      exfat: Avoid allocating upcase table using kcalloc() · 9eb78c25
      Artem Labazov authored 
      The table for Unicode upcase conversion requires an order-5 allocation,
which may fail on a highly-fragmented system:

      Pull clk updates from Stephen Boyd:
 "The core framework got some nice improvements this time around. We
  gained the ability to get struct clk pointers from a struct clk_hw so
  that clk providers can consume the clks they provide, if they need to
  do something like that. This has been a long missing part of the clk
  provider API that will help us move away from exposing a struct clk
  pointer in the struct clk_hw. Tracepoints are added for the
  clk_set_rate() "range" functions, similar to the tracepoints we
  already have for clk_set_rate() and we added a column to debugfs to
  help developers understand the hardware enable state of clks in case
  firmware or bootloader state is different than what is expected.
  Overall the core changes are mostly improving the clk driver writing
  experience.

  At the driver level, we have the usual collection of driver updates
  and new drivers for new SoCs. This time around the Qualcomm folks
  introduced a good handful of clk drivers for various parts of three or
  four SoCs. The SiFive folks added a new clk driver for their FU740
  SoCs, coming in second on the diffstat and then Atmel AT91 and Amlogic
  SoCs had lots of work done after that for various new features. One
  last thing to note in the driver area is that the i.MX driver has
  gained a new binding to support SCU clks after being on the list for
  many months. It uses a two cell binding which is sort of rare in clk
  DT bindings. Beyond that we have the usual set of driver fixes and
  tweaks that come from more testing and finding out that some
  configuration was wrong or that a driver could support being built as
  a module.

  Summary:

  Core:
   - Add some trace points for clk_set_rate() "range" functions
   - Add hardware enable information to clk_summary debugfs
   - Replace clk-provider.h with of_clk.h when possible
   - Add devm variant of clk_notifier_register()
   - Add clk_hw_get_clk() to generate a struct clk from a struct clk_hw

  New Drivers:
   - Bindings for Canaan K210 SoC clks
   - Support for SiFive FU740 PRCI
   - Camera clks on Qualcomm SC7180 SoCs
   - GCC and RPMh clks on Qualcomm SDX55 SoCs
   - RPMh clks on Qualcomm SM8350 SoCs
   - LPASS clks on Qualcomm SM8250 SoCs

  Updates:
   - DVFS support for AT91 clk driver
   - Update git repo branch for Renesas clock drivers
   - Add camera (CSI) and video-in (VIN) clocks on Renesas R-Car V3U
   - Add RPC (QSPI/HyperFLASH) clocks on Renesas RZ/G2M, RZ/G2N, and RZ/G2E
   - Stop using __raw_*() I/O accessors in Renesas clk drivers
   - One more conversion of DT bindings to json-schema
   - Make i.MX clk-gate2 driver more flexible
   - New two cell binding for i.MX SCU clks
   - Drop of_match_ptr() in i.MX8 clk drivers
   - Add arch dependencies for Rockchip clk drivers
   - Fix i2s on Rockchip rk3066
   - Add MIPI DSI clks on Amlogic axg and g12 SoCs
   - Support modular builds of Amlogic clk drivers
   - Fix an Amlogic Video PLL clock dependency
   - Samsung Kconfig dependencies updates for better compile test coverage
   - Refactoring of the Samsung PLL clocks driver
   - Small Tegra driver cleanups
   - Minor fixes to Ingenic and VC5 clk drivers
   - Cleanup patches to remove unused variables and plug memory leaks"

      Pull KVM updates from Paolo Bonzini:
 "Much x86 work was pushed out to 5.12, but ARM more than made up for it.

  ARM:
   - PSCI relay at EL2 when "protected KVM" is enabled
   - New exception injection code
   - Simplification of AArch32 system register handling
   - Fix PMU accesses when no PMU is enabled
   - Expose CSV3 on non-Meltdown hosts
   - Cache hierarchy discovery fixes
   - PV steal-time cleanups
   - Allow function pointers at EL2
   - Various host EL2 entry cleanups
   - Simplification of the EL2 vector allocation

  s390:
   - memcg accouting for s390 specific parts of kvm and gmap
   - selftest for diag318
   - new kvm_stat for when async_pf falls back to sync

  x86:
   - Tracepoints for the new pagetable code from 5.10
   - Catch VFIO and KVM irqfd events before userspace
   - Reporting dirty pages to userspace with a ring buffer
   - SEV-ES host support
   - Nested VMX support for wait-for-SIPI activity state
   - New feature flag (AVX512 FP16)
   - New system ioctl to report Hyper-V-compatible paravirtualization features

  Generic:
   - Selftest improvements"
