* add new_id to PCMCIA driversBernhard Walle2007-05-071-0/+6
| | | | | | | | | | | | | | | | | | | PCI drivers have the new_id file in sysfs which allows new IDs to be added at runtime. The advantage is to avoid re-compilation of a driver that works for a new device, but it's ID table doesn't contain the new device. This mechanism is only meant for testing, after the driver has been tested successfully, the ID should be added in source code so that new revisions of the kernel automatically detect the device. The implementation follows the PCI implementation. The interface is documented in Documentation/pcmcia/driver.txt. Computations should be done in userspace, so the sysfs string contains the raw structure members for matching.

* slab: introduce kreallocPekka Enberg2007-05-071-1/+2
| | | | | | | | | | | | | | | This introduce krealloc() that reallocates memory while keeping the contents unchanged. The allocator avoids reallocation if the new size fits the currently used cache. I also added a simple non-optimized version for mm/slob.c for compatibility.

* Revert "[PATCH] x86: __pa and __pa_symbol address space separation"Linus Torvalds2007-05-072-13/+9
| | | | | | | | | | | | | | | | | | | | | | | This was broken. It adds complexity, for no good reason. Rather than separate __pa() and __pa_symbol(), we should deprecate __pa_symbol(), and preferably __pa() too - and just use "virt_to_phys()" instead, which is more readable and has nicer semantics. However, right now, just undo the separation, and make __pa_symbol() be the exact same as __pa(). That fixes the bugs this patch introduced, and we can do the fairly obvious cleanups later. Do the new __phys_addr() function (which is now the actual workhorse for the unified __pa()/__pa_symbol()) as a real external function, that way all the potential issues with compile/link-time optimizations of constant symbol addresses go away, and we can also, if we choose to, add more sanity-checking of the argument.

| * | KVM: Avoid guest virtual addresses in string pio userspace interfaceAvi Kivity2007-05-031-9/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current string pio interface communicates using guest virtual addresses, relying on userspace to translate addresses and to check permissions. This interface cannot fully support guest smp, as the check needs to take into account two pages at one in case an unaligned string transfer straddles a page boundary. Change the interface not to communicate guest addresses at all; instead use a buffer page (mmaped by userspace) and do transfers there. The kernel manages the virtual to physical translation and can perform the checks atomically by taking the appropriate locks. Signed-off-by: Avi Kivity <avi@qumranet.com>
| * | KVM: Allow kernel to select size of mmap() bufferAvi Kivity2007-05-031-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | This allows us to store offsets in the kernel/user kvm_run area, and be sure that userspace has them mapped. As offsets can be outside the kvm_run struct, userspace has no way of knowing how much to mmap. Signed-off-by: Avi Kivity <avi@qumranet.com>
| * | KVM: Add guest mode signal maskAvi Kivity2007-05-031-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Allow a special signal mask to be used while executing in guest mode. This allows signals to be used to interrupt a vcpu without requiring signal delivery to a userspace handler, which is quite expensive. Userspace still receives -EINTR and can get the signal via sigwait(). Signed-off-by: Avi Kivity <avi@qumranet.com>
| * | KVM: Add a special exit reason when exiting due to an interruptAvi Kivity2007-05-031-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | This is redundant, as we also return -EINTR from the ioctl, but it allows us to examine the exit_reason field on resume without seeing old data. Signed-off-by: Avi Kivity <avi@qumranet.com>
| * | KVM: Fold kvm_run::exit_type into kvm_run::exit_reasonAvi Kivity2007-05-031-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, userspace is told about the nature of the last exit from the guest using two fields, exit_type and exit_reason, where exit_type has just two enumerations (and no need for more). So fold exit_type into exit_reason, reducing the complexity of determining what really happened. Signed-off-by: Avi Kivity <avi@qumranet.com>

| * | KVM: Handle cpuid in the kernel instead of punting to userspaceAvi Kivity2007-05-031-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | KVM used to handle cpuid by letting userspace decide what values to return to the guest. We now handle cpuid completely in the kernel. We still let userspace decide which values the guest will see by having userspace set up the value table beforehand (this is necessary to allow management software to set the cpu features to the least common denominator, so that live migration can work). The motivation for the change is that kvm kernel code can be impacted by cpuid features, for example the x86 emulator. Signed-off-by: Avi Kivity <avi@qumranet.com>
| * | KVM: Do not communicate to userspace through cpu registers during PIOAvi Kivity2007-05-031-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently when passing the a PIO emulation request to userspace, we rely on userspace updating %rax (on 'in' instructions) and %rsi/%rdi/%rcx (on string instructions). This (a) requires two extra ioctls for getting and setting the registers and (b) is unfriendly to non-x86 archs, when they get kvm ports. So fix by doing the register fixups in the kernel and passing to userspace only an abstract description of the PIO to be done. Signed-off-by: Avi Kivity <avi@qumranet.com>
| * | KVM: Use a shared page for kernel/user communication when runing a vcpuAvi Kivity2007-05-031-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of passing a 'struct kvm_run' back and forth between the kernel and userspace, allocate a page and allow the user to mmap() it.

CKEN24_CAMERA --> CKEN_CAMERA The reasons for the change of these defitions are: 1. they do not scale - they are currently valid for pxa2xx, but definitely not valid for pxa3xx, e.g., pxa3xx has bit 3 for camera instead of bit 24 2. they are unnecessary - the peripheral name within the definition has already announced its usage, we don't need those bit numbers to know which peripheral we are going to enable/disable clock for 3. they are inconvenient - think about this: a driver programmer for pxa has to remember which bit in the CKEN register to turn on/off Another change in the patch is to make the definitions equal to its clock bit index, so that #define CKEN_CAMERA (24) instead of #define CKEN_CAMERA (1 << 24) this change, however, will add a run-time bit shift operation in pxa_set_cken(), but the benefit of this change is that it scales when bit index exceeds 32, e.g., pxa3xx has two registers CKENA and CKENB, totally 64 bit for this, suppose CAMERA clock enabling bit is CKENB:10, one can simply define CKEN_CAMERA to be (32 + 10) and so that pxa_set_cken() need minimum change to adapt to that.

The driver i2c-pxa doesn't set the class member in i2c_adapter, which is used to register the I2C adapter. The hwmon (sensors) drivers (e.g. adm1021) that are connected to a i2c-pxa adapter don't attach because they expect that the adapter supports class I2C_CLASS_HWMON. This patch adds functionality to allow platforms to set the class and pass it as platform_data to the i2c-pxa driver. Sample usage in platform code: static struct i2c_pxa_platform_data my_i2c_platform_data = { .class = I2C_CLASS_HWMON }; static void __init my_platform_init(void) { (void) platform_add_devices(devices, ARRAY_SIZE(devices)); pxa_set_i2c_info(&my_i2c_platform_data); } Signed-off-by: Matej Kenda <matej.kenda@hermes-softlab.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
