| | | | | | | | | | | | | Move loading of IDE_NSECTOR_REG from ide_cmd() to execute_drive_cmd() (load the IDE_NSECTOR_REG just after IDE_FEATURE_REG). This also allows us to drop 'nsect' argument from ide_cmd() and simplify execute_drive_cmd() code for REQ_TYPE_ATA_CMD case a bit.

This will allow filesystems to directly own and control all of their mount options if they so choose. This interface deals only with option identifiers and strings so it should generic enough for any LSM which may come in the future. Filesystems which pass text mount data around in the kernel (almost all of them) need not currently make use of this interface when dealing with SELinux since it will still parse those strings as it always has. I assume future LSM's would do the same. NFS is the primary FS which does not use text mount data and thus must make use of this interface. An LSM would need to implement these functions only if they had mount time options, such as selinux has context= or fscontext=. If the LSM has no mount time options they could simply not implement and let the dummy ops take care of things. An LSM other than SELinux would need to define new option numbers in security.h and any FS which decides to own there own security options would need to be patched to use this new interface for every possible LSM. This is because it was stated to me very clearly that LSM's should not attempt to understand FS mount data and the burdon to understand security should be in the FS which owns the options.

| * | [AVR32] extint: Set initial irq type to low levelHaavard Skinnemoen2008-01-251-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | David Brownell pointed out a mismatch in the avr32 extint code: > I noticed a small glitch that's not fixed by this patch: the > initial type is falling edge, but IRQ_TYPE_NONE is mapped to > IRQ_TYPE_LEVEL_LOW. Potentially surprising. Fix it by setting the initial type (and handler) to low level, matching the meaning of IRQ_TYPE_NONE. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * | [AVR32] extint: change set_irq_type() handlingDavid Brownell2008-01-251-11/+7
| | | | | | | | | | | | | | | | | | | | | | | | Update the AVR32 EIC code to use the new __set_irq_handler_unlocked() call, getting rid of one more instance of this widespread problem.

| * | [AVR32] NMI debuggingHaavard Skinnemoen2008-01-2510-10/+166
| | | | | | | | | | | | | | | | | | | | | | | | Change the NMI handler to use the die notifier chain to signal anyone who cares. Add a simple "nmi debugger" which hooks into this chain and that may dump registers, task state, etc. when it happens. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

| | | | | | | | | | | | | | | | | | | | | Turn off a few useless options, enable a few useful ones and enable quite a few new drivers. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * | [AVR32] Kconfig: Choose daughterboard instead of CPUHaavard Skinnemoen2008-01-252-24/+28
| | | | | | | | | | | | | | | | | | | | | | | | Remove the CPU selection menu and instead let it be selected by the board or daughterboard option. Add daughterboard selection for ATSTK1000 (this was previously determined based on CPU type.) Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * | [AVR32] Add support for ATSTK1003 and ATSTK1004Haavard Skinnemoen2008-01-258-20/+1975
| | | | | | | | | | | | | | | | | | | | | ATSTK1003 and ATSTK1004 are CPU daughterboards for ATSTK1000 featuring the AT32AP7001 and AT32AP7002 CPUs, respectively. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * | [AVR32] Clean up external DAC setup codeHaavard Skinnemoen2008-01-252-16/+17
| | | | | | | | | | | | | | | | | | | | | | | | Reduce the ridiculous amount of #ifdef clutter in atstk1002.c a bit by moving all the extdac stuff into its own function and providing an empty stub for the case when it isn't wanted. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
