ARC: add kmemleak support (2019-11-20 09:13:42 -0800)
----------------------------------------------------------------
ARC updates for 5.5-rc1
- 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
----------------------------------------------------------------
Eugeniy Paltsev (12):
ARC: regenerate nSIM and HAPS defconfigs
ARC: HAPS: cleanup defconfigs from unused IO-related options
ARC: HAPS: use same UART configuration everywhere
ARC: HAPS: add HIGHMEM memory zone to DTS
ARC: HAPS: cleanup defconfigs from unused ETH drivers
ARC: merge HAPS-HS with nSIM-HS configs
ARC: nSIM_700: switch to DW UART usage
ARC: nSIM_700: remove unused network options
ARC: ARCv2: jump label: implement jump label patching
ARC: [plat-axs10x]: use pgu pll instead of fixed clock
ARC: [plat-axs10x]: remove hardcoded video mode from bootargs
ARC: add kmemleak support
Vineet Gupta (6):
ARCv2: mm: TLB Miss optim: SMP builds can cache pgd pointer in mmu scratch reg
ARCv2: mm: TLB Miss optim: Use double world load/stores LDD/STD
ARC: mm: TLB Miss optim: avoid re-reading ECR
ARC: mm: tlb flush optim: Make TLBWriteNI fallback to TLBWrite if not available
ARC: mm: tlb flush optim: elide repeated uTLB invalidate in loop
ARC: mm: tlb flush optim: elide redundant uTLB invalidates for MMUv3
