2010-08-17Make do_execve() take a const filename pointerDavid Howells
Make do_execve() take a const filename pointer so that kernel_execve() compiles correctly on ARM: arch/arm/kernel/sys_arm.c:88: warning: passing argument 1 of 'do_execve' discards qualifiers from pointer target type This also requires the argv and envp arguments to be consted twice, once for the pointer array and once for the strings the array points to. This is because do_execve() passes a pointer to the filename (now const) to copy_strings_kernel(). A simpler alternative would be to cast the filename pointer in do_execve() when it's passed to copy_strings_kernel(). do_execve() may not change any of the strings it is passed as part of the argv or envp lists as they are some of them in .rodata, so marking these strings as const should be fine. Further kernel_execve() and sys_execve() need to be changed to match. This has been test built on x86_64, frv, arm and mips.

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.

2010-08-11dma-mapping: rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGNFUJITA Tomonori
Now each architecture has the own dma_get_cache_alignment implementation. dma_get_cache_alignment returns the minimum DMA alignment. Architectures define it as ARCH_KMALLOC_MINALIGN (it's used to make sure that malloc'ed buffer is DMA-safe; the buffer doesn't share a cache with the others). So we can unify dma_get_cache_alignment implementations. This patch: dma_get_cache_alignment() needs to know if an architecture defines ARCH_KMALLOC_MINALIGN or not (needs to know if architecture has DMA alignment restriction). However, slab.h define ARCH_KMALLOC_MINALIGN if architectures doesn't define it. Let's rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGN. ARCH_KMALLOC_MINALIGN is used only in the internals of slab/slob/slub (except for crypto).

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.

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 *?

2010-08-09remove inode_setattrChristoph Hellwig
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.

2010-08-06powerpc/5200: add mpc5200_psc_ac97_gpio_resetEric Millbrandt
Work around a silicon bug in the ac97 reset functionality of the mpc5200(b). The implementation of the ac97 "cold" reset is flawed. If the sync and output lines are high when reset is asserted the attached ac97 device may go into test mode. Avoid this by reconfiguring the psc to gpio mode and generating the reset manually. From MPC5200B User's Manual: "Some AC97 devices goes to a test mode, if the Sync line is high during the Res line is low (reset phase). To avoid this behavior the Sync line must be also forced to zero during the reset phase. To do that, the pin muxing should switch to GPIO mode and the GPIO control register should be used to control the output lines."

2010-08-05kgdb,powerpc: Replace hardcoded offset by BREAK_INSTR_SIZEMichal Simek
kgdb_handle_breakpoint checks the first arch_kgdb_breakpoint which is not known by gdb that's why is necessary jump over it. The jump lenght is equal to BREAK_INSTR_SIZE that's why is cleaner to use defined macro instead of hardcoded non-described offset.

2010-08-04powerpc/8xx: Add support for the MPC8xx based boards from TQCHeiko Schocher
Supported SMC1 (serial console), SCC1 Ethernet (10Mbps HD). FEC Ethernet, 8MB NOR CFI Flash. Tested on STK8xx with TQM860L (with FEC) and with TQM855M (without FEC). Signed-off-by: Heiko Schocher <hs@denx.de> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-08-04powerpc/85xx: Introduce support for the Freescale P1022DS reference boardTimur Tabi
Introduce basic support for the Freescale P1022DS reference board, based on the Freescale BSP for this board. This patch excludes the DIU, SSI, and MMC/SD drivers. Only a 36-bit DTS is provided. Update mpc86xx_smp_defconfig and mpc85xx_defconfig to support the P1022DS. This means enabling 64-bit physical address support, increasing the maximum zone order to 12 (to allow the DIU driver to allocate large chunks), and clean up the audio options to disable the deprecated OSS support.

2010-08-04powerpc/85xx: Adding DTS for the STx GP3-SSA MPC8555 boardBradley Hughes
This version uses "fsl,mpc8555..." instead of "fsl,85..." notation. There is also an 8541 version of this board so DTS for this board is specific to the 8555 processor. Another patch is coming to fix-up other DTS that use old notation. Signed-off-by: Bradley Hughes <bhughes@silicontkx.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2010-08-04powerpc/tqm85xx: add a quirk for ti1520 PCMCIA bridgeDmitry Eremin-Solenikov
By default ti1520 bridge expects an input clock on CLOCK pin (to control power chip). However on this boards CLOCK should be generated by PCI1520 itself. Add a quirk that enables internal 16 KHz clock generation on this pin. Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2010-08-04powerpc/85xx: Cleanup QE initialization for MPC85xxMDS boardsAnton Vorontsov
The mpc85xx_mds_setup_arch() function is incomprehensible and unmaintainable. Factor out all QE specific stuff into mpc85xx_mds_qe_init() and mpc85xx_mds_reset_ucc_phys(). Also move QE stuff out of mpc85xx_mds_pic_init(). The diff is unreadable, but only because the code was so. ;-) It should be better now, and less indented.

2010-08-04powerpc/85xx: Fix booting for P1021MDS boardsAnton Vorontsov
P1021 processors have no dedicated ROM to store the QE microcode, so the fimrware is stored externally, and it is U-Boot responsibility to load it. It might be that the board is booting without QE, e.g. currently U-Boot doesn't support QE for P1021MDS boards, which means that QE isn't initialized, and so the board hangs early at boot. This patch fixes the issue by marking QE as disabled and checking the state in the probing code. U-Boot should fixup the state if it initialized the QE.

2010-08-04powerpc/85xx: Fix SWIOTLB initalization for MPC85xxMDS boardsAnton Vorontsov
The code inside '#ifdef CONFIG_QUICC_ENGINE' makes the mpc85xx_mds_setup_arch() return early if no QE nodes present, and so SWIOTLB is never initialized. This patch fixes the issue by moving SWIOTLB code above QE. Signed-off-by: Anton Vorontsov <avorontsov@mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
