For Realtek card reader, internal regsiter SD_CFG2 should be configured

The default value of SD_CFG2 is proper for writing data. But for reading

card reader may sample the response data from the card as good even if

Since some of the functions in sta2x11-mfd.c were almost identical
for the two existing platform devices, the following changes
have been performed to avoid further code duplication while
adding the apb-soc-regs driver:
* The sctl_regs and apbreg_regs fields in struct sta2x11_mfd
have been turned into just one array of pointers accessed by
device index.
* Platform probe methods have become one-liners invoking a
common probe with the device's index as second parameter.
* For loops have been inserted where the same operations
were performed for each of the two bars of a pci device.
* The apbreg_mask and sctl_mask functions were almost identical,
so they were turned into inline functions invoking a common
__sta2x11_mfd_mask() with the platform device's index as last
parameter. To do this, enum sta2x11_mfd_plat_dev has been declared in
sta2x11-mfd.h and more device types have been added to it.

mfd: Prevent STMPE from abusing mfd_add_devices' irq_base parameter
Originally IRQ incrementers were provided in some template resource
structures for keypad and touchscreen devices. These were passed as
IORESOURCE_IRQs to MFD core in the usual way. The true device IRQs
were instead added to the irq_base when mfd_add_devices was invoked.
This is clearly an abuse of the call, and does not scale when IRQ
Domains are brought into play. Before we can provide the STMPE with
its own IRQ Domain we must first fix this. This patche keeps most
of the driver's structure, keeping the template strategy. However,
instead of providing the IRQ as an increment to irq_base, we
dynamically populate the IORESOURCE_IRQ with the correct device IRQ.

Here we see that value written is as expected, but this write

Thanks to Roland & PureStorage team for helping to track down this

Subject: frv: split ret_from_fork, simplify kernel_thread() a lot
The problem is that the userspace registers are completely cleared when a
kernel thread is created and all subsequent user threads are then copied from
that. Unfortunately, however, the TBR and PSR registers are restored from the
pt_regs and the values they should be set to are clobbered by the memset.
Instead, copy across the old user registers as normal, and then merely alter
GR8 and GR9 in it if we're going to execute a kernel thread.

FRV: Fix the preemption handling
Fix the preemption handling in FRV code where the PREEMPT_ACTIVE value is
incorrectly loaded into the threadinfo flags rather than the threadinfo
preemption count.
Unfortunately, the code cannot be simply converted to use
preempt_schedule_irq() as is because FRV uses virtual interrupt disablement to
cut down on the cost of actually disabling interrupts and thus
local_irq_enable() doesn't actually enable interrupts.
