Build 6.13-rc12 for x86_64 with gcc 14.2.1 fails with the error: ld: vmlinux.o: in function `virtual_mapped': linux/arch/x86/kernel/relocate_kernel_64.S:249:(.text+0x5915b): undefined reference to `saved_context_gdt_desc' when CONFIG_KEXEC_JUMP is enabled. This was introduced by commit07fa619f2a("x86/kexec: Restore GDT on return from ::preserve_context kexec") which introduced a use of saved_context_gdt_desc without a declaration for it. Fix that by including asm/asm-offsets.h where saved_context_gdt_desc is defined (indirectly in include/generated/asm-offsets.h which asm/asm-offsets.h includes).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
