The file looks as if it is non-modular, but it piggy-backs off CONFIG_SERIAL_8250 which is tristate. If set to "=m" we will get this after the init/module header cleanup: arch/mips/loongson/common/serial.c:76:1: error: data definition has no type or storage class [-Werror] arch/mips/loongson/common/serial.c:76:1: error: type defaults to 'int' in declaration of 'device_initcall' [-Werror=implicit-int] arch/mips/loongson/common/serial.c:76:1: error: parameter names (without types) in function declaration [-Werror] arch/mips/loongson/common/serial.c:58:19: error: 'serial_init' defined but not used [-Werror=unused-function] cc1: all warnings being treated as errors make[3]: *** [arch/mips/loongson/common/serial.o] Error 1 Make it clearly modular, and add a module_exit function, so that we avoid the above breakage.

Commit 854700115ecf ([MIPS] kgdb: add arch support for the kernel's kgdb core) added the 'kgdb_early_setup' flag to avoid calling trap_init() and init_IRQ() the second time, however the code that called these functions earlier, from kgdb_arch_init(), had been already removed by that time, so the flag never served any useful purpose. Remove the related code along with ugly #ifdef'ery at last. [ralf@linux-mips.org: Folded in Guenter Roeck's fix.] Signed-off-by:

Currently, code of Loongson-2/3 is under loongson directory and code of Loongson-1 is under loongson1 directory. Besides, there are Kconfig options such as MACH_LOONGSON and MACH_LOONGSON1. This naming style is very ugly and confusing. Since Loongson-2/3 are both 64-bit general- purpose CPU while Loongson-1 is 32-bit SoC, we rename both file names and Kconfig symbols from loongson/loongson1 to loongson64/loongson32.

Enable the 32-bit DMA zone for 64-bit Malta kernels so that devices with 32-bit coherent DMA masks aren't constrained to the low 16MB DMA zone, which can easily be exhausted when there is lots of static kernel data due to lock and RCU debugging. Signed-off-by:

Commit c5b36783 ("MIPS: Add support for XPA.") added generation of a shift by _PAGE_PRESENT_SHIFT in build_pte_present() and build_pte_writable(), however except for the XPA case this is always zero making it unnecessary. Make the shift conditional upon _PAGE_PRESENT_SHIFT being non-zero to save an instruction in those cases. Fixes: c5b36783 ("MIPS: Add support for XPA.") Signed-off-by:

Commit c5b36783 ("MIPS: Add support for XPA.") changed build_pte_present() and build_pte_writable() to assume a constant offset of _PAGE_READ and _PAGE_WRITE relative to _PAGE_PRESENT, however this is no longer true for some MIPS32R2 builds since commit be0c37c9 ("MIPS: Rearrange PTE bits into fixed positions.") which moved the _PAGE_READ PTE bit away from the _PAGE_PRESENT bit, with the _PAGE_WRITE bit falling into its place. Make use of the _PAGE_READ and _PAGE_WRITE definitions to calculate the correct mask to apply instead of hard coding 3 (for _PAGE_PRESENT | _PAGE_READ) or 5 (for _PAGE_PRESENT | _PAGE_WRITE).

KVM guest kernels for trap & emulate run in user mode, with a modified set of kernel memory segments. However the fixmap address is still in the normal KSeg3 region at 0xfffe0000 regardless, causing problems when cache alias handling makes use of them when handling copy on write. Therefore define FIXADDR_TOP as 0x7ffe0000 in the guest kernel mapped region when CONFIG_KVM_GUEST is defined. Signed-off-by:

The DDR controller need to be used by the IRQ controller to flush the write buffer of some devices before running the IRQ handler. It is also used by the PCI controller to setup the PCI memory windows. The current interface used to access the DDR controller doesn't provides any useful abstraction and simply rely on a shared global pointer. Replace this by a simple API to setup the PCI memory windows and use the write buffer flush independently of the SoC type. That remove the need for the shared global pointer, simplify the IRQ handler code. [ralf@linux-mips.org: Folded in Alban Bedel's follup fix.] Signed-off-by:
