* mm: remove gcc workaroundNick Piggin2007-05-07
| | | | | | | | | | | | Minimum gcc version is 3.2 now. However, with likely profiling, even modern gcc versions cannot always eliminate the call. Replace the placeholder functions with the more conventional empty static inlines, which should be optimal for everyone.

* Add apply_to_page_range() which applies a function to a pte rangeJeremy Fitzhardinge2007-05-07
| | | | | | | | | | | | | | | | | | | | | | | | Add a new mm function apply_to_page_range() which applies a given function to every pte in a given virtual address range in a given mm structure. This is a generic alternative to cut-and-pasting the Linux idiomatic pagetable walking code in every place that a sequence of PTEs must be accessed. Although this interface is intended to be useful in a wide range of situations, it is currently used specifically by several Xen subsystems, for example: to ensure that pagetables have been allocated for a virtual address range, and to construct batched special pagetable update requests to map I/O memory (in ioremap()).

* serial: define FIXED_PORT flag for serial_coreDavid Gibson2007-05-07
| | | | | | | | | | | | | | | | | | | | | | | | At present, the serial core always allows setserial in userspace to change the port address, irq and base clock of any serial port. That makes sense for legacy ISA ports, but not for (say) embedded ns16550 compatible serial ports at peculiar addresses. In these cases, the kernel code configuring the ports must know exactly where they are, and their clocking arrangements (which can be unusual on embedded boards). It doesn't make sense for userspace to change these settings. Therefore, this patch defines a UPF_FIXED_PORT flag for the uart_port structure. If this flag is set when the serial port is configured, any attempts to alter the port's type, io address, irq or base clock with setserial are ignored. In addition this patch uses the new flag for on-chip serial ports probed in arch/powerpc/kernel/legacy_serial.c, and for other hard-wired serial ports probed by drivers/serial/of_serial.c.

* serial driver PMC MSP71xxMarc St-Jean2007-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Serial driver patch for the PMC-Sierra MSP71xx devices. There are three different fixes: 1 Fix for DesignWare APB THRE errata: In brief, this is a non-standard 16550 in that the THRE interrupt will not re-assert itself simply by disabling and re-enabling the THRI bit in the IER, it is only re-enabled if a character is actually sent out. It appears that the "8250-uart-backup-timer.patch" in the "mm" tree also fixes it so we have dropped our initial workaround. This patch now needs to be applied on top of that "mm" patch. 2 Fix for Busy Detect on LCR write: The DesignWare APB UART has a feature which causes a new Busy Detect interrupt to be generated if it's busy when the LCR is written. This fix saves the value of the LCR and rewrites it after clearing the interrupt. 3 Workaround for interrupt/data concurrency issue: The SoC needs to ensure that writes that can cause interrupts to be cleared reach the UART before returning from the ISR. This fix reads a non-destructive register on the UART so the read transaction completion ensures the previously queued write transaction has also completed.

* add new_id to PCMCIA driversBernhard Walle2007-05-07
| | | | | | | | | | | | | | | | | | | 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.

* Revert "[PATCH] x86: __pa and __pa_symbol address space separation"Linus Torvalds2007-05-07
| | | | | | | | | | | | | | | | | | | | | | | 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 Kivity2007-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Kivity2007-05-03
| | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | KVM: Add a special exit reason when exiting due to an interruptAvi Kivity2007-05-03

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Kivity2007-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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>
