IB/ipath: Remove support for QLogic PCIe QLE devices The ib_qib driver is taking over support for QLogic PCIe QLE devices, so remove support for them from ib_ipath. The ib_ipath driver now supports only the obsolete QLogic Hyper-Transport IB host channel adapter (model QHT7140).

including InfiniBand verbs support. This driver allows these
devices to be used with both kernel upper level protocols such
as IP-over-InfiniBand as well as with userspace applications
(in conjunction with InfiniBand userspace access).

For QLogic PCIe QLE based cards, use the QIB driver instead.
x86/mm/pat, drivers/infiniband/ipath: Use arch_phys_wc_add() and require PAT disabled We are burrying direct access to MTRR code support on x86 in order to take advantage of PAT. In the future, we also want to make the default behaviour of ioremap_nocache() to use strong UC, use of mtrr_add() on those systems would make write-combining void. In order to help both enable us to later make strong UC default and in order to phase out direct MTRR access code port the driver over to arch_phys_wc_add() and annotate that the device driver requires systems to boot with PAT disabled, with the 'nopat' kernel parameter. This is a workable compromise given that the ipath device driver powers the old HTX bus cards that only work in AMD systems, while the newer IB/qib device driver powers all PCI-e cards. The ipath device driver is obsolete, hardware is hard to find and because of this its a reasonable compromise to require users of ipath to boot with 'nopat'. Signed-off-by: Luis R.

If you have this hardware you will need to boot with PAT disabled
on your x86-64 systems, use the nopat kernel parameter.
