Provide a PT map hook for HIGHPTE kernels to designate where they are mapping page tables. This information is required so the physical address of PTE updates can be determined; otherwise, the mm layer would have to carry the physical address all the way to each PTE modification callsite, which is even more hideous that the macros required to provide the proper hooks. So lets not mess up arch neutral code to achieve this, but keep the horror in an #ifdef HIGHPTE in include/asm-i386/pgtable.h. I had to use macros here because some types are not yet defined in all the include paths for this header. This patch is absolutely required for HIGHPTE kernels to operate properly with VMI.

In order to share the common code in tsc.c which does CPU Khz calibration, we need to make an accurate value of CPU speed available to the tsc.c code. This value loses a lot of precision in a VM because of the timing differences with real hardware, but we need it to be as precise as possible so the guest can make accurate time calculations with the cycle counters.

The custom_sched_clock hook is broken. The result from sched_clock needs to be in nanoseconds, not in CPU cycles. The TSC is insufficient for this purpose, because TSC is poorly defined in a virtual environment, and mostly represents real world time instead of scheduled process time (which can be interrupted without notice when a virtual machine is descheduled). To make the scheduler consistent, we must expose a different nature of time, that is scheduled time. So deprecate this custom_sched_clock hack and turn it into a paravirt-op, as it should have been all along. This allows the tsc.c code which converts cycles to nanoseconds to be shared by all paravirt-ops backends. It is unfortunate to add a new paravirt-op, but this is a very distinct abstraction which is clearly different for all virtual machine implementations, and it gets rid of an ugly indirect function which I ashamedly admit I hacked in to try to get this to work earlier, and then even got in the wrong units.

Critical bugfixes for the VMI-Timer code. 1) Do not setup a one shot alarm if we are keeping the periodic alarm armed. Additionally, since the periodic alarm can be run at a lower rate than HZ, let's fixup the guard to the no-idle-hz mode appropriately. This fixes the bug where the no-idle-hz mode might have a higher interrupt rate than the non-idle case. 2) The interrupt handler can no longer adjust xtime due to nested lock acquisition. Drop this. We don't need to check for wallclock time at every tick, it can be done in userspace instead. 3) Add a bypass to disable noidle operation. This is useful as a last minute workaround, or testing measure. 4) The code to skip the IO_APIC timer testing (no_timer_check) should be conditional on IO_APIC, not SMP, since UP kernels can have this configured in as well.

Currently we do not check for vma flags if sys_move_pages is called to move individual pages. If sys_migrate_pages is called to move pages then we check for vm_flags that indicate a non migratable vma but that still includes VM_LOCKED and we can migrate mlocked pages. Extract the vma_migratable check from mm/mempolicy.c, fix it and put it into migrate.h so that is can be used from both locations.

Currently sm501fb_crtsrc_store() won't allow the routing to be changed via echos from userspace in to the sysfs file. The reason for this is that the strnicmp() for both heads uses a sizeof() for the string length, which ends up being strlen() + 1 (\0 in the normal case, but the echo gives a newline, which is where the issue occurs), this then causes a mismatch and subsequently bails with the -EINVAL. In addition to this, the hardcoded lengths were then used for the store length that was returned, which ended up being erroneous and resulting in a write error. There's also no point in returning anything but the full length since it will -EINVAL out on a mismatch well before then anyways. sizeof("string") is great for making sure you have space in your buffer, but rather less so for string comparisons :-) Signed-off-by: NPaul Mundt <lethal@linux-sh.org> Acked-by: NBen Dooks <ben-linux@fluff.org> Cc: "Antonino A.

Remove the SMT-nice feature which idles sibling cpus on SMT cpus to facilitiate nice working properly where cpu power is shared. The idling of cpus in the presence of runnable tasks is considered too fragile, easy to break with outside code, and the complexity of managing this system if an architecture comes along with many logical cores sharing cpu power will be unworkable. Remove the associated per_cpu_gain variable in sched_domains used only by this code. Also: The reason is that with dynticks enabled, this code breaks without yet further tweaks so dynticks brought on the rapid demise of this code. So either we tweak this code or kill it off entirely. It was Ingo's preference to kill it off. Either way this needs to happen for 2.6.21 since dynticks has gone in.

Most drivers using GPIOs already know they are running on a system that supports the generic GPIO calls, because of other platform dependencies. But the generic GPIO-based LED and input button drivers can't know that. So this patch adds a Kconfig hook, GENERIC_GPIO, to mark the platforms where <asm/gpio.h> will do the right thing. Currently that's a bunch of ARMs, and AVR32; more are on the way. It also fixes a dependency bug for the gpio button input driver; it was wrong to start with, now it covers all platforms with GENERIC_GPIO.

Fix soft lockup with iSeries viocd driver, caused by eventually calling end_that_request_first() with nr_bytes 0. Some versions of hald do an SG_IO ioctl on the viocd device which becomes a request with hard_nr_sectors and hard_cur_sectors set to zero. Passing zero as the number of sectors to end_request() (which calls end_that_request_first()) causes an infinite loop when the bio is being freed. This patch makes sure that the zero is never passed. It only requires some number larger the the request size the terminate the loop. The lockup is triggered by hald, interrogating the device.

For devices that do not support msi-x we only support 1 interrupt. Therefore we can disable that one interrupt by disabling the msi capability itself. If we leave the intx interrupts disabled while we have the msi capability disabled no interrupts should be delivered from that device. Devices with just the minimal msi support (and thus hitting this code path) include things like the intel e1000 nic, so it looks like is going to be a fairly common case and thus important to get right.

由 Eric W. Biederman 提交于
enable/disable_msi_mode have several side effects which keeps them from being generally useful. So this patch replaces them with with two much more targeted functions: msi_set_enable and msix_set_enable. This patch makes pci_dev->msi_enabled and pci_dev->msix_enabled the definitive way to test if linux has enabled the msi capability, and has the appropriate msi data structures set up. This patch ensures that while writing the msi messages in save/restore and during device initialization we have the msi capability disabled so we don't get into races. The pci spec requires that we do not have the msi capability enabled and the msi messages unmasked while we write the messages. Completely disabling the capability is overkill but it is easy :) Care has been taken so we never have both a msi capability and intx enabled simultaneously. We haven't run into a problem yet but better safe then sorry. Signed-off-by: NEric W.

由 Eric W. Biederman 提交于
In some cases when we are not using msi we need a way to ensure that the hardware does not have an msi capability enabled. Currently the code has been calling disable_msi_mode to try and achieve that. However disable_msi_mode has several other side effects and is only available when msi support is compiled in so it isn't really appropriate. Instead this patch implements pci_msi_off which disables all msi and msix capabilities unconditionally with no additional side effects. pci_disable_device was redundantly clearing the bus master enable flag and clearing the msi enable bit. A device that is not allowed to perform bus mastering operations cannot generate intx or msi interrupt messages as those are essentially a special case of dma, and require bus mastering. So the call in pci_disable_device to disable msi capabilities was redundant. quirk_pcie_pxh also called disable_msi_mode and is updated to use pci_msi_off. Signed-off-by: NEric W.
