* i2c-core: Make some code staticAdrian Bunk2007-10-13
| | | | | | | After the i2c-isa removal some code can become static. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c: New-style devices can support driver model wakeup flagsDavid Brownell2007-10-13
| | | | | | | | | | We need to be able to flag I2C devices, such as RTCs, which can issue wake events (usually through IRQ lines). This adds an i2c_board_info.flags bit, and uses it to initialize the i2c device node. (And shrinks a few lines that were overly long.)

* i2c: Kill struct i2c_device_idJean Delvare2007-10-13
| | | | | | | | | | I2C devices do not have any form of ID as PCI or USB devices have. No driver uses "MODULE_DEVICE_TABLE(i2c, ...)" because it doesn't make sense. So we can get rid of struct i2c_device_id and the associated support code. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Greg KH <greg@kroah.com>

Set it in au1xxx-ide, amd74xx, cs5530, cs5535, pdc202xx_new, sc1200, pmac and via82cxxx host drivers. * Add IDE_HFLAG_NO_SET_MODE host flag to indicate the need to completely skip programming of host/device for the transfer mode ("smart" hosts). Set it in it821x host driver and check it in ide_tune_dma(). * Add ide_set_pio_mode()/ide_set_dma_mode() helpers and convert all direct ->set_pio_mode/->speedproc users to use these helpers. * Move ide_config_drive_speed() calls from ->set_pio_mode/->speedproc methods to callers. * Rename ->speedproc method to ->set_dma_mode, make it void and update all implementations accordingly. * Update ide_set_xfer_rate() comments. * Unexport ide_config_drive_speed(). v2: * Fix issues noticed by Sergei: - export ide_set_dma_mode() instead of moving ->set_pio_mode abuse wrt to setting DMA modes from sc1200_set_pio_mode() to do_special() - check IDE_HFLAG_NO_SET_MODE in ide_tune_dma() - check for (hwif->set_pio_mode) == NULL in ide_set_pio_mode() - check for (hwif->set_dma_mode) == NULL in ide_set_dma_mode() - return -1 from ide_set_{pio,dma}_mode() if ->set_{pio,dma}_mode == NULL - don't set ->set_{pio,dma}_mode on it821x in "smart" mode - fix build problem in pmac.c - minor fixes in au1xxx-ide.c/cs5530.c/siimage.c - improve patch description Changes in behavior caused by this patch: - HDIO_SET_PIO_MODE ioctl would now return -ENOSYS for attempts to change PIO mode if it821x controller is in "smart" mode - removal of two debugging printk-s (from cs5530.c and sc1200.c) - transfer modes 0x00-0x07 passed from user space may be programmed twice on the device (not really an issue since 0x00 is not supported correctly by any host driver ATM, 0x01 is not supported at all and 0x02-0x07 are invalid) Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

This results in the following changes in behavior: - pre-EIDE SWDMA modes are now also respected - drive->autodma is checked instead of hwif->autodma (doesn't really matter as icside sets both to "1") * Make ide-dma.c::__ide_dma_good_drive() static and drop "__" prefix.

Since for IDE PMAC host driver IDE_CONTROL_REG is always true, device's ->quirk_list is always zero and ->ide_dma_host_{on,off} are nops than the only changes in behavior are: * if PIO mode is set then ->dma_off_queitly is called to disable DMA * if setting transfer mode fails ide_dump_status() is called to dump status v2: * IDE PMAC controllers allow separate PIO and DMA timings and PPC userland depends on this fact, and calls "hdparm -p" without calling "hdparm -d". Therefore to compensate for DMA being disabled by ide_config_drive_speed() for PIO modes: - add IDE_HFLAG_SET_PIO_MODE_KEEP_DMA flag and set it in PMAC host driver - add handling of the new flag to ide-io.c::do_special() Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

The only change in the functionality is that the function now fails if after 20 sec (WAIT_CMD) device is still busy (BUSY_STAT bit is set) while previously instead of failing the function continued with checking for the correct device status (which would give the device additional 10 usec to clear BUSY_STAT bit). * Remove stale comment for ide_config_drive_speed(). * Remove duplicate comment for ide_wait_stat() from <linux/ide.h>.

| * | | | [MTD] [NOR] fix ctrl-alt-del can't reboot for intel flash bugKevin Hao2007-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we press ctrl-alt-del,kernel_restart_prepare will invoke cfi_intelext_reboot which will set flash to read array mode, but later when device_shutdown is invoked which may put current work queue to sleep and other process may be scheduled to running and programming flash in not FL_READY mode again. So we can't boot up if this flash is used for bootloader. Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

| * | | | [JFFS2] Handle dirents on the flash with embedded zero bytes in names.David Woodhouse2007-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In three places: summary scan, normal scan, REF_PRISTINE GC. Just truncate at the NUL, since that was the correct thing to do in the only case where this (inexplicable) breakage has been seen. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
| * | | | [JFFS2] Check for creation of dirents with embedded zero bytes in name.David Woodhouse2007-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have no idea how this happened, but OLPC trac #4184 suggests that it did. Catch it early. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

| * | | | [JFFS2] Check whether garbage-collection actually obsoleted its victim.David Woodhouse2007-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In OLPC trac #4184 we found a case where a corrupted node didn't actually get obsoleted when we tried to garbage-collect it. So we wrote out many million copies of it, in repeated attempts to obsolete it, until the flash became full. Don't Do That. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of matching resv_blocks_gcmerge, which is only about 3, instead match resv_blocks_gctrigger, which includes a proportion of the total device size. These ought to become tunable from userspace, at some point. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
