由 Heiko Carstens 提交于
Converting a 64 Bit TOD format value to nanoseconds means that the value must be divided by 4.096. In order to achieve that we multiply with 125 and divide by 512. When used within sched_clock() this triggers an overflow after appr. 417 days. Resulting in a sched_clock() return value that is much smaller than previously and therefore may cause all sort of weird things in subsystems that rely on a monotonic sched_clock() behaviour. To fix this implement a tod_to_ns() helper function which converts TOD values without overflow and call this function from both places that open coded the conversion: sched_clock() and kvm_s390_handle_wait().

commit b080935c kvm: Directly account vtime to system on guest switch also removed the irq_disable/enable around kvm guest switch, which is correct in itself. Unfortunately, there is a BUG ON that (correctly) checks for preemptible to cover the call to rcu later on. (Introduced with commit 8fa22068 KVM: make guest mode entry to be rcu quiescent state) This check might trigger depending on the kernel config. Lets make sure that no preemption happens during kvm_guest_enter. We can enable preemption again after the call to rcu_virt_note_context_switch returns. Please note that we continue to run s390 guests with interrupts enabled.

This is mostly a port of dbf62d50 ("ARM: mm: introduce L_PTE_VALID for page table entries") and 26ffd0d4 ("ARM: mm: introduce present, faulting entries for PAGE_NONE") from ARM, which makes use of present, faulting page table entries for page table entries mapped as PROT_NONE. The main difference with this implementation is that we can make use of the two pte type bits in order to avoid allocating a software bit for identifying PROT_NONE pages, instead reserving the 10b suffix for these types of mappings. This is required to prevent users from accessing such pages via syscalls such as read/write over a pipe.

This patch is an arm64 version of ce73ec6d ("powerpc/vdso: Remove redundant locking in update_vsyscall_tz()"). Timezone data is not protected, so the sequence counter is not required to ensure consistency. Furthermore, having multiple paths updating the counter leads to a race between update_vsyscall and update_vsyscall_tz, so remove the timezone sequence counting from both the kernel and the vdso.

This patch fixes some code that implements a work-around to a hardware bug in the ac97 controller on the pxa27x. A bug in the controller's warm reset functionality requires that the mfp used by the controller as the AC97_nRESET line be temporarily reconfigured as a generic output gpio (AF0) and manually held high for the duration of the warm reset cycle. This is what was done in the original code, but it was broken long ago by commit fb1bf8cd ([ARM] pxa: introduce processor specific pxa27x_assert_ac97reset()) which changed the mfp to a GPIO input instead of a high output. The fix requires the ac97 controller to obtain the gpio via gpio_request_one(), with arguments that configure the gpio as an output initially driven high. Tested on a palm treo 680 machine. Reportedly, this broken code only prevents a warm reset on hardware that lacks a pull-up on the line, which appears to be the case for me.
