2013-04-25regulator: mc13892: Fix MC13892_SWITCHERS0_SWxHI bit in set_voltage_selAxel Lin
It is necessary to clear MC13892_SWITCHERS0_SWxHI bit when set voltage to the voltage range from 1100000 to 1375000. Leaving MC13892_SWITCHERS0_SWxHI bit untouched may result in wrong voltage setting. For example, currently switch voltage from 1400000 to 1300000 will set the voltage to 1800000 because the HI bit is still set.

2013-04-25iscsi-target: Add iser network portal attributeNicholas Bellinger
This patch adds a new network portal attribute for iser, that lives under existing iscsi-target configfs layout at: /sys/kernel/config/target/iscsi/$TARGETNAME/$TPGT/np/$PORTAL/iser When lio_target_np_store_iser() is enabled, iscsit_tpg_add_network_portal() will attempt to start an rdma_cma network portal for iser-target, only if the external ib_isert module transport has been loaded. When disabled, iscsit_tpg_del_network_portal() will cease iser login service on the network portal, and release any external ib_isert module reference. v4 changes: - Add request_module for ib_isert to lio_target_np_store_iser() Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

2013-04-24vfio-pci: Use PCI_MSIX_TABLE_BIR, not PCI_MSIX_FLAGS_BIRMASKBjorn Helgaas
PCI_MSIX_FLAGS_BIRMASK is mis-named because the BIR mask is in the Table Offset register, not the flags ("Message Control" per spec) register. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Alex Williamson <alex.williamson@redhat.com>
2013-04-24USB: ftdi_sio: enable two UART ports on ST Microconnect LiteAdrian Thomasset
The FT4232H used in the ST Micro Connect Lite has four hi-speed UART ports. The first two ports are reserved for the JTAG interface. We enable by default ports 2 and 3 as UARTs (where port 2 is a conventional RS-232 UART) Signed-off-by: Adrian Thomasset <adrian.thomasset@st.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

fsreeze does not work for iso9660 filesystems. A ENOSUPP may be caught in the freeze case, but the subsequent thaw call would fail and leads to a false error.

2013-04-24efi: Check EFI revision in setup_efi_varsJosh Boyer
We need to check the runtime sys_table for the EFI version the firmware specifies instead of just checking for a NULL QueryVariableInfo. Older implementations of EFI don't have QueryVariableInfo but the runtime is a smaller structure, so the pointer to it may be pointing off into garbage. This is apparently the case with several Apple firmwares that support EFI 1.10, and the current check causes them to no longer boot. Fix based on a suggestion from Matthew Garrett.
