Fix the non-linear memory mapping done via remap_file_pages() -- it didn't work on any MIPS CPU because the page offset clashing with _PAGE_FILE and some other page protection bits which should have been left zeros for this kind of pages. Signed-off-by:

open() always sets the O_LARGEFILE flag for the o32 ABI implementation of a 64bit kernel. The appended patch fixes it. Signed-off-by:

Alchemy boards use YAMON which passes the environment variables as the tuples of strings (the name followed by the value) unlike PMON which passes "name=<val>" strings. Signed-off-by:

With 64-bit physical address enabled, 'swapon' was causing kernel oops on Alchemy CPUs (MIPS32) because of the swap entry type field corrupting the _PAGE_FILE bit in 'pte_low' field. So, switch to storing the swap entry in 'pte_high' field using all its bits except _PAGE_GLOBAL and _PAGE_VALID which gives 25 bits for the swap entry offset. Signed-off-by:

Save the Config.OD bit from being clobbered by coherency_setup(). This bit, when set, fixes various errata in the early steppings of Au1x00 SOCs. Unfortunately, the bit was write-only on the most early of them. In addition, also restore the bit after a wakeup from sleep. Signed-off-by:

Ivan Kokshaysky authored
From: Ivan Kokshaysky <ink@jurassic.park.msu.ru> After removal of fixup_cpu_present_map() function Alpha ended up with an empty cpu_present_map, so secondary CPUs on SMP systems are not being started. Worse, on some platforms we route interrupts to secondary CPUs using cpu_possible_map which is still populated properly. As a result, these interrupts go nowhere so the machines like DP264 aren't able to boot even with a primary CPU. Fixed basically by s/cpu_present_mask/cpu_present_map/. Thanks to Ernst Herzberg for reporting the bug and testing the fix. Cc: Ernst Herzberg <list-lkml@net4u.de> Cc: Richard Henderson <rth@twiddle.net> Signed-off-by:

* master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6: [SPARC64]: Fix missing fold at end of checksums.
-
Eli Cohen authored
When ipoib_stop() is called it first calls netif_stop_queue() to stop the kernel from passing more packets to the network driver. However, the completion handler may call netif_wake_queue() re-enabling packet transfer. This might result in leaks (we see AH leaks which we think can be attributed to this bug) as new packets get posted while the interface is going down. Signed-off-by:

David S. Miller authored
Both csum_partial() and the csum_partial_copy*() family of routines forget to do a final fold on the computed checksum value on sparc64. So do the standard Sparc "add + set condition codes, add carry" sequence, then make sure the high 32-bits of the return value are clear. Based upon some excellent detective work and debugging done by Richard Braun and Samuel Thibault. Signed-off-by:David S. Miller <davem@davemloft.net>
