[1.] One line summary of the problem: Kernel 5.4.291 fails to build on i686 linux target due to problematic new code in x86/xen/mmu_pv.c [2.] Full description of the problem/report:
when building Kernel 5.4.291 under Lubuntu 18.6.6 LTS, with GCC 14.2, i686 target, build fails due to changes introduced in "arch/x86/xen/mmu_pv.c"
Note - I did not determined what of the following changes caused the issue:
Juergen Gross (1): x86/xen: allow larger contiguous memory regions in PV guests
Petr Tesarik (1): xen: remove a confusing comment on auto-translated guest I/O

[7.] A small shell script or example program which triggers the problem (if possible)
The problem only happens when building the kernel. I'm using this line for the build:
make bindeb-pkg LOCALVERSION=-i686-custom KDEB_PKGVERSION=$(make kernelversion)-1 -j8

[X.] Other notes, patches, fixes, workarounds:
I validated the changes from linux 5.4.29 vs 5.4.291 and saw that the changes were pretty much contained in mmu_pv.c.
meld ./linux-5.4.290/arch/x86/xen/mmu_pv.c ./linux-5.4.291/arch/x86/xen/mmu_pv.c
So in order to build the kernel 5.4.291, I just copied over mmu_pv.c file from 5.4.290 sources into 5.4.291 and I attempted to rebuild.
My 5.4.291 kernel was built successfully.
Best regards,
