* sh: Add -mno-fdpic to default flags.Paul Mundt2008-06-09
| | | | | | | | | Presently the --fdpic specifier and the --isa matching clash when building with FDPIC toolchains. As we have no interest in building the kernel with --fdpic in the first place, always try to add in -mno-fdpic to the default flags. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: fix USBF resource for sh7722Magnus Damm2008-05-22
| | | | | | | | | | | | The USBF function on sh7722 is currently not working with the m66592_udc driver. The driver is using platform_get_resource_byname() so my commit a0d29798e568116aa6c32aef7bab2d9e620c88ad broke sh7722 support. The long term fix is to replace platform_get_resource_byname() in the driver with platform_get_resource(), but this helps until that happens.

* | sh: Fix up restorer in debug_trap exception return path.Paul Mundt2008-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a few different types of debug trap exceptions, though now that they are all going through a special jump table, the restorer needs to be unified as well. Presently this is falling through the ret_from_fork path, which more or less does the right thing on SH-3/4 whilst being completely unsuitable on MMU-less targets. Ultimately what we want here is a branch through the platform's restore_all directly, without worrying about the retval being clobbered. We can accomplish that through a branch to __restore_all directly, so switch it so we come back from the jump table and branch to the restorer. This fixes up a recursion in the nommu WARN_ON() path, as well as some other userspace nastiness where said recursion caused serious stack corruption. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | sh: Make is_valid_bugaddr() more intelligent on nommu.Paul Mundt2008-05-19
| | | | | | | | | | | | | | | | | | Currently is_valid_bugaddr() is true for anything >= PAGE_OFFSET, which happens to be 0 on nommu configurations. Make this a bit smarter by just reading in the opcode and comparing it against the trap type that we already know. Follows the logic from avr32. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* | sh: disable initrd defaults in .empty_zero_page.Paul Mundt2008-05-16
| | | | | | | | | | | | | | | | | | | | When using initramfs on systems that don't explicitly clear LOADER_TYPE, unpack_to_rootfs() tramples tramples the range with the defaults taken out of .empty_zero_page. This causes kernels with valid initramfs images to bail out with crc or gzip magic mismatch errors after the second unpack takes place on certain platform configurations.
