Subject: [GIT PULL] x86 fixes

Linus,

Please pull the latest x86/urgent git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-urgent-2022-08-06

   # HEAD: de979c83574abf6e78f3fa65b716515c91b2613d x86/entry: Build thunk_$(BITS) only if CONFIG_PREEMPTION=y

Misc fixes:

 - an old(er) binutils build fix,
 - a new-GCC build fix,
 - and a kexec boot environment fix.

NOTE, there's a new conflict in arch/x86/um/Makefile, due to these two 
commits interacting:

  upstream:      # 5b301409e8bc UML: add support for KASAN under x86_64
                 # adds two new targets to the single subarch-y line

  x86/urgent:    # de979c83574a x86/entry: Build thunk_$(BITS) only if CONFIG_PREEMPTION=y
                 # splits the ../entry/thunk_64.o target from the subarch-y line

it's a context conflict only, my resolution was:

  subarch-y = ../lib/csum-partial_64.o ../lib/memcpy_64.o ../lib/memmove_64.o ../lib/memset_64.o
  subarch-$(CONFIG_PREEMPTION) += ../entry/thunk_64.o

Thanks,

	Ingo
