2010-08-10x86: fix up system call numbering nitLinus Torvalds
As pointed out by Jiri Slaby: when I resolved the the 32-bit x85 system call entry tables for prlimit (due to the conflict with fanotify), I forgot to add the numbering in comments that we do for every fifth entry.

2010-08-10USB: s3c-hsotg: Add initial detection and setup for dedicated FIFO modeBen Dooks
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 fixes a regression due to the new apb_pclk stuff in the U300 platform, makes it run by splitting the apb clock off the single UART clocks. For the MMCI and PL022 clocks we don't split them: these are actually hardwired to the same clock terminal and will thus simply have a double reference count and will be referenced twice. We also move clock registration to .init_irq() so they are available early enough for probing to be successful and remove the earlier quirk to clock primecells during PrimeCell registration.

2010-08-10tty: Add EXTPROC support for LINEMODEhyc@symas.com
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: http://anonsvn.mit.edu/viewvc/krb5/trunk/src/appl/telnet/?pathrev=17741 Signed-off-by: Howard Chu <hyc@symas.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

This cleans up the remaining arch-specific locations of this ioctl value. Thanks to Arnd for pointing these out.

PROC_MM doesn't exist in Kconfig. Looking around it looks like a left-over from 2.6.0 or even 2.4 times, last mentioned in a fedora patch for 2.6.10.

2010-08-09alpha: implement HW performance events on the EV67 and later CPUsMichael Cree
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.

2010-08-09alpha: add performance monitor interrupt counterMichael Cree
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!

2010-08-09kmap_atomic: make kunmap_atomic() harder to misuseCesar Eduardo Barros
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 *?

2010-08-09mm: provide init_mm mm_context initializerHeiko Carstens
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.
