mmc: omap_hsmmc: pass IRQF_ONESHOT to request_threaded_irq

commit db35f83ef47b5f180f2670d11f5f93992314ea09 upstream.

The flag of IRQF_ONESHOT should be passed to request_threaded_irq,
otherwise the following failure message should be dumped because
hardware handler is defined as NULL:

[    3.383483] genirq: Threaded irq requested with handler=NULL and
!ONESHOT for irq 368
[    3.392730] omap_hsmmc: probe of omap_hsmmc.0 failed with error -22

The patch fixes one kernel hang bug which is caused by mmc card
probe failure and root device can't be brought up.

tile: fix bug where fls(0) was not returning 0

commit 9f1d62bed7f015d11b9164078b7fea433b474114 upstream.

This is because __builtin_clz(0) returns 64 for the "undefined" case
of 0, since the builtin just does a right-shift 32 and "clz" instruction.
So, use the alpha approach of casting to u32 and using __builtin_clzll().

intel-iommu: Add device info into list before doing context mapping

commit e2ad23d04c1304431ab5176c89b7b476ded2d995 upstream.

Add device info into list before doing context mapping, because device
info will be used by iommu_enable_dev_iotlb(). Without it, ATS won't get
enabled as it should be.

ATS, while a dubious decision from a security point of view, can be very
important for performance.

iommu: Fix off by one in dmar_get_fault_reason()

commit fefe1ed1398b81e3fadc92d11d91162d343c8836 upstream.

fault_reason - 0x20 == ARRAY_SIZE(irq_remap_fault_reasons) is
one past the end of the array.

ARM: 7365/1: drop unused parameter from flush_cache_user_range

commit 4542b6a0fa6b48d9ae6b41c1efeb618b7a221b2a upstream.

vma isn't used and flush_cache_user_range isn't a standard macro that
is used on several archs with the same prototype. In fact only unicore32
has a macro with the same name (with an identical implementation and no
in-tree users).

This is a part of a patch proposed by Dima Zavin (with Message-id:
1272439931-12795-1-git-send-email-dima@android.com) that didn't get
accepted.
