  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
