2013-03-07tg3: Download 57766 EEE service patch firmwareNithin Sujir2-16/+128

2013-03-07tg3: Enhance firmware download code to support fragmented firmwareNithin Sujir1-6/+42
This lays the ground work to download the 57766 fragmented firmware. We loop until we've written data equal to tp->fw->size minus headers.

2013-03-07tg3: Cleanup firmware parsing codeNithin Sujir2-36/+34
The current firmware header parsing is complicated due to interpreting it as a u32 array and accessing header members via array offsets. Add tg3_firmware_hdr structure to access the firmware fields instead of hardcoding offsets. The same header format will be used for individual firmware fragments in the 57766. The fw_hdr and tg3 structures have all the information required for loading the fw. Remove the redundant fw_info structure and pass fw_hdr instead.

2013-03-07tg3: Refactor the 2nd type of cpu pauseNithin Sujir1-26/+27
For completeness and consistency, add common function tg3_pause_cpu_and_set_pc(). This is only for existing fw and not used for the 57766.

2013-03-07tg3: Refactor cpu pause/resume codeNithin Sujir1-25/+58
The 57766 rxcpu needs to be paused/resumed when we download the firmware just like we do for existing firmware. Refactor the pause/resume code to be reusable. This patch also renames the "offset" argument of tg3_halt_cpu to "cpu_base" since that's what it really is.

2013-03-07tg3: Add new FW_TSO flagMatt Carlson2-8/+8
tg3 used the fw_needed member loosely as a synonym for firmware TSO. Now that the 57766 needs firmware download support, fw_needed can no longer be used like this. This patch creates a new FW_TSO flag and changes the code to use it. Also rearrange all the TSO flags together in the enum.

2013-03-07qlcnic: Use generic fdb handler when driver options are not enabled.Vlad Yasevich1-15/+6
Allow qlcnic to use the generic fdb handler when the driver options are not enabled. Untill the driver is fully fixed, this allows the use of the FDB interface with qlogic driver, but simply puts the driver into promisc mode since the driver currently does not support IFF_UNICAST_FLT.

2013-03-05hw_random: make buffer usable in scatterlist.Rusty Russell1-3/+16
virtio_rng feeds the randomness buffer handed by the core directly into the scatterlist, since commit bb347d98079a547e80bd4722dee1de61e4dca0e8. However, if CONFIG_HW_RANDOM=m, the static buffer isn't a linear address (at least on most archs). We could fix this in virtio_rng, but it's actually far easier to just do it in the core as virtio_rng would have to allocate a buffer every time (it doesn't know how much the core will want to read).

This is a resubmission. Added kfree() in ax88179_get_eeprom to prevent memory leakage. Modified "__le16 rxctl" to "u16 rxctl" in "struct ax88179_data" and removed pointless casts. Removed asix_init and asix_exit functions and added "module_usb_driver(ax88179_178a_driver)". Fixed endianness issue on big endian systems and verified this driver on iBook G4. Removed steps that change net->features in ax88179_set_features function. Added "const" to ethtool_ops structure and fixed the coding style of AX88179_BULKIN_SIZE array. Fixed the issue that the default MTU is not 1500. Added ax88179_change_mtu function and enabled the hardware jumbo frame function to support an MTU higher than 1500. Fixed indentation and empty line coding style errors. The _nopm version usb functions were added to access register in suspend and resume functions. Serveral variables allocted dynamically were removed and replaced by stack variables. ax88179_get_eeprom were modified from asix_get_eeprom in asix_common. This patch adds a driver for ASIX's AX88179 family of USB 3.0/2.0 to gigabit ethernet adapters. It's based on the AX88xxx driver but the usb commands used to access registers for AX88179 are completely different.

Need to consider sequence is: numaq, srat, amd, dummy. and make fall back path working. 2. simply split acpi_numa_init to early_parse_srat. a. that early_parse_srat is NOT called for ia64, so you break ia64. b. for (i = 0; i < MAX_LOCAL_APIC; i++) set_apicid_to_node(i, NUMA_NO_NODE) still left in numa_init. So it will just clear result from early_parse_srat. it should be moved before that.... c. it breaks ACPI_TABLE_OVERIDE...as the acpi table scan is moved early before override from INITRD is settled. 3. that patch TITLE is total misleading, there is NO x86 in the title, but it changes critical x86 code. It caused x86 guys did not pay attention to find the problem early. Those patches really should be routed via tip/x86/mm. 4. after that commit, following range can not use movable ram: a. real_mode code.... well..funny, legacy Node0 [0,1M) could be hot-removed? b. initrd... it will be freed after booting, so it could be on movable... c. crashkernel for kdump...: looks like we can not put kdump kernel above 4G anymore. d. init_mem_mapping: can not put page table high anymore. e. initmem_init: vmemmap can not be high local node anymore. That is not good. If node is hotplugable, the mem related range like page table and vmemmap could be on the that node without problem and should be on that node. We have workaround patch that could fix some problems, but some can not be fixed. So just remove that offending commit and related ones including: f7210e6c4ac7 ("mm/memblock.c: use CONFIG_HAVE_MEMBLOCK_NODE_MAP to protect movablecore_map in memblock_overlaps_region().") 01a178a94e8e ("acpi, memory-hotplug: support getting hotplug info from SRAT") 27168d38fa20 ("acpi, memory-hotplug: extend movablemem_map ranges to the end of node") e8d195525809 ("acpi, memory-hotplug: parse SRAT before memblock is ready") fb06bc8e5f42 ("page_alloc: bootmem limit with movablecore_map") 42f47e27e761 ("page_alloc: make movablemem_map have higher priority") 6981ec31146c ("page_alloc: introduce zone_movable_limit[] to keep movable limit for nodes") 34b71f1e04fc ("page_alloc: add movable_memmap kernel parameter") 4d59a75125d5 ("x86: get pg_data_t's memory from other node") Later we should have patches that will make sure kernel put page table and vmemmap on local node ram instead of push them down to node0. Also need to find way to put other kernel used ram to local node ram.

2013-03-02kgdb/kgdbts: support ppc64Tiejun Chen1-0/+2
We can't look up the address of the entry point of the function simply via that function symbol for all architectures. For PPC64 ABI, actually there is a function descriptors structure. A function descriptor is a three doubleword data structure that contains the following values: * The first doubleword contains the address of the entry point of the function. * The second doubleword contains the TOC base address for the function. * The third doubleword contains the environment pointer for languages such as Pascal and PL/1. So we should call a wapperred dereference_function_descriptor() to get the address of the entry point of the function. Note this is also safe for other architecture after refer to "include/asm-generic/sections.h" since: dereference_function_descriptor(p) always is (p) if without arched definition.

2013-03-02gpio/gpio-ich: fix ichx_gpio_check_available() return what callers expectMika Westerberg1-2/+2
ichx_gpio_check_available() returns either 0 or -ENXIO depending on whether the given GPIO is available or not. However, callers of this function treat the return value as boolean: ... if (!ichx_gpio_check_available(gpio, nr)) return -ENXIO; which erroneusly fails when the GPIO is available and not vice versa. Fix this by making the function return boolean as expected by the callers. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
