powerpc/pseries: Fix to handle slb resize across migration

2009-09-24T15:44:12+00:00

commit 46db2f86a3b2a94e0b33e0b4548fb7b7b6bdff66 upstream.

The SLB can change sizes across a live migration, which was not
being handled, resulting in possible machine crashes during
migration if migrating to a machine which has a smaller max SLB
size than the source machine. Fix this by first reducing the
SLB size to the minimum possible value, which is 32, prior to
migration. Then during the device tree update which occurs after
migration, we make the call to ensure the SLB gets updated. Also
add the slb_size to the lparcfg output so that the migration
tools can check to make sure the kernel has this capability
before allowing migration in scenarios where the SLB size will change.

PCI: Unhide the SMBus on the Compaq Evo D510 USDT

2009-09-24T15:44:11+00:00

commit 6b5096e4d4496e185cd1ada5d1b8e1d941c805ed upstream.

One more form factor for Compaq Evo D510, which needs the same quirk
as the other form factors. Apparently there's no hardware monitoring
chip on that one, but SPD EEPROMs, so it's still worth unhiding the
SMBus.

libata: fix off-by-one error in ata_tf_read_block()

2009-09-24T15:44:10+00:00

commit ac8672ea922bde59acf50eaa1eaa1640a6395fd2 upstream.

ata_tf_read_block() has off-by-one error when converting CHS address
to LBA.  The bug isn't very visible because ata_tf_read_block() is
used only when generating sense data for a failed RW command and CHS
addressing isn't used too often these days.

This problem was spotted by Atsushi Nemoto.

KVM: VMX: Fix cr8 exiting control clobbering by EPT

2009-09-24T15:44:08+00:00

commit 5fff7d270bd6a4759b6d663741b729cdee370257 upstream.

Don't call adjust_vmx_controls() two times for the same control.
It restores options that were dropped earlier.  This loses us the cr8
exit control, which causes a massive performance regression Windows x64.
