* sparseirq: Allow early irq_desc allocationPaul Mundt2009-05-231-4/+14
| | | | | | | | | | | | | | | | | | | Presently non-legacy IRQs have their irq_desc allocated with kzalloc_node(). This assumes that all callers of irq_to_desc_node_alloc() will be sufficiently late in the boot process that kmalloc is available. While porting sparseirq support to sh this blew up immediately, as at the time that we register the CPU's interrupt vector map only bootmem is available. Check slab_is_available() to work out which path to use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ed found that on 32-bit, boot_cpu_physical_apicid is not read right, when the mptable is broken.

We trust the hardware register more than we trust a BIOS data structure (the mptable). We can also avoid the double set_fixmap() when acpi_lapic is used, and also need to move cpu_has_apic earlier and call apic_disable(). Also when need to update the apic id, we'd better read and set the apic version as well - so that quirks are applied precisely. v2: make path 3 with 64bit, use -1 as apic id, so could read it later. v3: fix whitespace problem pointed out by Ed Swierk v5: fix boot crash [ Impact: get correct apic id for bsp other than acpi path ] Reported-by: Ed Swierk <eswierk@aristanetworks.com> Signed-off-by: Yinghai Lu <yinghai@kernel.org> Acked-by: Cyrill Gorcunov <gorcunov@openvz.org> LKML-Reference: <49FC85A9.2070702@kernel.org> [ v4: sanity-check in the ACPI case too ] Signed-off-by: Ingo Molnar <mingo@elte.hu>

If the whole device is successfully erased, erase_chip() will return 0, and the code will fall through to the "else" clause, and do sector-by-sector erase in addition to the whole-chip erase. This patch corrects that. Also, the MAX_READY_WAIT_COUNT is insufficient for an m25p16 connected to a 400 MHz powerpc. Increasing it allows me to successfully program the device on my board.

Although NTLMSSP encapsulated in SPNEGO is not enabled yet, "raw" ntlmssp is common and useful in some cases since it offers more complete security negotiation, and is the default way of negotiating security for many Windows systems. SPNEGO encapsulated NTLMSSP will be able to reuse the same code. Signed-off-by: Steve French <sfrench@us.ibm.com>
