2010-07-16[ARM] Orion: DNS-323 C1 requires phylibMartin Michlmayr
The code to support the DNS-323 rev C1 added a call to phy_register_fixup_for_uid() and therefore phylib has to be built in. Signed-off-by: Martin Michlmayr <tbm@cyrius.com> Signed-off-by: Nicolas Pitre <nico@fluxnic.net>

2010-07-16leds: add LED driver for Network Space v2 LEDsSimon Guinot
This patch add a LED class driver for the dual-GPIO LEDs found on the Network Space v2 board (and parents). This include Internet Space v2, Network Space (Max) v2 and d2 Network v2 boards. This dual-GPIO LED is wired to a CPLD and can blink in relation with the SATA activity. The driver expose this capability through a "sata" sysfs attribute.

2010-07-16[ARM] orion5x: Fix soft-reset for some platformsBenjamin Herrenschmidt
Some platforms, such as the DNS-323 rev C requires the soft reset line to be toggled on and back off for the reset to work. Note: The choice of 200ms delay comes from the 2.6.12 based vendor kernel. It seems to be a -lot- though and I had my device working fine with much smaller delays but better safe...

2010-07-16[ARM] orion5x: Set links to solid on D-Link DNS-323Martin Michlmayr
Among other changes, commit b2a731aa ("D-link DNS-323 revision A1 power LED") changed the default behaviour of the power LED from solid to blinking. This was done to match the original DNS-323 firmware which blinks during the boot process and sets the LED to solid when booting has completed. However, the downside of this behaviour is that it requires userland code to change the LED, even for those who don't care about the behaviour of the original firmware. Therefore, change it to solid again and let those who care about the original behaviour change the behaviour from userland.

2010-07-16x86, pci, mrst: Add extra sanity check in walking the PCI extended cap chainJacob Pan
The fixed bar capability structure is searched in PCI extended configuration space. We need to make sure there is a valid capability ID to begin with otherwise, the search code may stuck in a infinite loop which results in boot hang. This patch adds additional check for cap ID 0, which is also invalid, and indicates end of chain. End of chain is supposed to have all fields zero, but that doesn't seem to always be the case in the field. Suggested-by: "H.

2010-07-16x86: Fix x2apic preenabled system with kexecYinghai Lu
Found one x2apic system kexec loop test failed when CONFIG_NMI_WATCHDOG=y (old) or CONFIG_LOCKUP_DETECTOR=y (current tip) first kernel can kexec second kernel, but second kernel can not kexec third one. it can be duplicated on another system with BIOS preenabled x2apic. First kernel can not kexec second kernel. It turns out, when kernel boot with pre-enabled x2apic, it will not execute disable_local_APIC on shutdown path. when init_apic_mappings() is called in setup_arch, it will skip setting of apic_phys when x2apic_mode is set. ( x2apic_mode is much early check_x2apic()) Then later, disable_local_APIC() will bail out early because !apic_phys. So check !x2apic_mode in x2apic_mode in disable_local_APIC with !apic_phys. another solution could be updating init_apic_mappings() to set apic_phys even for preenabled x2apic system. Actually even for x2apic system, that lapic address is mapped already in early stage. BTW: is there any x2apic preenabled system with apicid of boot cpu > 255?

2010-07-16PCI: fall back to original BIOS BAR addressesBjorn Helgaas
If we fail to assign resources to a PCI BAR, this patch makes us try the original address from BIOS rather than leaving it disabled. Linux tries to make sure all PCI device BARs are inside the upstream PCI host bridge or P2P bridge apertures, reassigning BARs if necessary. Windows does similar reassignment. Before this patch, if we could not move a BAR into an aperture, we left the resource unassigned, i.e., at address zero. Windows leaves such BARs at the original BIOS addresses, and this patch makes Linux do the same. This is a bit ugly because we disable the resource long before we try to reassign it, so we have to keep track of the BIOS BAR address somewhere. For lack of a better place, I put it in the struct pci_dev. I think it would be cleaner to attempt the assignment immediately when the claim fails, so we could easily remember the original address. But we currently claim motherboard resources in the middle, after attempting to claim PCI resources and before assigning new PCI resources, and changing that is a fairly big job.

2010-07-16ARM: OMAP: Cleanup OMAP FB SDRAM reservationRussell King
The logic in this file is rather convoluted, but essentially: 1. region type 0 is SDRAM 2. referring to the code fragment if (set_fbmem_region_type(&rg, OMAPFB_MEMTYPE_SDRAM, sdram_start, sdram_size) < 0 || (rg.type != OMAPFB_MEMTYPE_SDRAM)) continue; - if rg.type is not OMAPFB_MEMTYPE_SDRAM, set_fbmem_region_type() returns zero immediately (since rg.type is non-zero), and so we 'continue'. - if rg.type is OMAPFB_MEMTYPE_SDRAM, and rg.paddr is zero, we fall through. - if rg.type is OMAPFB_MEMTYPE_SDRAM, and the region lies within SDRAM, we fall through. - if rg.type is OMAPFB_MEMTYPE_SDRAM, and the region is not within SDRAM, we 'continue'. 3. check_fbmem_region seems unnecessary. - we know rg.type is OMAPFB_MEMTYPE_SDRAM - we can check rg.size independently - bootmem_reserve() can check for overlapping reservations itself - we've already validated that the requested region lies within SDRAM. 4. avoid BUG()ing if the region entry is already set; print an error, and mark the configuration invalid - at least we'll continue booting so the error message has a chance of being logged/visible via serial console. With these changes in place, it makes the code much easier to understand and hence easier to convert to LMB. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2010-07-15x86: Force HPET readback_cmp for all ATI chipsetsThomas Gleixner
commit 30a564be (x86, hpet: Restrict read back to affected ATI chipset) restricted the workaround for the HPET bug to SMX00 chipsets. This was reasonable as those were the only ones against which we ever got a bug report. Stephan Wolf reported now that this patch breaks his IXP400 based machine. Though it's confirmed to work on other IXP400 based systems. To error out on the safe side, we force the HPET readback workaround for all ATI SMbus class chipsets.
