Reviewed-by: Jan Beulich <jbeul...@suse.com> with two remarks, though: While probably not very important yet for RISC-V (until there is at least enough functionality to, say, boot Dom0), you may want to get used to add Fixes: tags in cases like this one. > --- a/xen/arch/riscv/xen.lds.S > +++ b/xen/arch/riscv/xen.lds.S > @@ -137,6 +137,7 @@ SECTIONS > __init_end = .; > > .bss : { /* BSS */ > + . = ALIGN(POINTER_ALIGN); > __bss_start = .; > *(.bss.stack_aligned) > . = ALIGN(PAGE_SIZE); While independent of the change here, this ALIGN() visible in context is unnecessary, afaict. ALIGN() generally only makes sense when there's a linker-script-defined symbol right afterwards. Taking the case here, any contributions to .bss.page_aligned have to specify proper alignment themselves anyway (or else they'd be dependent upon linking order). Just like there's (correctly) no ALIGN(STACK_SIZE) ahead of *(.bss.stack_aligned). The change here might be a good opportunity to drop that ALIGN() at the same time. So long as you (and the maintainers) agree, I guess the adjustment could easily be made while committing. Jan
