2007-06-01ALPHA: correct low-level I/O routines for sable-lynxJay Estabrook
This code corrects the behavior of the t2_readX/t2_writeX routines, and t2_ioreadNN/t2_iowriteNN routines. The value T2_DENSE_MEM is now subtracted from the "xaddr" argument in each of the readX/writeX routines, since those routines may be called directly, rather than always through the ioreadNN/iowriteNN routines. Examples of the direct calls, via the __raw_readX/writeX macros, are the memcpy_fromio/toio, _memset_c_io, and scr_memcpyw routines.

2007-06-01ALPHA: support graphics on non-zero PCI domainsJay Estabrook
This code replaces earlier and incomplete handling of graphics on non-zero PCI domains (aka hoses or peer PCI buses). An option (CONFIG_VGA_HOSE) is set TRUE if configuring a GENERIC kernel, or a kernel for MARVEL, TITAN, or TSUNAMI machines, as these are the machines whose SRM consoles are capable of configuring and handling graphics options on non-zero hoses. All other machines have the option set FALSE. A routine, "find_console_vga_hose()", is used to find the graphics device which the machine's firmware believes is the console device, and it sets a global (pci_vga_hose) for later use in managing access to the device. This is called in "init_arch" on TITAN and TSUNAMI machines; MARVEL machines use a custom version of this routine because of extra complexity. A routine, "locate_and_init_vga()", is used to find the graphics device and set a global (pci_vga_hose) for later use in managing access to the device, in the case where "find_console_vga_hose" has failed. Various adjustments are made to the ioremap and ioportmap routines for detecting and translating "legacy" VGA register and memory references to the real PCI domain.

2007-05-31PCI: quirk disable MSI on via vt3351Jay Cliburn
The Via VT3351 APIC does not play well with MSI and unleashes a flood of APIC errors when MSI is used to deliver interrupts. The problem was recently exposed when the atl1 network device driver, which enables MSI by default, stimulated APIC errors on an Asus M2V mainboard, which employs the Via VT3351.

2007-05-29NOHZ: prevent multiplication overflow - stop timer for huge timeoutsThomas Gleixner
get_next_timer_interrupt() returns a delta of (LONG_MAX > 1) in case there is no timer pending. On 64 bit machines this results in a multiplication overflow in tick_nohz_stop_sched_tick(). Reported by: Dave Miller <davem@davemloft.net> Make the return value a constant and limit the return value to a 32 bit value. When the max timeout value is returned, we can safely stop the tick timer device. The max jiffies delta results in a 12 days timeout for HZ=1000. In the long term the get_next_timer_interrupt() code needs to be reworked to return ktime instead of jiffies, but we have to wait until the last users of the original NO_IDLE_HZ code are converted.

2007-05-29[SPARC64]: Eliminate NR_CPUS limitations.David S. Miller
Cheetah systems can have cpuids as large as 1023, although physical systems don't have that many cpus. Only three limitations existed in the kernel preventing arbitrary NR_CPUS values: 1) dcache dirty cpu state stored in page->flags on D-cache aliasing platforms. With some build time calculations and some build-time BUG checks on page->flags layout, this one was easily solved. 2) The cheetah XCALL delivery code could only handle a cpumask with up to 32 cpus set. Some simple looping logic clears that up too. 3) thread_info->cpu was a u8, easily changed to a u16. There are a few spots in the kernel that still put NR_CPUS sized arrays on the kernel stack, but that's not a sparc64 specific problem. Signed-off-by: David S. Miller <davem@davemloft.net>

2007-05-24[XFRM]: Allow packet drops during larval state resolution.David S. Miller
The current IPSEC rule resolution behavior we have does not work for a lot of people, even though technically it's an improvement from the -EAGAIN buisness we had before. Right now we'll block until the key manager resolves the route. That works for simple cases, but many folks would rather packets get silently dropped until the key manager resolves the IPSEC rules. We can't tell these folks to "set the socket non-blocking" because they don't have control over the non-block setting of things like the sockets used to resolve DNS deep inside of the resolver libraries in libc. With that in mind I coded up the patch below with some help from Herbert Xu which provides packet-drop behavior during larval state resolution, controllable via sysctl and off by default. This lays the framework to either: 1) Make this default at some point or... 2) Move this logic into xfrm{4,6}_policy.c and implement the ARP-like resolution queue we've all been dreaming of. The idea would be to queue packets to the policy, then once the larval state is resolved by the key manager we re-resolve the route and push the packets out. The packets would timeout if the rule didn't get resolved in a certain amount of time. Signed-off-by: David S. Miller <davem@davemloft.net>
