[PATCH] bus/fslmc: use PRIu64 instead of llX in format specifier

[PATCH] bus/fslmc: use PRIu64 instead of llX in format specifier

[Gowrishankar]

From: Gowrishankar Muthukrishnan <gowrishankar.m@linux.vnet.ibm.com>

Instead of llX, use C99 standard "PRIu64" in format specifier. Former one
breaks compile in ppc64le.

Fixes: c2c167fdb3 ("bus/fslmc: support memory event callbacks for VFIO")

NACK

This is breaking the x86_64-native-linuxapp-gcc  compilation. I am 
looking into it.

So, powerpc64LE is taking __u64 as long unsigned int, while x86_64 
compiler is taking it as long long unsigned it.

You should also type cast the variables to avoid compilation issue on x86.
-                       dma_map.vaddr, dma_map.size);
+                       (uint64_t)dma_map.vaddr, uint64_t)dma_map.size);

The same change is to be done at other two places as well in your patch.

Please check compilation for x86_64 and i686, the patchwork compilation 
check is running late.

You cannot replace hexadecimal by decimal.
You need to use PRIx64.

Now that Thomas has pointed out, I think the log message can be 
improved. Len as hex is not helpful and is out of sync with other 
messages in this file.

While on this, I think it should be corrected.
I will fix this.

@gowrishankar, I will post a patch in reply to your patch - can you 
please help me with ppc64le check? I will take care of Hemant's comment.

[PATCH v3] bus/fslmc: use PRIu64 instead of llX in format specifier

[Gowrishankar]

From: Gowrishankar Muthukrishnan <gowrishankar.m@linux.vnet.ibm.com>

Instead of llX, use C99 standard "PRIu64" in format specifier. Former one
breaks compile in ppc64le.

Fixes: c2c167fdb3 ("bus/fslmc: support memory event callbacks for VFIO")

Signed-off-by: Gowrishankar Muthukrishnan <gowrishankar.m@linux.vnet.ibm.com>
--
v3:
 - correction to prefix address with 0x
v2:
 - corrected format specifier wrt address and size.
   Thanks Shreyansh, Hemant and Thomas.
