Review new patches and attendee requested reviews.

 * State NEW delegate NOBODY 217 patches
 * Switching to discussing ABI blockers for release.
 * ABI issues for glibc 2.36
  * arc4random
  * Loongarch
 * [codonell] Kernel syscalls we would add?
  * azanella: Checked to 5.17.
  * Latest two releases may have new syscalls.
  * What about libiouring? Don't want to be tied to libc itself.
 * The 5.19 rc3/4 for kernel ABI is in place for Loongarch.
 * [v8] Add arc4random support (Series 10509)
  * Florian will look at this.
 * [v6] LoongArch (13 patches)
  * fweimer: Is upstream binutils ready?
  * azanella: Built cross toolchain and it looks ready (2.38)
  * fweimer: Upstream binutils issues:
   * https://sourceware.org/pipermail/libc-alpha/2022-July/140458.html
  * azanella: Want a committed upstream binutils and gcc.
   * codonell: Agree, want a committed linux, gcc, and binutils.
  * codonell: Will reach out to Nick Clifton to review LoongArch.
 * patrick: Can we submit regression fixes during the freeze?
  * codonell: Yes, we can fix bugs up until the release.
 * Update miscellaneous files from upstream sources (azanella)
  * Needs review. Built many arches and it was OK.
  * fweimer: config.guess/config.sub
 * elf.h: Add ELFCOMPRESS_ZSTD (fangrui)
  * Not a release blocker.
  * Blocked on Generic ABI or GNU ABI accepting.
 * x86-64: Remove redundant strcspn-generic/strpbrk-generic/strspn-generic
  * Reviewed by Noah.
 * [PATCHv3] Apply asm redirections in stdio.h before first use [BZ #27087]
  * With clang with long double == float128.
  * When Fedora was updated to clang14 we ran into this issue.
  * codonell: Not a release blocker *yet* because upstream defaults don't fail.
 * [1/7] Use atomic_exchange_release/acquire (Wilco)
  * codonell: Impact on aarch64? Can we wait until after the branch?
  * szabolcs: I think so.
 * Stopped at 55764.
 * Any patches to raise?
 * soft-fp: Add fixhf[uns][di|si] and float[uns][di|si]hf
  * codonell: Are we the canonical place for soft-fp?
  * Check with Joseph Myers about canonical place for soft-fp.
  * szabolcs: Confirmed. glibc is upstream.
  * Needs review.
 * 55628 [PATCHv3] tst-pidfd.c: UNSUPPORTED if we get EPERM on pidfd_open or pidfd_getfd
  * Rejected.
  * codonell: I'll respond again.
 * fweimer: Noted that Joseph Myers builder has been failing.
  * https://sourceware.org/pipermail/libc-testresults/2022q3/009939.html
  * Looks like BMG check fails.
  * Using mainline.
  * codonell: Uses mainline gcc builds which won't impact glibc until January.
  * fweimer: Could mask other issues.
