* MIPS: oprofile: Only do performance counter handling for counter interruptsWu Zhangjin2009-12-171-1/+4
| | | | | | | | | In Loongson2f IP6 is shared by bonito and perfcounters so we need to avoid do_IRQ for perfcounter when the interrupt is from bonito. Signed-off-by: Wu Zhangjin <wuzhangjin@gmail.com> Cc: linux-mips@linux-mips.org Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* MIPS: Loongson: Cleanup the serial port supportWu Zhangjin2009-12-177-20/+60
| | | | | | | | | | | | | | | | | To share the same kernel image amon different machines we have added the machtype command line support. In the old serial port implementation the UART base address is hardcoded as a macro in machine.h which breaks with machtype, so change that to discover the address dynamically. Also move the initialization of the UART base address to uart_base.c to avoid remapping twice for early_printk.c and serial.c.

* MIPS: Collect FPU emulator statistics per-CPU.David Daney2009-12-173-50/+80
| | | | | | | | | | | | | | | | | | | On SMP systems, the collection of statistics can cause cache line bouncing in the lines associated with the counters. Also there are races incrementing the counters on multiple CPUs. To fix both problems, we collect the statistics in per-CPU variables, and add them up in the debugfs read operation. As a test I ran the LTP float_bessel test on a 12 CPU Octeon system. Without CONFIG_DEBUG_FS : 2602 seconds. With CONFIG_DEBUG_FS: 2640 seconds. With non-cpu-local atomic statistics: 14569 seconds.

* MIPS: Bonito64: Make Loongson independent from Bonito64 code.Wu Zhangjin2009-12-1715-55/+352
| | | | | | | | | | | | | | | | | | The built-in Loongson 2E/2F northbridge in is bonito64-compatible but not identical with it. To avoid influencing the original bonito64 support and make the loongson support more maintainable, it's better to separate the Bonito64 code from the Loongson code. This also prepares the kernel for the coming Loongson 2f machines family support.

* MIPS: Put PGD in C0_CONTEXT for 64-bit R2 processors.David Daney2009-12-175-14/+68
| | | | | | | | | | | | | | Processors that support the mips64r2 ISA can in four instructions convert a shifted PGD pointer stored in the upper bits of c0_context into a usable pointer. By doing this we save a memory load and associated potential cache miss in the TLB exception handlers. Since the upper bits of c0_context were holding the CPU number, we move this to the upper bits of c0_xcontext which doesn't have enough bits to hold the PGD pointer, but has plenty for the CPU number.

* NET: Add Ethernet driver for Octeon MGMT devices.David Daney2009-12-175-0/+1192
| | | | | | | | | | | | | | | | | | | | | The Octeon MGMT Ethernet ports are present in some members of the Octeon SOC family (cn52XX and cn56XX have them). The mdio bus connected to the MGMT PHYs is shared with the main octeon-ethernet driver, we force it to be loaded first by calling octeon_mdiobus_force_mod_depencency. The platform devices for the MGMT Ethernet ports are added in arch/mips/cavium-octeon/octeon-platform.c, and the register definitions for the ports live in arch/mips/include/asm/octeon/ along with their ilk. Although it currently is the only driver in drivers/net/octeon, the directory was created looking forward to the day that octeon-ethernet will move there from its current home in drivers/staging.

* NET: Add driver for Octeon MDIO buses.David Daney2009-12-174-0/+370
| | | | | | | | | | | | | | | | | The Octeon SOC has two types of Ethernet ports, each type with its own driver. However, the PHYs for all the ports are controlled by a common MDIO bus. Because the mdio driver is not associated with a particular driver, but is instead a system level resource, we create s stand-alone driver for it. As for the driver, we put the register definitions in arch/mips/include/asm/octeon where most of the other Octeon register definitions live. This is a platform driver with the platform device for "mdio-octeon" being registered in the platform startup code. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Acked-by: David S.

| * XFS: Free buffer pages array unconditionallyDave Chinner2009-12-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code in xfs_free_buf() only attempts to free the b_pages array if the buffer is a page cache backed or page allocated buffer. The extra log buffer that is used when the log wraps uses pages that are allocated to a different log buffer, but it still has a b_pages array allocated when those pages are associated to with the extra buffer in xfs_buf_associate_memory. Hence we need to always attempt to free the b_pages array when tearing down a buffer, not just on buffers that are explicitly marked as page bearing buffers. This fixes a leak detected by the kernel memory leak code. Signed-off-by: Dave Chinner <david@fromorbit.com> Signed-off-by: Alex Elder <aelder@sgi.com>

This patch adds a series of workarounds to allow the use of the second memory region (MEM2) as RAM by the kernel. Basically, a single range of memory from the beginning of MEM1 to the end of MEM2 is reported to the kernel, and a memory reservation is created for the hole between MEM1 and MEM2.
