2010-06-04omap: remove BUG_ON for disabled interruptsCory Maccarrone
Remove a BUG_ON for when interrupts are disabled during an MMC request. During boot, interrupts can be disabled when a request is made, causing this bug to be triggered. In reality, there's no reason this should halt the kernel, as the driver has proved reliable in spite of disabled interrupts, and additionally, there's nothing in this code that would require interrupts to be enabled. The only setup I've managed to make it trigger on is on the HTC Herald during bootup when the driver is built into the kernel (mostly because that's all I have). I believe it's related to the fact that on bootup I get many timeout errors on "CMD5" while initializing the card. Each CMD5 timeout triggers that bug (I changed it to a WARN_ON to get it to boot in) due to the fact that part of the timeout code involves sending the request again. With interrupts turned off, that BUG would be triggered.

2010-06-04fbdev: fix frame buffer devices menuThadeu Lima de Souza Cascardo
Commit f601441916d1e19291d0b4f044b4a7551e2924d0 ("imxfb: add support for i.MX25:) has inserted the symbol HAVE_FB_IMX, which does not depend on FB after the menuconfig FB. This breaks the menu, presenting most of the drivers outside of it, when using menuconfig. Moving the symbol to the start of the file, just like HAVE_FB_ATMEL, fixes the problem without breaking it for iMX25 configurations (tested with ARCH=arm, no build).

This reverts commit 49bbd815fd8ba26d0354900b783b767c7f47c816 ("fb_defio: fix for non-dirty ptes"). Although the fix provided is correct, it's been suggested to avoid the underlying race in the same way as it is currently done in filesystems like NFS, for maintainability. A following patch "fb_defio: redo fix for non-dirty ptes" will provide such an alternate fix.

All calls to "attach" routine share the same static buffer for this name, but the contents will differ on each call (including the comedi device number and the comedi board name). This changes the name displayed in /proc/interrupts for previous calls to request_irq() using the same buffer. Just use the board name instead; it has slightly less information (no comedi device number) but at least it doesn't change over the lifetime of the IRQ handler.

This most likely won't cause problems on systems as people don't typically enable GPIO RTS/CTS if they don't actually use it. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-06-04serial: bfin_5xx: IRDA is not affected by anomaly 05000230Graf Yang
Anomaly 05000230 (over sampling of the UART STOP bit) applies only when the peripheral is operating in UART mode. So drop the anomaly handling when the UART is in IRDA mode.

2010-06-04msm_serial: fix serial on troutAbhijeet Dharmapurikar
Set the mnd counter based on uartclk. This fixes a problem on 7x30 where the uartclk is 19.2Mhz rather than the usual 4.8Mhz. Trout incorrectly reports uartclk to be running at 19.2Mhz It is actually running at 4.8Mhz. For trout force mnd counter values as if uartclk was fed by tcxo/4.
