[GIT PULL] Compute Express Link (CXL) Fixes for 6.18-rc2

[Dave Jiang <dave.jiang@intel.com>]

Hi Linus, please pull from

git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl.git tags/cxl-fixes-6.18-rc2

...to receive a small collection of CXL fixes. In addition to some misc fixes
for the CXL subsystem, a number of fixes for CXL extended linear cache support
are included to make it functional again.

While 0f6f1982cb28 ("cxl: Set range param for region_res_match_cxl_range() as const")
is not a fix, it's a small change that addresses a compile warning that arose from the fix
f4d027921c81 ("cxl: Fix match_region_by_range() to use region_res_match_cxl_range()").

These have all appeared in -next for a few days with no reported issues.

  cxl/trace: Subtract to find an hpa_alias0 in cxl_poison events (2025-10-14 14:48:14 -0700)

----------------------------------------------------------------
cxl fixes for v6.18-rc2

- Avoid missing port component registers setup due to dport enumeration
  failure
- Add check for no entries in cxl_feature_info to address accessing
  invalid pointer.
- Use %pa printk format to emit resource_size_t in
  validate_region_offset()

CXL extended linear cache support fixes:
- Fix setup of memory resource in cxl_acpi_set_cache_size()
- Set range param for region_res_match_cxl_range() as const.
  (Addresses a compile warning for match_region_by_range() fix)
- Fix match_region_by_range() to use region_res_match_cxl_range()
- Subtract to find an hpa_alias0 in cxl_poison events to correct
  the alias math calculation.
