out, the Hayes ESP driver was removed in commit
f53a2ade0bb9f2a81f473e6469155172a96b7c38, so these ioctl definitions
should also be removed. This cleans up the remaining arch-specific
locations of this ioctl value.
Thanks to Arnd for pointing these out.

This implements hardware performance events for the EV67 and later CPUs
within the Linux performance events subsystem. Only using the performance
monitoring unit in HP/Compaq's so called "Aggregrate mode" is supported.
The code has been implemented in a manner that makes extension to other
older Alpha CPUs relatively straightforward should some mug wish to
indulge themselves.

The following patches implement hardware performance events for the Alpha
EV67 and later CPUs. I have had this running on a Compaq XP1000 (EV67,
single CPU) for a few days now. Pretty cool -- discovered that the glibc
exp2() library routine uses on average 985 cycles to execute 777 CPU
instructions whereas Compaq's CPML library version of exp2() uses on
average 32 cycles to execute 47 CPU instructions to achieve the same
thing!
This patch:
Add performance monitor interrupt counternd and export the count to user
space via /proc/interrupts.

kunmap_atomic() is currently at level -4 on Rusty's "Hard To Misuse"
list[1] ("Follow common convention and you'll get it wrong"), except in
some architectures when CONFIG_DEBUG_HIGHMEM is set[2][3].
kunmap() takes a pointer to a struct page; kunmap_atomic(), however, takes
takes a pointer to within the page itself. This seems to once in a while
trip people up (the convention they are following is the one from
kunmap()).
Make it much harder to misuse, by moving it to level 9 on Rusty's list[4]
("The compiler/linker won't let you get it wrong"). This is done by
refusing to build if the type of its first argument is a pointer to a
struct page.
The real kunmap_atomic() is renamed to kunmap_atomic_notypecheck()
(which is what you would call in case for some strange reason calling it
with a pointer to a struct page is not incorrect in your code).
The previous version of this patch was compile tested on x86-64.
[1] http://ozlabs.org/~rusty/index.cgi/tech/2008-04-01.html
[2] In these cases, it is at level 5, "Do it right or it will always
break at runtime."
[3] At least mips and powerpc look very similar, and sparc also seems to
share a common ancestor with both; there seems to be quite some
degree of copy-and-paste coding here. The include/asm/highmem.h file
for these three archs mention x86 CPUs at its top.
[4] http://ozlabs.org/~rusty/index.cgi/tech/2008-03-30.html
[5] As an aside, could someone tell me why mn10300 uses unsigned long as
the first parameter of kunmap_atomic() instead of void *?

Provide an INIT_MM_CONTEXT intializer macro which can be used to
statically initialize mm_struct:mm_context of init_mm. This way we can
get rid of code which will do the initialization at run time (on s390).
In addition the current code can be found at a place where it is not
expected. So let's have a common initializer which architectures
can use if needed.
This is based on a patch from Suzuki Poulose.

Add a flags field to help glibc implementing statvfs(3) efficiently.
We copy the flag values from glibc, and add a new ST_VALID flag to
denote that f_flags is implemented.

We'll need the path to implement the flags field for statvfs support.
We do have it available in all callers except:
- ecryptfs_statfs. This one doesn't actually need vfs_statfs but just
needs to do a caller to the lower filesystem statfs method.
- sys_ustat. Add a non-exported statfs_by_dentry helper for it which
doesn't won't be able to fill out the flags field later on.
In addition rename the helpers for statfs vs fstatfs to do_*statfs instead
of the misleading vfs prefix.

Replace inode_setattr with opencoded variants of it in all callers. This
moves the remaining call to vmtruncate into the filesystem methods where it
can be replaced with the proper truncate sequence.
In a few cases it was obvious that we would never end up calling vmtruncate
so it was left out in the opencoded variant:
spufs: explicitly checks for ATTR_SIZE earlier
btrfs,hugetlbfs,logfs,dlmfs: explicitly clears ATTR_SIZE earlier
ufs: contains an opencoded simple_seattr + truncate that sets the filesize just above
In addition to that ncpfs called inode_setattr with handcrafted iattrs,
which allowed to trim down the opencoded variant.

Change default load address of the initrd in case of IPL from reader.
The new load address is directly behind the kernel image.
This way we can see immediatly if there are any problems with the code
which tries to rescue the initrd in case the bootmem bitmap would
overlap with the initrd.

For whatever reason GCC isn't able to figure things out in
the control flow (in particular when min() and max() expressions
are involved) on sparc as well as it can on x86.
So lots of useless incorrect user copy warnings get spewed and the
full-on compile failure mode of the user copy checks were never usable
on sparc at all.
People can debug these kinds of problems on x86.

After b0f82b81fe6bbcf78d478071f33e44554726bc81 ("perf: Drop the skip
argument from perf_arch_fetch_regs_caller") the build broke on sparc64
due to the lack of a module symbol export of __perf_arch_fetch_caller_regs.
But that assembler helper can actually be complete eliminated now that
the semantics of this interface have been greatly simplified.

Thomas Backlund reported that the powerpc build broke with make 3.82.
It failed with the following message:
