* uml: reconst a parameterJeff Dike2008-02-05
| | | | | | | | | | | | | The previous const-ing patch consted a string which shouldn't have been, and I didn't notice the gcc warning. ubd_setup can't take a const char * because its address is assigned to something which expects a char *arg. Many setups modify the string they are given, they can't be const.

* uml: tidy kern_util.hJeff Dike2008-02-05
| | | | | | | | | | | | | | | | | | | | | Tidy kern_util.h. It turns out that most of the function declarations aren't used, so they can go away. os.h no longer includes kern_util.h, so files which got it through os.h now need to include it directly. A number of other files never needed it, so these includes are deleted. The structure which was used to pass signal handlers from the kernel side to the userspace side is gone. Instead, the handlers are declared here, and used directly from libc code. This allows arch/um/os-Linux/trap.c to be deleted, with its remnants being moved to arch/um/os-Linux/skas/trap.c. arch/um/os-Linux/tty.c had its inclusions changed, and it needed some style attention, so it got tidied.

* uml: borrow const.h techniquesJeff Dike2008-02-05
| | | | | | | | | | | | | | | | Suggested by Geert Uytterhoeven - use const.h to get constants that are usable in both C and assembly. I can't include it directly since this code can't include kernel headers. const.h is also for numeric constants that can be typed by tacking a "UL" or similar on the end. The constants here have to be typed by casting them. So, the relevant parts of const.h are copied here and modified in order to allow the constants to be uncasted in assembly and casted in C.

* uml: further bugs.c tidyingJeff Dike2008-02-05
| | | | | | | | | | | | | | | | | | | | | | bugs.c, for both i386 and x86_64, can undergo further cleaning - The i386 arch_check_bugs only does one thing, so we might as well inline the cmov checking. The i386 includes can be trimmed down a bit. arch_init_thread wasn't used, so it is deleted. The panics in arch_handle_signal are turned into printks because the process is about to get segfaulted anyway, so something is dying no matter what happens here. Also, the return value was always the same, so it contained no information, so it can be void instead. The name is changed to arch_examine_signal because it doesn't handle anything. The caller of arch_handle_signal, relay_signal, does things in a different order. The kernel-mode signal check is now first, which puts everything else together, making things a bit clearer conceptually.

* gpiolib: avr32 at32ap platform supportDavid Brownell2008-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Teach AVR32 to use the "GPIO Library" when exposing its GPIOs, so that signals on external chips (like GPIO expanders) can easily be used. This mostly reorganizes some existing logic, with two minor changes in behavior: - The PSR registers are used instead of the previous "gpio_mask" values, matching AT91 behavior and removing some duplication between that role and that of "pinmux_mask". - NR_IRQs grew to acommodate a bank of external GPIOs. Eventually this number should probably become a board-specific config option. There's a debugfs dump of status for the built-in GPIOs, showing which pins have deglitching, pullups, or open drain drive enabled, as well as the ID string used when requesting each IRQ.

| | | | | | | | | | | | | | | | | | | | | | | | Add an empty drivers/gpio directory for gpiolib infrastructure and GPIO expanders. It will be populated by later patches. This won't be the only place to hold such gpio_chip code. Many external chips add a few GPIOs as secondary functionality (such as MFD drivers) and platform code frequently needs to closely integrate GPIO and IRQ support. This is placed *early* in the build/link sequence since it's common for other drivers to depend on GPIOs to do their work, so they must be initialized early in the device_initcall() sequence.

| | | | | | | | | | | | | | | | | This patch converts gart IOMMU to use the IOMMU helper functions. The IOMMU doesn't allocate a memory area spanning LLD's segment boundary anymore.

* iommu sg: powerpc: remove DMA 4GB boundary protectionFUJITA Tomonori2008-02-05
| | | | | | | | | | | | | | | | | | | Previously, during initialization of the IOMMU tables, the last entry at each 4GB boundary is marked as used since there are many adapters which cannot handle DMAing across any 4GB boundary. The IOMMU doesn't allocate a memory area spanning LLD's segment boundary anymore. The segment boundary of devices are set to 4GB by default. So we can remove 4GB boundary protection now.

| | | | | | | | | | | | | | | | | This patch converts PPC's IOMMU to use the IOMMU helper functions. The IOMMU doesn't allocate a memory area spanning LLD's segment boundary anymore. iseries_hv_alloc and iseries_hv_map don't have proper device struct. 4GB boundary is used for them.
