I assume no. I needed to get these long-term patches out there for the BGQ community for test. I would very much like to get a version of these upstream. I expect only the QPX, kexec, and (maybe) the DCR changes to cause any controversy, but I've been wrong before. I'll be making those patches soon and hope to get a lot of feedback from these patches. -jx > > Mikey > >> >> Here is a are the summary logs: >> >> $ git log --reverse linux-stable/linux-3.4.y.. >> commit 5a8edb2bdd914597693eed299119ff4c2e6d31f2 >> Author: Jimi Xenidis <ji...@pobox.com> >> Date: Fri Nov 9 09:26:00 2012 -0600 >> >> powerpc: Fix cputable #ifdef where CONFIG_PPC_A2 is used for >> CONFIG_PPC_BOOK3E_64 >> >> Signed-off-by: Jimi Xenidis <ji...@pobox.com> >> >> commit ea51920d7035c8d23801d6de46261e7d0a537dfd >> Author: Jimi Xenidis <ji...@pobox.com> >> Date: Fri Nov 9 08:58:27 2012 -0600 >> >> powerpc/book3e: Remove config for PPC_A2_DD2 since there is no reference >> to it >> >> This must have been leftover from early DD1 days which is not >> present in any current kernel code. >> >> Signed-off-by: Jimi Xenidis <ji...@pobox.com> >> >> commit 08151401a5db4ff0d441a1b7bf8ad92bd92b14c5 >> Author: Jimi Xenidis <ji...@pobox.com> >> Date: Mon Nov 5 09:38:01 2012 -0600 >> >> powerpc/dcr: Some native DCR fixes >> >> The following fixes have been made: >> - dcr_read/write_native() must use the indexed version of the >> m[ft]dcrx since the non-indexed version only allows a 10-bit >> numerical space, but the C interface allows a full 32-bits. >> - C bindings for m[ft]dcrx, and the "table" versions, should use >> "unsigned long" so that they are 64/32 bit neutral. >> - The "table" versions (__m[ft]cdr) should obtain the table address >> with LOAD_REG_ADDR(), this will also make it 64/32bit neutral. >> >> Signed-off-by: Jimi Xenidis <ji...@pobox.com> >> >> commit c8320a5daaceed03992d763302020834ea8e17dd >> Author: Jimi Xenidis <ji...@pobox.com> >> Date: Mon Nov 5 09:12:00 2012 -0600 >> >> powerpc/dcr: Add 64-bit DCR access methods. >> >> This patch adds the ability to make 64-bit Device Control Register >> (DCR) accesses. >> >> Signed-off-by: Jimi Xenidis <ji...@pobox.com> >> >> commit a763b3f8453b3bd83d7dded8c6644939863af430 >> Author: Jimi Xenidis <ji...@pobox.com> >> Date: Thu Nov 29 12:49:24 2012 -0500 >> >> powerpc/boot: Add a "spin_threads" hook to platform_ops >> >> It is useful for the boot program to arrange for all secondary cpus >> and threads to enter the kernel in a "kexec" fashion.
