* KVM/MIPS32: KVM Guest kernel support.Sanjay Lal2013-05-087-3/+52
| | | | | | | | | | | | | Both Guest kernel and Guest Userspace execute in UM. The memory map is as follows: Guest User address space: 0x00000000 -> 0x40000000 Guest Kernel Unmapped: 0x40000000 -> 0x60000000 Guest Kernel Mapped: 0x60000000 -> 0x80000000 - Guest Usermode virtual memory is limited to 1GB.

| | | | | | | | | | | - Implements the arch specific APIs for KVM, some are stubs for MIPS - kvm_mips_handle_exit(): Main 'C' distpatch routine for handling exceptions while in "Guest" mode. - Also implements in-kernel timer interrupt support for the guest.

* KVM/MIPS32: Entry point for trampolining to the guest and trap handlers.Sanjay Lal2013-05-081-0/+650
| | | | | | | | | | | | | | - __kvm_mips_vcpu_run: main entry point to enter guest, we save kernel context, load up guest context from and ERET to guest context. - mips32_exception: L1 exception handler(s), save k0/k1 and jump to main handlers. - mips32_GuestException: Generic exception handlers for exceptions/interrupts while in guest context.

* MIPS: IP27: Remove pfn_t.Ralf Baechle2013-05-084-11/+10
| | | | | | | | | In the Linux kernel traditionally pfns are represented by an unsigned long. However a few bits of the SGI IP27 platform code that were ported from IRIX are using pfn_t for historic reasons. This is conflicting with KVM's use of pfn_t.

| * watchdog: ath79_wdt: get register base from platform device's resourcesGabor Juhos2013-03-011-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ath79_wdt driver uses a fixed memory address currently. Although this is working with each currently supported SoCs, but this may change in the future. Additionally, the driver includes platform specific header files in order to be able to get the memory base of the watchdog device. The patch adds a memory resource to the platform device, and converts the driver to get the base address of the watchdog device from that.

The biggy in there is a whitespace cleanup. After I was sent another set of whitespace cleanup patches I decided it was the time to clean the whitespace "issues" for once and and that touches many files below arch/mips/.

Use the parent resource if it is available in the request_resource call to avoid the isssue.
