2012-03-08staging: android: ram_console: fix crash in ram_console_late_initColin Cross
If the persistent ram buffer is not available, ram_console_late_init would crash when dereferencing ram_console_zone. Return early if ram console was not initialized.

2012-03-08staging: android: persistent_ram: handle reserving and mapping memoryColin Cross
Replace the ioremapped memory passed in from the drivers with a memblock_reserve and vmap. Adds a new function, persistent_ram_early_init, designed to be called from the machine init_early callback, that calls memblock_remove and saves the provided persistent ram area layout. Drivers only pass in their struct device * and ecc settings. Locating and mapping the memory is now handled entirely within persistent_ram. Also, convert ram_console to the new persistent_ram_init parameters that only take a struct device * and ecc settings. [jstultz: Fix pr_info casting issues on 64bit, folded two patches as the build breaks if they are apart. Also replaced phys_to_page() w/ pfn_to_page(addr>>PAGE_SHIFT), as phys_to_page is only on a few arches.] CC: Greg KH <gregkh@linuxfoundation.org> CC: Android Kernel Team <kernel-team@android.com> Signed-off-by: Colin Cross <ccross@android.com> Signed-off-by: John Stultz <john.stultz@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-03-08staging: android: ram_console: split out persistent ramColin Cross
Split ram_console into two halves. persistent_ram is a set of apis that handle a block of memory that does not get erased across a reboot. It provides functions to fill it as a single buffer or a ring buffer, and to extract the old data after a reboot. It handles ecc on the data to correct bit errors introduced during reboot. ram_console is now a small wrapper around persistent_ram that feeds console data into the ringbuffer, and exports the old data to /proc/last_kmsg after a reboot.

2012-03-08[media] smsdvb: fix get_frontendGianluca Gennari
In the get_frontend function, an internal copy of the dtv_frontend_properties struct (which is never initialized) is copied over the frontend property cache data structure, resetting everything to 0. In particular, the delivery system is reset to 0 (which is an invalid value) so the driver stops working as soon as a DVBv3 application calls the get_frontend function, giving this error: dvb_frontend_ioctl_legacy: doesn't know how to handle a DVBv3 call to delivery system 0 This patch eliminates the unused internal copy of the dtv_frontend_properties struct, and gives a proper implementation of the get_frontend function. The original author of the patch is Panagiotis Malakoudis, who also tested this new version on Ubuntu 11.10 with the latest media_build tree installed. The original patch has been used on MIPS set-top-boxes for over one year, but it was never posted on the linux-media list. I ported the code to the current media_build tree (converting it to use the dtv_frontend_properties struct) and added basic support for ISDB-T (untested).

2012-03-07ctcm: use correct idal word list for ctcmpcBelinda Thompson
Communication Server Linux uses the ctcmpc code of the ctcm driver. Sending problems have shown up caused by a wrong idal word list for the first ccw. Function ctcmpc_chx_txdone() invokes the function to prepare the idal word list without setting an appropriate length for the first ccw, which may lead to an incomplete idal word list.

The driver probe function queries the iomem resource and IRQ using standard platform_get functions.
