The userspace runtime linker uses the elf_platform to find the libraries optimized for the current CPU archecture variant. First we need to allow it to be set to something other than NULL. Follow-on patches will set some values for specific CPUs. GLIBC already does the right thing. The kernel just needs to supply good data. Signed-off-by:

Although the hardware supports a 4/8bit SD interface and the driver unconditionally advertises all hardware caps to the MMC core, not all datalines may actually be wired up. This patch introduces another field to au1xmmc platform data allowing platforms to disable certain advanced host controller features. Signed-off-by:

AR7 has a larger physical offset than other MIPS based systems and therefore needs to setup its handlers beyond the usual KSEG0 range. When running the kernel in mapped mode this modification is also required. Remove function comment which is now incorrect. Signed-off-by:

I believe these changes are needed on Alchemy SoCs in order to use iomem above 4G with the usual platform_device machinery: - Set CONFIG_ARCH_PHYS_ADDR_T_64BIT to make resource_size_t 64-bit. - Increase IOMEM_RESOURCE_END so that platforms can register resources.

In the old source code, I have let halt and poweroff do the same action, but in reality, they have different meanings. As the manpage of shutdown shows: -r Reboot after shutdown. -H Halt action is to halt or drop into boot monitor on systems that support it. -P Halt action is to turn off the power. and in the real world, some machines(e.g. NAS) did not provide a power button and the shutdown works as reset, so, we need to provide a mechanism to let the users turn off the power safely without breaking the system, such a mechanism is "halt", which only put the system into a dead loop or a power-save mode and print some information to the screen to tell the users to turn off the power safely. $ shutdown -hH now /* loongson_halt, not turn off the power */ $ shutdown -hP now /* loongson_poweroff, work as poweroff */ Signed-off-by:

For processors that have more than 64 TLBs, we need to decode both config1 and config4 to determine the total number TLBs. Signed-off-by:
-
David Daney authored
The function probe_tlb() only does anything for processors that are not PRID_COMP_LEGACY. This is precisely the set of processors for which decode_configs() is called to do identical tlbsize probing calculations. Therefore probe_tlb() is completely redundant and may be removed. Signed-off-by:

MIPS currently lacks the readl_be and writel_be accessors which are required by BCM63xx for OHCI and EHCI support. Let's define them globally for MIPS. This also fixes the compilation of the bcm63xx defconfig against USB. Signed-off-by:

Changes: o Serial port related configuration Disable EARLY_PRINTK, CONFIG_SYS_SUPPORTS_ZBOOT_UART16550 Enable the serial port support as module. o PM related support Enable CPUFreq as module, use the external timer(MFGPT) instead of r4k timer. Enable Suspend support Enable Run Time PM support o Enable SM7XX Video Driver Disable the buggy 2d acceleration o Enable CONFIG_OPROFILE as module o Use GZIP instead of LZMA, which need less decompression time o Enable more USB devices support o Enable initrd support(needed by gNewsense) o Enable more crypto support Signed-off-by: -

The compressed kernel support on loongson family machines is stable now, so, remove the debug information via using SYS_SUPPORTS_ZBOOT instead of SYS_SUPPORTS_ZBOOT_UART16550. This may reduce the image size and speedup the booting. Signed-off-by:

Lemote have used the PMON_VER strings to indicate the loongson-2f machine series: PMON_VER=LM8089 Lemote 8.9'' netbook LM8101 Lemote 10.1'' netbook (The above two netbooks have the same kernel support) LM6XXX Lemote FuLoong(2F) box series LM9XXX Lemote LynLoong PC series Before the machtype is supported by the PMON, we can get the machine type from the PMON_VER for these machines, this will help the users a lot.

Octeon ethernet hardware can handle NETIF_F_SG, so we enable it. A gather list of up to six fragments will fit in the SKB's CB structure, so no extra memory is required. If a SKB has more than six fragments, we must linearize it. Signed-off-by:

Convert the driver to be a reasonably well behaved NAPI citizen. There is one NAPI instance per CPU shared between all input ports. As receive backlog increases, NAPI is scheduled on additional CPUs. Receive buffer refill code factored out so it can also be called from the periodic timer. This is needed to recover from temporary buffer starvation conditions. Signed-off-by:

After aligning the blocks returned by kmalloc, we need to save the original pointer so they can be correctly freed. There are no guarantees about the alignment of SKB data, so we need to handle worst case alignment. Since right shifts over subtraction have no distributive property, we need to fix the back pointer calculation. Signed-off-by:

If an interrupt handler disables interrupts, the EOI function will just reenable them. This will put us in an endless loop when the upcoming Ethernet driver patches are applied. Only reenable the interrupt on EOI if it is not IRQ_DISABLED. This requires that the EOI function be separate from the ENABLE function. We also rename the ACK functions to correspond with their function. Signed-off-by:
