Merge tag 'arc-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc
Pull ARC updates from Vineet Gupta - Jump Label support for ARC - kmemleak enabled - arc mm backend TLB Miss / flush optimizations - nSIM platform switching to dwuart (vs. arcuart) and ensuing defconfig updates and cleanups - axs platform pll / video-mode updates * tag 'arc-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc: ARC: add kmemleak support ARC: [plat-axs10x]: remove hardcoded video mode from bootargs ARC: [plat-axs10x]: use pgu pll instead of fixed clock ARC: ARCv2: jump label: implement jump label patching ARC: mm: tlb flush optim: elide redundant uTLB invalidates for MMUv3 ARC: mm: tlb flush optim: elide repeated uTLB invalidate in loop ARC: mm: tlb flush optim: Make TLBWriteNI fallback to TLBWrite if not available ARC: mm: TLB Miss optim: avoid re-reading ECR ARCv2: mm: TLB Miss optim: Use double world load/stores LDD/STD ARCv2: mm: TLB Miss optim: SMP builds can cache pgd pointer in mmu scratch reg ARC: nSIM_700: remove unused network options ARC: nSIM_700: switch to DW UART usage ARC: merge HAPS-HS with nSIM-HS configs ARC: HAPS: cleanup defconfigs from unused ETH drivers ARC: HAPS: add HIGHMEM memory zone to DTS ARC: HAPS: use same UART configuration everywhere ARC: HAPS: cleanup defconfigs from unused IO-related options ARC: regenerate nSIM and HAPS defconfigs
