* 'io_remap_pfn_range' of git://www.jni.nu/cris: CRIS: Define io_remap_pfn_range as remap_pfn_range
2010-08-12CRIS: Define io_remap_pfn_range as remap_pfn_rangeJesper Nilsson
CRIS don't need any special mapping for io, but didn't define this, meaning that all uses of io_remap_pfn_range lead to compile errors. This fixes a compile error introduced in CRIS when drivers/mtd/mtdchar.c mmap handling was changed in commit dd02b67d5e9e7896891fa27eb5db65f55a290998 Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
2010-08-11dma-mapping: remove dma_is_consistent APIFUJITA Tomonori
Architectures implement dma_is_consistent() in different ways (some misinterpret the definition of API in DMA-API.txt). So it hasn't been so useful for drivers. We have only one user of the API in tree. Unlikely out-of-tree drivers use the API. Even if we fix dma_is_consistent() in some architectures, it doesn't look useful at all. It was invented long ago for some old systems that can't allocate coherent memory at all. It's better to export only APIs that are definitely necessary for drivers. Let's remove this API.

2010-08-11dma-mapping: unify dma_get_cache_alignment implementationsFUJITA Tomonori
dma_get_cache_alignment returns the minimum DMA alignment. Architectures defines it as ARCH_DMA_MINALIGN (formally ARCH_KMALLOC_MINALIGN). So we can unify dma_get_cache_alignment implementations. Note that some architectures implement dma_get_cache_alignment wrongly. dma_get_cache_alignment() should return the minimum DMA alignment. So fully-coherent architectures should return 1. This patch also fixes this issue.

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>
2010-08-10tty: remove remaining Hayes ESP ioctlsGreg Kroah-Hartman
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.
