This changes symbols like HID0, SPRG3, SRR0, SRR1 etc. that refer to special purpose registers to SPRN_HID0, SPRN_SPRG3, etc. Using the SPRN_ symbols clutters the namespace less, and the forthcoming merge of asm/processor.h and asm/reg.h is going to remove the non-SPRN_ versions.

These days there is no good reason to run a ppc32 kernel on a 64-bit cpu, rather than a ppc64 kernel, so remove the config option and a bunch of code (and ifdefs) from head.S. Signed-off-by: NPaul Mackerras <paulus@samba.org>

This also creates merged versions of do_init_bootmem, paging_init and mem_init and moves them to arch/powerpc/mm/mem.c. It gets rid of the mem_pieces stuff. I made memory_limit a parameter to lmb_enforce_memory_limit rather than a global referenced by that function. This will require some small changes to ppc64 if we want to continue building ARCH=ppc64 using the merged lmb.c. Signed-off-by: NPaul Mackerras <paulus@samba.org>

This brings in the ppc64 version of prom_init.c, prom.c and btext.c and makes them work for ppc32. This also brings in the new calling convention, where the first entry to the kernel (with r5 != 0) goes to the prom_init code, which then restarts from the beginning (with r5 == 0) after it has done its stuff. For now this also brings in the ppc32 version of setup.c. It also merges lmb.h. Signed-off-by: NPaul Mackerras <paulus@samba.org>

This updates the powermac SMP code to use the mpic driver instead of the openpic driver and fixes the SMP-dependent context switch code. We had a subtle bug where we were using interrupt numbers 256-259 for IPIs, but ppc32 had NR_IRQS = 256. Moved the IPIs down to use interrupt numbers 252-255 instead.

The attached patch adds extra permission grants to keys for the possessor of a key in addition to the owner, group and other permissions bits. This makes SUID binaries easier to support without going as far as labelling keys and key targets using the LSM facilities. This patch adds a second "pointer type" to key structures (struct key_ref *) that can have the bottom bit of the address set to indicate the possession of a key. This is propagated through searches from the keyring to the discovered key. It has been made a separate type so that the compiler can spot attempts to dereference a potentially incorrect pointer. The "possession" attribute can't be attached to a key structure directly as it's not an intrinsic property of a key. Pointers to keys have been replaced with struct key_ref *'s wherever possession information needs to be passed through. This does assume that the bottom bit of the pointer will always be zero on return from kmem_cache_alloc(). The key reference type has been made into a typedef so that at least it can be located in the sources, even though it's basically a pointer to an undefined type. I've also renamed the accessor functions to be more useful, and all reference variables should now end in "_ref".

由 Alasdair G Kergon 提交于
When creating a multipath device, if the queue_if_no_path parameter is specified it gets ignored. While the queue_if_no_path variable is correctly set to 1, the saved_queue_if_no_path gets set to 0. When the device is subsequently made live (resumed), the saved value (0) always overwrites the live value (1) so the option *always* gets turned off. The fix adds a parameter to the queue_if_no_path() function to indicate whether the previous value should be preserved or not - if not, as when the device is being set up, the saved value is set to the new value (1).

This should resolve the issue seen in bugme bug #5105, where it is assumed that dualcore x86_64 systems have synced TSCs. This is not the case, and alternate timesources should be used instead. For more details, see: http://bugzilla.kernel.org/show_bug.cgi?id=5105 Andi's earlier concerns that the TSCs should be synced on dualcore systems have been resolved by confirmation from AMD folks that they can be unsynced.
