Fix lpfc_parse_bg_err()'s use of do_div().  It should be passing a 64-bit
variable as the first parameter.  However, since it's only using a 32-bit

division operator.

If two writers allocating blocks to file race with each other (e.g.
because writepages races with ordinary write or two writepages race with
each other), ext2_getblock() can be called on the same inode in parallel.
Before we are going to allocate new blocks, we have to recheck the block
chain we have obtained so far without holding truncate_mutex.  Otherwise
we could overwrite the indirect block pointer set by the other writer
leading to data loss.

The below test program by Ying is able to reproduce the data loss with ext2
on in BRD in a few minutes if the machine is under memory pressure:

long kMemSize  = 50 << 20;
int kPageSize = 4096;

int main(int argc, char **argv) {
	int status;
	int count = 0;
	int i;
	char *fname = "/mnt/test.mmap";
	char *mem;
	unlink(fname);
	int fd = open(fname, O_CREAT | O_EXCL | O_RDWR, 0600);
	status = ftruncate(fd, kMemSize);
	mem = mmap(0, kMemSize, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0);
	// Fill the memory with 1s.
	memset(mem, 1, kMemSize);
	sleep(2);
	for (i = 0; i < kMemSize; i++) {
		int byte_good = mem[i] != 0;
		if (!byte_good && ((i % kPageSize) == 0)) {
			//printf("%d ", i / kPageSize);
			count++;
		}
	}
	munmap(mem, kMemSize);
	close(fd);
	unlink(fname);

	if (count > 0) {
		printf("Running %d bad page\n", count);
		return 1;
	}
	return 0;

SHMEM_MAX_BYTES was derived from the maximum size of its triple-indirect
swap vector, forgetting to take the MAX_LFS_FILESIZE limit into account.
Never mind 256kB pages, even 8kB pages on 32-bit kernels allowed files to
grow slightly bigger than that supposed maximum.

Fix this by using the min of both (at build time not run time).  And it
happens that this calculation is good as far as 8MB pages on 32-bit or
16MB pages on 64-bit: though SHMSWP_MAX_INDEX gets truncated before that,
it's truncated to such large numbers that we don't need to care.

Fix a division by zero which we have in shmem_truncate_range() and
shmem_unuse_inode() when using big PAGE_SIZE values (e.g.  256kB on
ppc44x).

With 256kB PAGE_SIZE, the ENTRIES_PER_PAGEPAGE constant becomes too large
(0x1.0000.0000) on a 32-bit kernel, so this patch just changes its type
from 'unsigned long' to 'unsigned long long'.

Hugh: reverted its unsigned long longs in shmem_truncate_range() and
shmem_getpage(): the pagecache index cannot be more than an unsigned long,
so the divisions by zero occurred in unreached code.  It's a pity we need
any ULL arithmetic here, but I found no pretty way to avoid it.
