2012-05-16brcmsmac: read PCI vendor and device id only for PCI devicesHauke Mehrtens
If brcmsmac is used on non PCI(s) devices it should not try to access bus->host_pci. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Tested-by: Arend van Spriel <arend@broadcom.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2012-05-16brcmsmac: remove PCIe functions needed for PCIe core rev <= 10Hauke Mehrtens
The devices I know of are not using a PCIe core with rev <= 10. The BCM4718 uses a PCIe core with revision 14 and the BCM43224 uses a PCIe core with revision 15. This patch removes support for old PCIe core versions, which are not found on devices supported by brcmsmac.

2012-05-16brcmsmac: remove references to PCIHauke Mehrtens
There are no devices which are using bcma and have a PCI bus, just a PCIe bus or something else. bcma does not support PCI devices, so lets also remove PCI support from brcmsmac.

The lowest chip common version used on bcma based devices is 31 on the bcm4718 and 32 on the bcm4313, bcm43224, and bcm43225, so the support for the old versions could be removed.

2012-05-16ssb: remove rev from boardinfoHauke Mehrtens
Previously the rev contained the revision read from the pci config space and was used as board_rev in the wireless drivers. This is wrong the board_rev is only fetched from the sprom accordingly to the open source part of the Broadcom SDK and brcmsmac. This patch removes the rev from the boardinfo structure and uses the board_rev attribute from sprom instead. This attribute is filled by PCI, PCMCIA, SDIO and SoC code.

2012-05-16KVM: PPC: Book3S HV: Fix bug leading to deadlock in guest HPT updatesPaul Mackerras
When handling the H_BULK_REMOVE hypercall, we were forgetting to invalidate and unlock the hashed page table entry (HPTE) in the case where the page had been paged out. This fixes it by clearing the first doubleword of the HPTE in that case. This fixes a regression introduced in commit a92bce95f0 ("KVM: PPC: Book3S HV: Keep HPTE locked when invalidating"). The effect of the regression is that the host kernel will sometimes hang when under memory pressure. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2012-05-16powerpc/kvm: Fix VSID usage in 64-bit "PR" KVMBenjamin Herrenschmidt
The code forgot to scramble the VSIDs the way we normally do and was basically using the "proto VSID" directly with the MMU. This means that in practice, KVM used random VSIDs that could collide with segments used by other user space programs.

2012-05-16KVM: PPC: Book3S: PR: Fix hsrr codeAlexander Graf
When jumping back into the kernel to code that knows that it would be using HSRR registers instead of SRR registers, we need to make sure we pass it all information on where to jump to in HSRR registers. Unfortunately, we used r10 to store the information to distinguish between the HSRR and SRR case. That register got clobbered in between though, rendering the later comparison invalid. Instead, let's use cr1 to store this information. That way we don't need yet another register and everyone's happy. This fixes PR KVM on POWER7 bare metal for me.

2012-05-16KVM: PPC: Fix PR KVM on POWER7 bare metalAlexander Graf
When running on a system that is HV capable, some interrupts use HSRR SPRs instead of the normal SRR SPRs. These are also used in the Linux handlers to jump back to code after an interrupt got processed. Unfortunately, in our "jump back to the real host handler after we've done the context switch" code, we were only setting the SRR SPRs, rendering Linux to jump back to some invalid IP after it's processed the interrupt. This fixes random crashes on p7 opal mode with PR KVM for me. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-05-16KVM: PPC: Book3S: PR: Handle EMUL_ASSISTAlexander Graf
In addition to normal "priviledged instruction" traps, we can also receive "emulation assist" traps on newer hardware that has the HV bit set. Handle that one the same way as a privileged instruction, including the instruction fetching. That way we don't execute old instructions that we happen to still leave in that field when an emul assist trap comes. This fixes -M mac99 / -M g3beige on p7 bare metal for me.
