When we have virtio enabled, we must have real barriers since we may be running on an SMP machine (quite likely are, in fact), so the other process can be on another CPU. Since in any other case we don't really use DMA barriers, remove their override completely so real barriers will get used. In the future we might need them for other cases as well.

We currently do the time updates in the timer handler, even if we just call the timer handler ourselves. In basic mode we must in fact do it there since otherwise the OS timer signal won't move time forward, but in inf-cpu mode we don't need to, and it's harder to understand. Restrict the update there to basic mode, adding a comment, and do it before calling the timer_handler() in inf-cpu mode.

Periodic timers are broken, because the also only fire once. As it happens, Linux doesn't care because it only sets the timer to periodic very briefly during boot, and then switches it only between one-shot and off later. Nevertheless, fix the logic (we shouldn't even be looking at time_travel_timer_expiry unless the timer is enabled) and change the code to fire the timer periodically in periodic mode, in case it ever gets used in the future.

We do need to call the constructors for *modules*, and at least for KASAN in the future, we must call even the kernel constructors only later when the kernel has been initialized. Instead of relying on libc to call them, emit an empty section for libc and let the kernel's CONSTRUCTORS code do the rest of the job. Tested that it indeed doesn't work in modules, and does work after the fixes in both, with a few functions with __attribute__((constructor)) in both dynamic and static builds.

With the addition of bess support which uses connection oriented SEQPACKET sockets the vector routines can now encounter a "remote end closed the connection" scenario. This adds handling code to detect it in the TX path and the legacy RX path. There is no way to detect it in the vector RX path because that can legitimately return 0 even if the remote end has not closed the connection. As a result the detection is delayed until the first TX event after the close. Signed-off-by: NAnton Ivanov <anton.ivanov@cambridgegreys.com> Signed-off-by: NRichard Weinberger <richard@nod.at>

Pull x86 fixes from Thomas Gleixner: "A set of fixes for x86: - Fix the bogus detection of 32bit user mode for uretprobes which caused corruption of the user return address resulting in application crashes. In the uprobes handler in_ia32_syscall() is obviously always returning false on a 64bit kernel. Use user_64bit_mode() instead which works correctly. - Prevent large page splitting when ftrace flips RW/RO on the kernel text which caused iTLB performance issues. Ftrace wants to be converted to text_poke() which avoids the problem, but for now allow large page preservation in the static protections check when the change request spawns a full large page. - Prevent arch_dynirq_lower_bound() from returning 0 when the IOAPIC is configured via device tree. In the device tree case the GSI 1:1 mapping is meaningless therefore the lower bound which protects the GSI range on ACPI machines is irrelevant. Return the lower bound which the core hands to the function instead of blindly returning 0 which causes the core to allocate the invalid virtual interupt number 0 which in turn prevents all drivers from allocating and requesting an interrupt. - Remove the bogus initialization of LDR and DFR in the 32bit bigsmp APIC driver. That uses physical destination mode where LDR/DFR are ignored, but the initialization and the missing clear of LDR caused the APIC to be left in a inconsistent state on kexec/reboot. - Clear LDR when clearing the APIC registers so the APIC is in a well defined state. - Initialize variables proper in the find_trampoline_placement() code. - Silence GCC( build warning for the real mode part of the build" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mm/cpa: Prevent large page split when ftrace flips RW on kernel text x86/build: Add -Wnoaddress-of-packed-member to REALMODE_CFLAGS, to silence GCC9 build warning x86/boot/compressed/64: Fix missing initialization in find_trampoline_placement() x86/apic: Include the LDR when clearing out APIC registers x86/apic: Do not initialize LDR and DFR for bigsmp uprobes/x86: Fix detection of 32-bit user mode x86/apic: Fix arch_dynirq_lower_bound() bug for DT enabled machines

On embedded environments with hard memory limits it is a normal although rare case when skb can't be allocated on rx part under high traffic. In such OOM cases napi_complete_done() was not called. So the napi object became in an invalid state like it is "scheduled". Kernel do not re-schedules the poll of that napi object. Consequently, kernel can not remove that object the system hangs on `ifconfig down` waiting for a poll. We are fixing this by gracefully closing napi poll routine with correct invocation of napi_complete_done. This was reproduced with artificially failing the allocation of skb to simulate an "out of memory" error case and check that traffic does not get stuck.

Declaring threaded irq handler should also indicate the irq is oneshot. It is oneshot indeed, because HW implements irq automasking on trigger. Not declaring this causes some kernel configurations to fail on interface up, because request_threaded_irq returned an err code.
