[Xen-devel] Make grub error "too few arguments" with xen



Hi,

 

When I make grub with xen using the latest commit: e8b37e2c8de7570ca9a6c7ba874762d8c4ba9373,  I met error “too few arguments to function grub_create_loader_cmdline()”.

I saw the following commit tried to fix this error, but we still met such error with the latest commit e8b37e2c8de7:

commit 25e35377a84779ceeb350aa530e5adde287f6eb6

    arm64/xen: Fix too few arguments to function grub_create_loader_cmdline()

 

    Without this fix, building xen_boot.c omits:

    loader/arm64/xen_boot.c:370:7: error: too few arguments to function ‘grub_create_loader_cmdline’
