When low memory doesn't reach HIGHMEM_START (e.g. up to 256MB at PA=0 is common) and highmem is present above HIGHMEM_START (e.g. on Malta the RAM overlayed by the IO region is aliased at PA=0x90000000), max_low_pfn will be initially calculated very large and then clipped down to HIGHMEM_START. This causes crashes when reading /sys/kernel/mm/page_idle/bitmap (i.e. CONFIG_IDLE_PAGE_TRACKING=y) when highmem is disabled. pfn_valid() will compare against max_mapnr which is derived from max_low_pfn when there is no highend_pfn set up, and will return true for PFNs right up to HIGHMEM_START, even though they are beyond the end of low memory and no page structs will actually exist for these PFNs. This is fixed by skipping high memory regions when initially calculating max_low_pfn if highmem is disabled, so it doesn't get clipped too high. We also clip regions which overlap the highmem boundary when highmem is disabled, so that max_pfn doesn't extend into highmem either.

Complement commit 80cbfad7 ("MIPS: Correct MIPS I FP context layout") and correct the way Floating Point General registers are stored in a signal context with MIPS I hardware. Use the S.D and L.D assembly macros to have pairs of SWC1 instructions and pairs of LWC1 instructions produced, respectively, in an arrangement which makes the memory representation of floating-point data passed compatible with that used by hardware SDC1 and LDC1 instructions, where available, regardless of the hardware endianness used. This matches the layout used by r4k_fpu.S, ensuring run-time compatibility for MIPS I software across all o32 hardware platforms. Define an EX2 macro to handle exceptions from both hardware instructions implicitly produced from S.D and L.D assembly macros. Signed-off-by: NMaciej W.

Sanitize FCSR Cause bit handling, following a trail of past attempts: * commit 42495484 ("MIPS: ptrace: Fix FP context restoration FCSR regression"), * commit 443c4403 ("MIPS: Always clear FCSR cause bits after emulation"), * commit 64bedffe ("MIPS: Clear [MSA]FPE CSR.Cause after notify_die()"), * commit b1442d39 ("MIPS: Prevent user from setting FCSR cause bits"), * commit b54d2901517d ("Properly handle branch delay slots in connection with signals."). Specifically do not mask these bits out in ptrace(2) processing and send a SIGFPE signal instead whenever a matching pair of an FCSR Cause and Enable bit is seen as execution of an affected context is about to resume. Only then clear Cause bits, and even then do not clear any bits that are set but masked with the respective Enable bits. Adjust Cause bit clearing throughout code likewise, except within the FPU emulator proper where they are set according to IEEE 754 exceptions raised as the operation emulated executed. Do so so that any IEEE 754 exceptions subject to their default handling are recorded like with operations executed by FPU hardware. Signed-off-by: NMaciej W.

Since commit 4bcc595c ("printk: reinstate KERN_CONT for printing continuation lines") the output from TLB dumps on MIPS has been pretty unreadable due to the lack of KERN_CONT markers. Use pr_cont to provide the appropriate markers & restore the expected output.

We have one critical section in the syscall entry path in which we switch from the userspace stack to kernel stack. In the event of an external interrupt, the interrupt code distinguishes between those two states by analyzing the value of sr7. If sr7 is zero, it uses the kernel stack. Therefore it's important, that the value of sr7 is in sync with the currently enabled stack. This patch now disables interrupts while executing the critical section. This prevents the interrupt handler to possibly see an inconsistent state which in the worst case can lead to crashes. Interestingly, in the syscall exit path interrupts were already disabled in the critical section which switches back to the userspace stack.

There is no need to trash sr2 and sr3 in the Light-weight syscall (LWS). sr2 already points to kernel space (it's zero in userspace, otherwise syscalls wouldn't work), and since the LWS code is executed in userspace, we can simply ignore to preload sr3.

Commit 41061cdb ("KVM: emulate: do not initialize memopp") removes a check for non-NULL under incorrect assumptions. An undefined instruction with a ModR/M byte with Mod=0 and R/M-5 (e.g. 0xc7 0x15) will attempt to dereference a null pointer here.

After a successful VM-entry with the "VMCS shadowing" VM-execution control set, the shadow VMCS referenced by the VMCS link pointer field in the current VMCS becomes active on the logical processor. A VMCS that is made active on more than one logical processor may become corrupted. Therefore, before an active VMCS can be migrated to another logical processor, the first logical processor must execute a VMCLEAR for the active VMCS. VMCLEAR both ensures that all VMCS data are written to memory and makes the VMCS inactive.

Since commit a545ab6a ("kvm: x86: add tsc_offset field to struct kvm_vcpu_arch", 2016-09-07) the offset between host and L1 TSC is cached and need not be fished out of the VMCS or VMCB. This means that we can implement adjust_tsc_offset_guest and read_l1_tsc entirely in generic code. The simplification is particularly significant for VMX code, where vmx->nested.vmcs01_tsc_offset was duplicating what is now in vcpu->arch.tsc_offset. Therefore the vmcs01_tsc_offset can be dropped completely. More importantly, this fixes KVM_GET_CLOCK/KVM_SET_CLOCK which, after commit 108b249c ("KVM: x86: introduce get_kvmclock_ns", 2016-09-01) called read_l1_tsc while the VMCS was not loaded. It thus returned bogus values on Intel CPUs.
