There is a bunch of platform device registration in arch/mips/cavium-octeon/setup.c. We move it to its own file in preparation for adding more platform devices. Signed-off-by: NDavid Daney <ddaney@caviumnetworks.com> Signed-off-by: NRalf Baechle <ralf@linux-mips.org>

The code after the vmalloc_fault: label in do_page_fault() modifies user page tables, this is not correct for 64-bit kernels. For 64-bit kernels we should go straight to the no_context handler skipping vmalloc_fault. Signed-off-by: NDavid Daney <ddaney@caviumnetworks.com> Signed-off-by: NRalf Baechle <ralf@linux-mips.org>

By combining swapper_pg_dir and module_pg_dir, several if conditions can be eliminated from the tlb exception handler. The reason they can be combined is that, the effective virtual address of vmalloc returned is at the bottom, and of module_alloc returned is at the top. It also fixes the bug in vmalloc(), which happens when its return address is not covered by the first pgd.

Eliminate the 'allow_au1k_wait' variable. MIPS kernel installs the Alchemy-specific wait code before timer initialization; if the C0 timer must be used for timekeeping the wait function is set to NULL which means no wait implementation is available. As a sideeffect, the 'wait instruction available' output in /proc/cpuinfo now correctly indicates whether 'wait' is usable. Run-tested on DB1200.

On some CPUs, it is more efficient to disable and enable interrupts in the kernel rather than use ll/sc for atomic operations. But if we were to set cpu_has_llsc to false, we would break the userspace futex interface (in asm/futex.h). We separate the two concepts, with a new predicate kernel_uses_llsc, that lets us disable the kernel's use of ll/sc while still allowing the futex code to use it. Also there were a couple of cases in bitops.h where we were using ll/sc unconditionally even if cpu_has_llsc were false.

CONFIG_CPU_HAS_LLSC duplicated the function of cpu_has_llsc for no good reason and and the results if the one was enabled and the other disabled was very unobvious. Remove it now that there are no more remaining users. Signed-off-by: NRalf Baechle <ralf@linux-mips.org>

Now that PAGE_SIZE is available to assembly directly, there is no need to separately expose it as _PAGE_SIZE through asm-offsets. In addition, remove _PAGE_SHIFT from asm-offsets, since it was never needed, and is not used anywhere.

This patch makes the board code register the ar7_wdt driver as a platform device.

Because only gcc >=4.4 have loongson-specific support, we need to choose the suitable -march argument for gcc <= 4.3 and gcc >= 4.4, and here, we use -march=loongson2e for loongson2e. Thanks goes to Arnaud Patard <apatard@mandriva.com> for suggestion of using cc-options(Documentation/kbuild/makefiles.txt). and thanks Zhang Le for introducing the new CPU_LOONGSON2E kernel option. NOTE: -mtune option is not need if -march and -mtune use the same value.

The difference between some loongson-based machines is very small, so, if there is no necessary to add new kernel config options to cope with this difference, it will be better to share the same kernel image file between them, benefit from this, the linux distribution developers only have a need to compile the kernel one time. This machtype kernel command line argument will be used later to share the same kernel image file between two different machines(menglong & yeeloong) made by lemote. Thanks very much to Zhang Le for cleaning up the machtype implementation. Signed-off-by: NWu Zhangjin <wuzhangjin@gmail.com> Signed-off-by: NRalf Baechle <ralf@linux-mips.org>

To share common loongson source code between all of the loongson-based machines. there is a need to split it out of the fuloong-2e/ directory. at the same time, other according tuning is needed. the machine-specific parts are defined as macros in relative header file, pci.h, mem.h, machine.h.

To make source code of loongson sharable to the machines(such as gdium) made by the other companies, we rename arch/mips/lemote to arch/mips/loongson, asm/mach-lemote to asm/mach-loongson, and rename lm2e to the name of the machine: fuloong-2e. accordingly, FULONG are renamed to FULOONG2E to make it distinguishable to the future FULOONG2F. and also, some other relative tuning is needed.

This kernel support is needed by the user-space tool:oprofile to profile linux kernel or applications via loongson2 performance counters. you can enable this driver via CONFIG_OPROFILE = y or m. On Loongson2 there are two performance counters, each one can count 16 events respectively. when anyone of the performance counter overflows, an interrupt will be generated and is routed to the IRQ MIPS_CPU_IRQ_BASE + 6.

With the help of script/checkpatch.pl, i have cleaned up the coding style. 1. remove un-needed header files and tune some comments. 2. remove some un-needed { } add a new header file loongson.h: 3. move some common header files to loongson.h 4. move some common extern declartions to loongson.h and this new header file is needed for future loongson2f support.

This patch split the old initilization and setup implementation to several file, one file one logic function. the other main changes include: 1. as the script/checkpatch.pl suggests, use strict_strtol instead of simple_strtol in arch/mips/lemote/lm2e/cmdline.c 2. use the existed macros in asm/mips-boards/bonito64.h as the arguments of set_io_port_base() and remove the un-needed ones in asm/mach-lemote/pci.h Signed-off-by: NWu Zhangjin <wuzj@lemote.com> Signed-off-by: NRalf Baechle <ralf@linux-mips.org>

Removes the existing implementation of early_printk for fulong. The old implementation was based on the outdated board-specific dbg_io.c. Since commit 8d60a903 dbg_io.c is not longer needed; it will be removed by the next patch, and a new implementation of early_printk will be added later.
