It seems you got some trailing spaces issues:

Applying: hugetlb: open-code hugetlb folio lookup index conversion
.git/rebase-apply/patch:64: trailing whitespace.
	pgoff_t index = start >> PAGE_SHIFT;

Applying: hugetlb: make hugetlb_fault_mutex_hash() take PAGE_SIZE index
.git/rebase-apply/patch:161: trailing whitespace.
	key[1] = index >> huge_page_order(hstate_inode(mapping->host));

Applying: hugetlb: drop vma_hugecache_offset() in favor of linear_page_index()
.git/rebase-apply/patch:44: trailing whitespace.
	start = linear_page_index(vma, vma->vm_start); 
.git/rebase-apply/patch:46: trailing whitespace.
	end = linear_page_index(vma, vma->vm_end);

Applying: hugetlb: pass hugetlb reservation ranges in base-page indices
.git/rebase-apply/patch:237: trailing whitespace.
		next_index = index + pages_per_huge_page(h)
