[PATCH OLK-6.6] mm: set hugepage to false when anon mthp allocation
by Liu Shixin 20 Sep '24

20 Sep '24

From: Kefeng Wang <wangkefeng.wang(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IARA8A -------------------------------- When the hugepage parameter is true in vma_alloc_folio(), it indicates that we only try allocation on preferred node if possible, but it could lead to lots of failures for large folio allocation without commit ddc1a5cbc05d ("mempolicy: alloc_pages_mpol() for NUMA policy without vma"), it has no effect on runtime behavior on mainline, but we're affected, so fix it by setting hugepage to false.

[PATCH OLK-6.6] arm64/cpufeatures/kvm: Add ARMv8.9 FEAT_ECBHB bits in ID_AA64MMFR1 register

From: Nianyao Tang <tangnianyao(a)huawei.com> mainline inclusion from mainline-v6.11-rc1 commit e8cde32f111f7f5681a7bad3ec747e9e697569a9 category: other bugzilla: https://gitee.com/openeuler/kernel/issues/IAS9Z8 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git/commit/?id=… ------------------------------------------------------------------------------- Enable ECBHB bits in ID_AA64MMFR1 register as per ARM DDI 0487K.a specification. When guest OS read ID_AA64MMFR1_EL1, kvm emulate this reg using ftr_id_aa64mmfr1 and always return ID_AA64MMFR1_EL1.ECBHB=0 to guest. It results in guest syscall jump to tramp ventry, which is not needed in implementation with ID_AA64MMFR1_EL1.ECBHB=1. Let's make the guest syscall process the same as the host.
