Pull bitmap updates from Yury Norov:

 - introduce for_each_set_bitrange()

 - use find_first_*_bit() instead of find_next_*_bit() where possible

 - unify for_each_bit() macros

  vsprintf: rework bitmap_list_string
  lib: bitmap: add performance test for bitmap_print_to_pagebuf
  bitmap: unify find_bit operations
  mm/percpu: micro-optimize pcpu_is_populated()
  Replace for_each_*_bit_from() with for_each_*_bit() where appropriate
  find: micro-optimize for_each_{set,clear}_bit()

  cpumask: replace cpumask_next_* with cpumask_first_* where appropriate
  tools: sync tools/bitmap with mother linux
  all: replace find_next{,_zero}_bit with find_first{,_zero}_bit where appropriate
  cpumask: use find_first_and_bit()
  lib: add find_first_and_bit()
  arch: remove GENERIC_FIND_FIRST_BIT entirely
  include: move find.h from asm_generic to linux
  bitops: move find_bit_*_le functions from le.h to find.h
  bitops: protect find_first_{,zero}_bit properly

all: replace find_next{,_zero}_bit with find_first{,_zero}_bit where appropriate

2022-01-15T16:47:31+00:00

find_first{,_zero}_bit is a more effective analogue of 'next' version if
start == 0. This patch replaces 'next' with 'first' where things look
trivial.

Pull MSI irq updates from Thomas Gleixner:
 "Rework of the MSI interrupt infrastructure.

  This is a treewide cleanup and consolidation of MSI interrupt handling
  in preparation for further changes in this area which are necessary
  to:

   - address existing shortcomings in the VFIO area

   - support the upcoming Interrupt Message Store functionality which
     decouples the message store from the PCI config/MMIO space"

The function has no users and is pointless now that the core frees the MSI
descriptors, which means potential users can just use msi_domain_free_irqs().

Protect the allocation properly and use the core allocation and free
mechanism.

No functional change intended.

device: Move MSI related data into a struct

2021-12-16T21:16:38+00:00

The only unconditional part of MSI data in struct device is the irqdomain
pointer. Everything else can be allocated on demand. Create a data
structure and move the irqdomain pointer into it. The other MSI specific
parts are going to be removed from struct device in later steps.

Since devm_ioremap_resource() function return error pointers.
The pktdma_get_regs() function does not return NULL, It return error
pointers too. Using IS_ERR() to check the return value to fix this.
