* fb_defio: add first_io callbackHeiko Stübner2012-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | With this optional callback the driver is notified when the first page is entered into the pagelist and a new deferred_io call is scheduled. A possible use-case for this is runtime-pm. In the first_io call pm_runtime_get() could be called, which starts an asynchronous runtime_resume of the device. In the deferred_io callback a call to pm_runtime_barrier() makes the sure, the device is resumed by then and a pm_runtime_put() may put the device back to sleep. Also, some SoCs may use the runtime-pm system to determine if they are able to enter deeper idle states. Therefore it is necessary to keep the use-count from the first written page until the conclusion of the screen update, to prevent the system from going to sleep before completing the pending update. Two users of defio were using kmalloc to allocate the structure. These allocations are changed to kzalloc, to prevent uninitialised .first_io members in those drivers.

| | | | | | | | | | | | | There were two problems in this code: failure of the setup function should free locally allocated resources like other nearby failures, and the test if (&info->cmap) can never be false. To generally clean things up, this patch reorders the error handling code at the failed label and adds labels so that the conditionals are not necessary.

It is beneficial to improve analog characteristics. - TX terminal registor is 50 Ohm. - Reference clock of PHY is 24 MHz. - Power source for TX digital logic is 1.0625 V. - Power source for internal clock driver is 1.0625 V. - PLL VCO range setting is 600 uA. - Power down ring osc is turned off. - AUX terminal resistor is 50 Ohm. - AUX channel current is 8 mA and multiplied by 2. - TX channel output amplitude is 400 mV.

* ARM: s3c64xx: Decouple lcd type from display controller window dataThomas Abraham2012-04-09
| | | | | | | | | | | | | | | | | | The display controller window data should contain window configuration data for only one type of lcd panel. So, for real6410 and mini6410 boards, split the existing display controller window data, which contains window configuration data for two different types of lcd panels, into two seperate instances and register one of them depending on the type of the lcd panel detected at runtime. This is a prerequisite change for a subsequent commit that reorders the platform data of display controller by moving video interface timing out of window setup data.

* video: s3c-fb: move video interface timing out of window setup dataThomas Abraham2012-04-09
| | | | | | | | | | | | | | | | The video interface timing is independent of the window setup data. The resolution of the window can be smaller than that of the lcd panel to which the video data is output. So move the video timing data from the per-window setup data to the platform specific section in the platform data. This also removes the restriction that atleast one window should have the same resolution as that of the panel attached.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On PPC, CR2-CR4 are nonvolatile, thus have to be saved across function calls. We didn't respect that for any architecture until Paul spotted it in his patch for Book3S-HV. This patch saves/restores CR for all KVM capable PPC hosts.

| | * | KVM: PPC: Book3S HV: Save and restore CR in __kvmppc_vcore_entryPaul Mackerras2012-04-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ABI specifies that CR fields CR2--CR4 are nonvolatile across function calls. Currently __kvmppc_vcore_entry doesn't save and restore the CR, leading to CR2--CR4 getting corrupted with guest values, possibly leading to incorrect behaviour in its caller. This adds instructions to save and restore CR at the points where we save and restore the nonvolatile GPRs.

In that situation, ri is not really defined and probably points to the list head. This will happen every time if the free_linears list is empty, for instance. This led to a NULL pointer dereference crash in memset on POWER7 while trying to allocate an HPT in the case where no HPTs were preallocated. This fixes it by using a separate variable for the return value from the loop iterator.

Also, on PPC32 we can not use get_user/put_user for 64bit wide variables, as there is no single instruction that could load or store variables that big. So instead, we have to use copy_from/to_user which works everywhere.

While it's trivial to provide an SHmedia version of dwarf_read_arch_reg(), the general sh64 case is more complicated in that the TLB miss handler uses a locked down set of registers for optimization (including the frame pointer) which we need for the unwind table generation. While freeing up the frame pointer for use in the TLB miss handler is reasonably straightforward, it's still more trouble than it's worth, so we simply restrict the unwinder to 32-bit for now.

This adds the CAP_SYS_ADMIN check to both dmesg_restrict and kptr_restrict, since both are sensitive.
