* m68k/atari: ARAnyM - Fix NatFeat module supportGeert Uytterhoeven2013-09-101-4/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | commit e8184e10f89736a23ea6eea8e24cd524c5c513d2 upstream. As pointed out by Andreas Schwab, pointers passed to ARAnyM NatFeat calls should be physical addresses, not virtual addresses. Fortunately on Atari, physical and virtual kernel addresses are the same, as long as normal kernel memory is concerned, so this usually worked fine without conversion. But for modules, pointers to literal strings are located in vmalloc()ed memory. Depending on the version of ARAnyM, this causes the nf_get_id() call to just fail, or worse, crash ARAnyM itself with e.g. Gotcha! Illegal memory access. Atari PC = $968c This is a big issue for distro kernels, who want to have all drivers as loadable modules in an initrd. Add a wrapper for nf_get_id() that copies the literal to the stack to work around this issue.

* block: remove support for bio remapping from ->make_requestChristoph Hellwig2011-09-121-2/+1
| | | | | | | | | | | | | | | There is very little benefit in allowing to let a ->make_request instance update the bios device and sector and loop around it in __generic_make_request when we can archive the same through calling generic_make_request from the driver and letting the loop in generic_make_request handle it. Note that various drivers got the return value from ->make_request and returned non-zero values for errors.

* net: m68k/nfeth: Remove wrong usage of dev->flagsMichał Mirosław2011-07-141-1/+0
| | | | | | | | Remove wrong setting of dev->flags. NETIF_F_NO_CSUM maps to IFF_DEBUG there, so looks like a mistake. Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: David S. Miller <davem@davemloft.net>
