2021-02-09KVM: SVM: Remove an unnecessary forward declarationSean Christopherson
Drop a defunct forward declaration of svm_complete_interrupts(). No functional change intended. Signed-off-by: Sean Christopherson <seanjc@google.com> Message-Id: <20210205005750.3841462-3-seanjc@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2021-02-09KVM: SVM: Move AVIC vCPU kicking snippet to helper functionSean Christopherson
Add a helper function to handle kicking non-running vCPUs when sending virtual IPIs. A future patch will change SVM's interception functions to take @vcpu instead of @svm, at which piont declaring and modifying 'vcpu' in a case statement is confusing, and potentially dangerous.

2021-02-09KVM: x86: Restore all 64 bits of DR6 and DR7 during RSM on x86-64Sean Christopherson
Restore the full 64-bit values of DR6 and DR7 when emulating RSM on x86-64, as defined by both Intel's SDM and AMD's APM. Note, bits 63:32 of DR6 and DR7 are reserved, so this is a glorified nop unless the SMM handler is poking into SMRAM, which it most definitely shouldn't be doing since both Intel and AMD list the DR6 and DR7 fields as read-only.

2021-02-09KVM: x86: Remove misleading DR6/DR7 adjustments from RSM emulationSean Christopherson
Drop the DR6/7 volatile+fixed bits adjustments in RSM emulation, which are redundant and misleading. The necessary adjustments are made by kvm_set_dr(), which properly sets the fixed bits that are conditional on the vCPU model. Note, KVM incorrectly reads only bits 31:0 of the DR6/7 fields when emulating RSM on x86-64. On the plus side for this change, that bug makes removing "& DRx_VOLATILE" a nop.

2021-02-09Revert "mips: Manually call fdt_init_reserved_mem() method"Serge Semin
This reverts commit 3751cbda8f223549d7ea28803cbec8ac87e43ed2. Originally the patch was created to fix the reserved-memory DT-node parsing failure on the early stages of the platform memory initialization. That happened due to the two early memory allocators utilization that time: bootmem and memblock. At first the platform-specific memory mapping array was initialized. Then the early_init_fdt_scan_reserved_mem() was called, which couldn't fully parse the "reserved-memory" DT-node since neither memblock nor bootmem allocators hadn't been initialized at that stage, so the fdt_init_reserved_mem() method failed on the memory allocation calls. Only after that the platform-specific memory mapping were used to create proper bootmem and memblock structures and let the early memory allocations work. That's why we had to call the fdt_init_reserved_mem() method one more time to retry the initialization of the features like CMA. The necessity to have that fix was disappeared after the full memblock support had been added to the MIPS kernel and all plat_mem_setup() had been fixed to add the memory regions right into the memblock memory pool. Let's revert that patch then especially after having Paul reported that the second fdt_init_reserved_mem() call causes the reserved memory pool being created twice bigger than implied.

In a bus remove function the passed device is always valid, so there is no need to check for it being NULL. (Side note: The check for port being non-NULL is broken anyhow, because to_usb_serial_port() is a wrapper around container_of() for a member that is not the first one. So port can hardly become NULL.)

2021-02-09KVM: Use kvm_pfn_t for local PFN variable in hva_to_pfn_remapped()Sean Christopherson
Use kvm_pfn_t, a.k.a. u64, for the local 'pfn' variable when retrieving a so called "remapped" hva/pfn pair. In theory, the hva could resolve to a pfn in high memory on a 32-bit kernel. This bug was inadvertantly exposed by commit bd2fae8da794 ("KVM: do not assume PTE is writable after follow_pfn"), which added an error PFN value to the mix, causing gcc to comlain about overflowing the unsigned long. arch/x86/kvm/../../../virt/kvm/kvm_main.c: In function ‘hva_to_pfn_remapped’: include/linux/kvm_host.h:89:30: error: conversion from ‘long long unsigned int’ to ‘long unsigned int’ changes value from ‘9218868437227405314’ to ‘2’ [-Werror=overflow] 89 | #define KVM_PFN_ERR_RO_FAULT (KVM_PFN_ERR_MASK + 2) | ^ virt/kvm/kvm_main.c:1935:9: note: in expansion of macro ‘KVM_PFN_ERR_RO_FAULT’ Cc: stable@vger.kernel.org Fixes: add6a0cd1c5b ("KVM: MMU: try to fix up page faults before giving up") Signed-off-by: Sean Christopherson <seanjc@google.com> Message-Id: <20210208201940.1258328-1-seanjc@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2021-02-09mm: provide a saner PTE walking API for modulesPaolo Bonzini
Currently, the follow_pfn function is exported for modules but follow_pte is not. However, follow_pfn is very easy to misuse, because it does not provide protections (so most of its callers assume the page is writable!) and because it returns after having already unlocked the page table lock. Provide instead a simplified version of follow_pte that does not have the pmdpp and range arguments. The older version survives as follow_invalidate_pte() for use by fs/dax.c.

2021-02-09MIPS: compressed: fix build with enabled UBSANAlexander Lobakin
Commit 1e35918ad9d1 ("MIPS: Enable Undefined Behavior Sanitizer UBSAN") added a possibility to build the entire kernel with UBSAN instrumentation for MIPS, with the exception for VDSO. However, self-extracting head wasn't been added to exceptions, so this occurs: mips-alpine-linux-musl-ld: arch/mips/boot/compressed/decompress.o: in function `FSE_buildDTable_wksp': decompress.c:(.text.FSE_buildDTable_wksp+0x278): undefined reference to `__ubsan_handle_shift_out_of_bounds' mips-alpine-linux-musl-ld: decompress.c:(.text.FSE_buildDTable_wksp+0x2a8): undefined reference to `__ubsan_handle_shift_out_of_bounds' mips-alpine-linux-musl-ld: decompress.c:(.text.FSE_buildDTable_wksp+0x2c4): undefined reference to `__ubsan_handle_shift_out_of_bounds' mips-alpine-linux-musl-ld: arch/mips/boot/compressed/decompress.o: decompress.c:(.text.FSE_buildDTable_raw+0x9c): more undefined references to `__ubsan_handle_shift_out_of_bounds' follow Add UBSAN_SANITIZE := n to mips/boot/compressed/Makefile to exclude it from instrumentation scope and fix this issue.

2021-02-09MIPS: relocatable: Use __kaslr_offset in show_kernel_relocationJinyang He
The type of the VMLINUX_LOAD_ADDRESS macro is the (unsigned long long) in 32bits kernel but (unsigned long) in the 64-bit kernel. Although there is no error here, avoid using it to calculate kaslr_offset. Signed-off-by: Jinyang He <hejinyang@loongson.cn> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2021-02-09MIPS: relocatable: Provide kaslr_offset() to get the kernel offsetJinyang He
Provide kaslr_offset() to get the kernel offset when KASLR is enabled. Error may occur before update_kaslr_offset(), so put it at the end of the offset branch.

2021-02-09usb: dwc3: gadget: Fix dep->interval for fullspeed interruptThinh Nguyen
The dep->interval captures the number of frames/microframes per interval from bInterval. Fullspeed interrupt endpoint bInterval is the number of frames per interval and not 2^(bInterval - 1). So fix it here. This change is only for debugging purpose and should not affect the interrupt endpoint operation.

2021-02-09staging: rtl8723bs: remove braces from two single line if blocksPhillip Potter
Remove braces from both occurences of single line if blocks in include/rtw_mlme.h, fixes two checkpatch warnings, thus clearing this type of warning from this file. Also swaps two if statement comparisons around, so the variable is on the left in each one. This fixes two warnings also.
