This patch changes the CPU_V7 configuration dependency to allow MACH_REALVIEW_EB. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-04-18RealView: Move more device address definitions to board-eb.hCatalin Marinas
The upcoming PB11MPCore and PB1176 have different memory maps and some of the definitions in platform.h are no longer common. This patch moves them to the board-eb.h file and updates their usage in realview_eb.c. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-04-18RealView: Move the UART definitions to EB specific filesCatalin Marinas
Since the PB1176 has different UART base addresses, this patch moves the definitions form platorm.h to board-eb.h. It also modifies uncompress.h to detect the platform type at run-time. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-04-18RealView: Move the timer definitions into the EB specific filesCatalin Marinas
This patch moves the timer definitions from platform.h into board-eb.h as they are different on PB11MPCore and PB1176. It also adds timerX_va_base variables in core.c which are set by the realview_eb_timer_init function before invoking realview_timer_init. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-04-18RealView: Move the flash definitions out of platform.hCatalin Marinas
This patch moves the patch definitions into board-eb.h and realview_eb.c (from core.c) as they are different on the PB11MPCore and PB1176 platforms. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

2008-03-25ACPI: fix Medion _PRT quirk (use "ISA_", not "ISA")Bjorn Helgaas
This fixes the builtin RTL8139 NIC on the Medion MD9580-F laptop. The BIOS reports the interrupt routing incorrectly. I recently added a quirk to work around this, and this patch fixes a typo in the quirk. We pad every ACPI pathname component to four characters, so ".ISA." will never match anything. We need ".ISA_." instead. Thank you Johann-Nikolaus Andreae <johann-nikolaus.andreae@nacs.de> for patiently testing this patch.

While backporting 72dc67a69690288538142df73a7e3ac66fea68dc, a gfn_to_page() call was duplicated instead of moved (due to an unrelated patch not being present in mainline).

2008-03-25KVM: VMX: Restore tss even on x86_64Avi Kivity
The vmx hardware state restore restores the tss selector and base address, but not its length. Usually, this does not matter since most of the tss contents is within the default length of 0x67. However, if a process is using ioperm() to grant itself I/O port permissions, an additional bitmap within the tss, but outside the default length is consulted. The effect is that the process will receive a SIGSEGV instead of transparently accessing the port. Fix by restoring the tss length. Note that i386 had this working already. Closes bugzilla 10246.

2008-03-24PCI: iova: lockdep false alarm fixMark Gross
lockdep goes off on the iova copy_reserved_iova() because it and a function it calls grabs locks in the from, and the to of the copy operation. The function grab locks of the same lock classes triggering the warning. The first lock grabbed is for the constant reserved areas that is never accessed after early boot. Technically you could do without grabbing the locks for the "from" structure its copying reserved areas from. But dropping the from locks to me looks wrong, even though it would be ok. The affected code only runs in early boot as its setting up the DMAR engines. This patch gives the reserved_ioval_list locks special lockdep classes.

2008-03-24USB: ehci: stop vt6212 bus hoggingRene Herman
The VIA VT6212 defaults to only waiting 1us between passes over EHCI's async ring, which hammers PCI badly ... and by preventing other devices from accessing the bus, causes problems like drops in IDE throughput, a problem that's been bugging users of those chips for several years. A (partial) datasheet for this chip eventually turned up, letting us see how to make it use a VIA-specific register to switch over to the the normal 10us value instead, as suggested by the EHCI specification Solution noted by Lev A. Melnikovsky. It's not clear whether this register exists on other VIA chips; we know that it's ineffective on the vt8235. So this patch only applies to chips that seem to be incarnations of the (discrete) vt6212. Signed-off-by: Rene Herman <rene.herman@gmail.com> Tested-by: Lev A.

2008-03-24sata_promise: fix hardreset hotplug events, take 2Mikael Pettersson
A Promise SATA controller will signal hotplug events when a hard reset (COMRESET) is done on a port. These events aren't masked by the driver, and the unexpected interrupts will cause a sequence of failed reset attempts util libata's EH finally gives up. This has not been a common problem so far, but the pending libata hardreset-by-default changes makes it a critical issue. The solution is to disable hotplug events before a reset, and to reenable them afterwards. (Promise's driver does this too.) This patch adds SATA-specific versions of ->freeze() and ->thaw() that also disable and enable hotplug events. PATA ports continue to use the old versions of ->freeze() and ->thaw(). Accesses to the hotplug register must be serialised via host->lock. We rely on ap->lock == &ap->host->lock and that libata takes this lock before ->freeze() and ->thaw(). Document this requirement. The interrupt handler is adjusted so its hotplug register accesses are inside the region protected by host->lock. Tested on various chips (SATA300TX4, SATA300TX2plus, SATAII150TX4, FastTrack TX4000) with various combinations of SATA and PATA disks, with and without the pending hardreset-by-default changes.
