2007-07-18UBI: use vmalloc for large buffersArtem Bityutskiy
UBI allocates temporary buffers of PEB size, which may be 256KiB. Use vmalloc instead of kmalloc for such big temporary buffers. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2007-07-18UBI: fix error path in create_vtbl()Artem Bityutskiy
There were several bugs in volume table creation error path. Thanks to Satyam Sharma <satyam.sharma@gmail.com> and Florin Malita <fmalita@gmail.com> for finding and analysing them: http://lkml.org/lkml/2007/5/3/274 This patch makes ubi_scan_add_to_list() static and renames it to add_to_list(), just because it is not needed outside scan.c anymore.

2007-07-17Revert drivers/ide/ide.c scsi_cmd_ioctl() usage changesLinus Torvalds
The old IDE driver is not ready to take generic SCSI commands, even if it uses them for some specific issues (ie the tray open/close ioctls for IDE CD-ROM's). Pointed out by Bartlomiej. I'm sure we'll have it fixed properly soon enough, but for now we should not allow it to cause problems.

2007-07-17[ISDN] HiSax netjet_s: code movement, prep for hotplugJeff Garzik
1) Remove CONFIG_PCI ifdefs. PCI is required in Kconfig. 2) Break up setup_netjet_s() into three separate internal functions. This helps facilitate upcoming use of PCI hotplug API, and in addition makes the code much easier to follow. No code is changed, just moved around. I even kept the out-of-favor "return(0)" style used in the current source code. Signed-off-by: Jeff Garzik <jeff@garzik.org>

This episode illustrates how an overused warning can train people to ignore that warning, which winds up hiding bugs.

2007-07-17md: change bitmap_unplug and others to void functionsNeilBrown
bitmap_unplug only ever returns 0, so it may as well be void. Two callers try to print a message if it returns non-zero, but that message is already printed by bitmap_file_kick. write_page returns an error which is not consistently checked. It always causes BITMAP_WRITE_ERROR to be set on an error, and that can more conveniently be checked. When the return of write_page is checked, an error causes bitmap_file_kick to be called - so move that call into write_page - and protect against recursive calls into bitmap_file_kick. bitmap_update_sb returns an error that is never checked. So make these 'void' and be consistent about checking the bit.

2007-07-17md: check that internal bitmap does not overlap other dataNeilBrown
We current completely trust user-space to set up metadata describing an consistant array. In particlar, that the metadata, data, and bitmap do not overlap.

2007-07-17OMAP: add TI TWL92330/Menelaus Power Management chip driverTony Lindgren
Add Texas Instruments TWL92330/Menelaus Power Management chip driver. This includes voltage regulators, Dual slot memory card tranceivers and real-time clock(RTC). The support for RTC is integrated with this driver only; it is not separate module. Passes 'rtctest' on OMAP H4 EVM, other than lack of "periodic" (1/N second) IRQs. System wakeup alarms (from suspend-to-RAM) work too. The battery keeps the RTC active over power off, so once you set clock (rdate/ntpdate/etc, then "hwclock -w") then RTC_HCTOSYS at boot time will behave as expected.
