This check is very naive: we simply test if GCC invoked without "-mcpu=XXX" has ARC700 define set. In that case we think that GCC was built with "--with-cpu=arc700" and has libgcc built for ARC700. Otherwise if ARC700 is not defined we think that everythng was built for ARCv2. But in reality our life is much more interesting. 1. Regardless of GCC configuration (i.e. what we pass in "--with-cpu" it may generate code for any ARC core). 2. libgcc might be built with explicitly specified "--mcpu=YYY" That's exactly what happens in case of multilibbed toolchains: - GCC is configured with default settings - All the libs built for many different CPU flavors I.e. that check gets in the way of usage of multilibbed toolchains. And even non-multilibbed toolchains are affected. OpenEmbedded also builds GCC without "--with-cpu" because each and every target component later is compiled with explicitly set "-mcpu=ZZZ".

If there is no System.map file for "make modules_install", scripts/depmod.sh will silently exit with success, having done nothing. Since this is an unexpected situation, change it to report a Warning for the missing file. The behavior is not changed except for the Warning message. The (previous) silent success and new Warning can be reproduced by: $ make mrproper; make defconfig $ make modules; make modules_install and since System.map is produced by "make vmlinux", the steps above omit producing the System.map file.

When page-table entries are set, the compiler might optimize their assignment by using multiple instructions to set the PTE. This might turn into a security hazard if the user somehow manages to use the interim PTE. L1TF does not make our lives easier, making even an interim non-present PTE a security hazard. Using WRITE_ONCE() to set PTEs and friends should prevent this potential security hazard. I skimmed the differences in the binary with and without this patch. The differences are (obviously) greater when CONFIG_PARAVIRT=n as more code optimizations are possible. For better and worse, the impact on the binary with this patch is pretty small. Skimming the code did not cause anything to jump out as a security hazard, but it seems that at least move_soft_dirty_pte() caused set_pte_at() to use multiple writes.

Fix the cell specification mechanism to allow cells to be pre-created without having to specify at least one address (the addresses will be upcalled for). This allows the cell information preload service to avoid the need to issue loads of DNS lookups during boot to get the addresses for each cell (500+ lookups for the 'standard' cell list[*]). The lookups can be done later as each cell is accessed through the filesystem. Also remove the print statement that prints a line every time a new cell is added. [*] There are 144 cells in the list. Each cell is first looked up for an SRV record, and if that fails, for an AFSDB record. These get a list of server names, each of which then has to be looked up to get the addresses for that server.

This patch fixes it by adding a check to kvm_pv_send_ipi() against map->max_apic_id, ignoring destinations that are not present and delivering the rest. We also check whether or not map->phys_map[min + i] is NULL since the max_apic_id is set to the max apic id, some phys_map maybe NULL when apic id is sparse, especially kvm unconditionally set max_apic_id to 255 to reserve enough space for any xAPIC ID.

Consider the case L1 had a IRQ/NMI event until it executed VMLAUNCH/VMRESUME which wasn't delivered because it was disallowed (e.g. interrupts disabled). When L1 executes VMLAUNCH/VMRESUME, L0 needs to evaluate if this pending event should cause an exit from L2 to L1 or delivered directly to L2 (e.g. In case L1 don't intercept EXTERNAL_INTERRUPT). Usually this would be handled by L0 requesting a IRQ/NMI window by setting VMCS accordingly. However, this setting was done on VMCS01 and now VMCS02 is active instead. Thus, when L1 executes VMLAUNCH/VMRESUME we force L0 to perform pending event evaluation by requesting a KVM_REQ_EVENT. Note that above scenario exists when L1 KVM is about to enter L2 but requests an "immediate-exit". As in this case, L1 will disable-interrupts and then send a self-IPI before entering L2.

If trapping FPSIMD in the context of an AArch32 guest, it is critical to set FPEXC32_EL2.EN to 1 so that the trapping is taken to EL2 and not EL1. Conversely, it is just as critical *not* to set FPEXC32_EL2.EN to 1 if we're not going to trap FPSIMD, as we then corrupt the existing VFP state. Moving the call to __activate_traps_fpsimd32 to the point where we know for sure that we are going to trap ensures that we don't set that bit spuriously.

When triggering a CoW, we unmap the RO page via an MMU notifier (invalidate_range_start), and then populate the new PTE using another one (change_pte). In the meantime, we'll have copied the old page into the new one. The problem is that the data for the new page is sitting in the cache, and should the guest have an uncached mapping to that page (or its MMU off), following accesses will bypass the cache. In a way, this is similar to what happens on a translation fault: We need to clean the page to the PoC before mapping it. So let's just do that. This fixes a KVM unit test regression observed on a HiSilicon platform, and subsequently reproduced on Seattle.

Pull MIPS fix from Paul Burton: "A single fix for v4.19-rc3, resolving a problem with our VDSO data page for systems with dcache aliasing.

由 Peter Zijlstra 提交于
I turns out that the silly spawn kthread from worker was actually needed. clocksource_watchdog_kthread() cannot be called directly from clocksource_watchdog_work(), because clocksource_select() calls timekeeping_notify() which uses stop_machine(). One cannot use stop_machine() from a workqueue() due lock inversions wrt CPU hotplug. Revert the patch but add a comment that explain why we jump through such apparently silly hoops.
