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.

The function prom_init_cmdline() doesn't do anything, and nobody calls the prom_getcmdline() function.

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.

由 David Daney 提交于
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.

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: NDavid Daney <ddaney@caviumnetworks.com> Acked-by: NDavid S.

This patch helps to generate smaller kernel images for linux-MIPS, Here is the effect when using lzma: $ ls -sh vmlinux 7.1M vmlinux $ ls -sh vmlinuz 1.5M vmlinuz Have tested the 32bit kernel on Qemu/Malta and 64bit kernel on FuLoong Mini PC. both of them work well. and also, tested by Alexander Clouter on an AR7 based Linksys WAG54Gv2, and by Manuel Lauss on an Alchemy board. This -v2 version incorporate the feedback from Ralf, and add the following changes: 1. add .ecoff, .bin, .erec format support 2. only enable it and the debug source code for the machines we tested 3. a dozen of fixups and cleanups and if you want to enable it for your board, please try to select SYS_SUPPORTS_ZBOOT for it, and if the board have an 16550 compatible uart, you can select SYS_SUPPORTS_ZBOOT_UART16550 directly. and then sending the relative patches to Ralf.

Commit 3d1e4631 ("get rid of init_file()") removed the export of alloc_file() -- possibly inadvertently, since that commit mainly consisted of deleting the lines between the end of alloc_file() and the start of the code in init_file(). There is in fact one modular use of alloc_file() in the tree, in drivers/infiniband/core/uverbs_main.c, so re-add the export to fix: ERROR: "alloc_file" [drivers/infiniband/core/ib_uverbs.ko] undefined! when CONFIG_INFINIBAND_USER_ACCESS=m.

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: NDave Chinner <david@fromorbit.com> Signed-off-by: NAlex Elder <aelder@sgi.com>

Change all async metadata buffers to use [READ|WRITE]_META I/O types so that the I/O doesn't get issued immediately. This allows merging of adjacent metadata requests but still prioritises them over bulk data. This shows a 10-15% improvement in sequential create speed of small files. Don't include the log buffers in this classification - leave them as sync types so they are issued immediately.
