If we use jump table in module init, there are marked as removed in __jump_table section after init is done. But we already applied ro permissions on the module, so we can't modify a read only section (crash in remove_jump_label_module_init). Make the __jump_table section rw.

2011-01-23m68k/amiga: Fix "debug=mem"Geert Uytterhoeven1-9/+7
`debug=mem' on Amiga has been broken for a while. early_param() processing is done very/too early, i.e. before amiga_identify() / amiga_chip_init(), causing amiga_savekmsg_setup() not to find any Chip RAM. As we don't plan to free this memory anyway, just steal it from the initial Chip RAM memory block instead. Signed-off-by: Geert Uytterhoeven <[email protected]>

2011-01-22m68k: Uninline strchr()Geert Uytterhoeven1-12/+0
Some versions of gcc replace calls to strstr() with single-character "needle" string parameters by calls to strchr() behind our back. If strchr() is defined as an inline function, this causes linking errors like ERROR: "strchr" [drivers/target/target_core_mod.ko] undefined! As m68k is the only architecture that has an inline strchr() and this inline version is not an optimized asm version, uninline strchr() and use the standard out-of-line C version in lib/string.c instead. This also decreases the defconfig/allmodconfig kernel image sizes by a few hundred bytes. Signed-off-by: Geert Uytterhoeven <[email protected]>
2011-01-21x86, hotplug: Fix powersavings with offlined cores on AMDBorislav Petkov3-2/+5
ea53069231f9317062910d6e772cca4ce93de8c8 made a CPU use monitor/mwait when offline. This is not the optimal choice for AMD wrt to powersavings and we'd prefer our cores to halt (i.e. enter C1) instead. For this, the same selection whether to use monitor/mwait has to be used as when we select the idle routine for the machine. With this patch, offlining cores 1-5 on a X6 machine allows core0 to boost again.

2011-01-21xen: p2m: correctly initialize partial p2m leafStefan Bader1-1/+19
After changing the p2m mapping to a tree by commit 58e05027b530ff081ecea68e38de8d59db8f87e0 xen: convert p2m to a 3 level tree and trying to boot a DomU with 615MB of memory, the following crash was observed in the dump: kernel direct mapping tables up to 26f00000 @ 1ec4000-1fff000 BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<c0107397>] xen_set_pte+0x27/0x60 *pdpt = 0000000000000000 *pde = 0000000000000000 Adding further debug statements showed that when trying to set up pfn=0x26700 the returned mapping was invalid. pfn=0x266ff calling set_pte(0xc1fe77f8, 0x6b3003) pfn=0x26700 calling set_pte(0xc1fe7800, 0x3) Although the last_pfn obtained from the startup info is 0x26700, which should in turn not be hit, the additional 8MB which are added as extra memory normally seem to be ok. This lead to looking into the initial p2m tree construction, which uses the smaller value and assuming that there is other code handling the extra memory. When the p2m tree is set up, the leaves are directly pointed to the array which the domain builder set up. But if the mapping is not on a boundary that fits into one p2m page, this will result in the last leaf being only partially valid. And as the invalid entries are not initialized in that case, things go badly wrong. I am trying to fix that by checking whether the current leaf is a complete map and if not, allocate a completely new page and copy only the valid pointers there. This may not be the most efficient or elegant solution, but at least it seems to allow me booting DomUs with memory assignments all over the range.
