2009-09-17MIPS: Loongson: PCI: use existing mips_io_port_baseWu Zhangjin
mips_io_port_base is initialized via set_io_port_base() in arch/mips/lemote/lm2e/setup.c, we can use it directly here. Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Loongson: pm: clean up the reboot supportWu Zhangjin
Several magic numbers have been replaced by relative macros, which will be more readable and understandable. Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Loongson: pm: Remove redundant source codeWu Zhangjin
The implmentation of loongson2e_power_off and loongson2e_halt is almostly the same, just preserve one of them. Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Loongson: Add new early_printk implmentationWu Zhangjin
This patch is based on the implementation in the lm2e-fixes branch of Philippe's git://git.linux-cisco.org/linux-mips.git and the malta-specific early_printk implementation. Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Loongson: Remove out-of-date board-specific kgdb source codeWu Zhangjin
Since the re-implementation of kgdb by commit 8854700115ecf8aa6f087aa915b7b6cf18090d39 the platform-specific version has become superfluous, remove it. Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Loongson: Remove existing early_printk implementationWu Zhangjin
Removes the existing implementation of early_printk for fulong. The old implementation was based on the outdated board-specific dbg_io.c. Since commit 8d60a903d986ffa26c41f0092320a3b9da20bfaf dbg_io.c is not longer needed; it will be removed by the next patch, and a new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.

Error handling code following a kzalloc should free the allocated data. Error handling code following an ioremap should iounmap the allocated data.

2009-09-17MIPS: Alchemy: add gpio_request/gpio_free stubs for CONFIG_GPIOLIB=nManuel Lauss

2009-09-17MIPS: Lasat: Fix compilationAlexey Dobriyan
Header needed for current_cpu_data which expands to smp_processor_id(). However, linux/smp.h can't be included into asm/cpu-info.h due to horrible circular dependencies, so plug it here. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Octeon: Check all CCAs in cvmx_write_csr.David Daney
The current code only checks CCA of 0 when deciding if a dummy read is needed. Since the kernel can (and does) use other CCAs we need to mask out the CCA bits from the address. Since the address constant now fits in 16 bits, there is an added benefit that smaller code is generated.

2009-09-17MIPS: Octeon: False positive timeoutRoel Kluin
If we reach the test just below the loop with a `timeout' value of 0, this does not mean that the timeout caused the loop to end, but rather the `smi_rd.s.pending', in the last iteration. If timeout caused the loop to end, then `timeout' is -1, not 0. Since this can occur only in the last iteration, it is not very likely to be a problem. By changing the post- to prefix decrement we ensure that a timeout of 0 does mean it timed out.

2009-09-16Blackfin: update ftrace for latest toolchainYi Li
The mcount support that was finally added to the Blackfin gcc port isn't exactly the same as what ftrace was developed against. Now that the final gcc version is in place, update the ftrace code to match. While updating this, fix the swapped arguments to the tracer (signature is (ip, parent_ip) while we were passing (parent_ip, ip)).

2009-09-16Blackfin: fix elf_fpregset_t definitionMike Frysinger
The elf_fpregset_t type relied on an empty struct in the asm/user.h, but the transition to asm-generic/user.h dropped that empty struct. Rather than restore this useless struct, define the only user (elf_fpregset_t) as an empty struct itself. This fixes building when ELF dump support is enabled.

2009-09-16Blackfin: unify cache init functionsMike Frysinger

2009-09-16Blackfin: use raw_smp_processor_id() in exception codeYi Li
When preempt debugging is enabled, smp_processor_id() may utilize the "current" structure. This may not be safe to access under all exceptions due to it being in dynamically allocated memory.

2009-09-16Blackfin: optimize fixed code handling for the most common caseMike Frysinger
The majority of the time we are returning to user space, it is not in the fixed atomic code region.
