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).Signed-off-by: Ben Dooks

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:

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.

[5] As an aside, could someone tell me why mn10300 uses unsigned long as
the first parameter of kunmap_atomic() instead of void *?Signed-off-by: Cesar Eduardo Barros

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.

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 aboveIn addition to that ncpfs called inode_setattr with handcrafted iattrs,
which allowed to trim down the opencoded variant.Signed-off-by: Christoph Hellwig
