2007-06-03[AF_UNIX]: Make socket locking much less confusing.David S. Miller
The unix_state_*() locking macros imply that there is some rwlock kind of thing going on, but the implementation is actually a spinlock which makes the code more confusing than it needs to be. So use plain unix_state_lock and unix_state_unlock. Signed-off-by: David S. Miller <davem@davemloft.net>

2007-06-02[POWERPC] Fix return from pte_alloc_one() in out-of-memory caseAkinobu Mita
pte_alloc_one() is expected to return NULL if out of memory. But it returns virt_to_page(NULL), which is not NULL. This fixes it. Cc: Paul Mackerras <paulus@samba.org> Signed-off-by: Akinobu Mita <mita@fixstars.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-02[POWERPC] Fix possible access to free pagesBenjamin Herrenschmidt
I think we have a subtle race on ppc64 with the tlb batching. The common code expects tlb_flush() to actually flush any pending TLB batch. It does that because it delays all page freeing until after tlb_flush() is called, in order to ensure no stale reference to those pages exist in any TLB, thus causing potential access to the freed pages. However, our tlb_flush only triggers the RCU for freeing page table pages, it does not currently trigger a flush of a pending TLB/hash batch, which is, I think, an error. This fixes it.

Last of the "Section mismatch" errors from ia64 builds! acpi_map_pxm_to_node() is defined with attribute __cpuinit, but is called by "normal" kernel functions acpi_getnode() and acpi_map_cpu2node(). Commit f363d16fbb9374c0bd7f2757d412c287169094c9 moved the data structures on which this routine operates from __cpuinitdata to regular memory, so this routine can also move out of init space.

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.
