2007-06-01Work around Dell E520 BIOS reboot bugTim Gardner
Force Dell E520 to use the BIOS to shutdown/reboot. I have at least one report that this patch fixes shutdown/reboot problems on the Dell E520 platform. (Andi says: People can always set the boot option. It hardly seems like a critical issue needing a backport.)

2007-06-01x86: fix oprofile double freeChris Wright
Chuck reports that the recent fix from Andi to oprofile 6c977aad03a18019015035958c65b6729cd0574c introduces a double free. Each cpu's cpu_msrs is setup to point to cpu 0's, which causes free_msrs to free cpu 0's pointers for_each_possible_cpu. Rather than copy the pointers, do a deep copy instead.

2007-06-01x86_64: allocate sparsemem memmap above 4GZou Nan hai
On systems with huge amount of physical memory, VFS cache and memory memmap may eat all available system memory under 4G, then the system may fail to allocate swiotlb bounce buffer. There was a fix for this issue in arch/x86_64/mm/numa.c, but that fix dose not cover sparsemem model. This patch add fix to sparsemem model by first try to allocate memmap above 4G.

2007-05-31PCI: i386: fixup for Siemens Nixdorf AG FSC Multiprocessor Interrupt ControllersIvan Kokshaysky
Wolfgang gets: PCI: Cannot allocate resource region 0 of device 0000:00:04.0 PCI: Error while updating region 0000:00:04.0/0 (a8008000 != fec08000) Note that the BAR seems to have high address bits hardwired to fec00000. And device 0000:00:04.0 is 00:04.0 System peripheral: Siemens Nixdorf AG FSC Multiprocessor Interrupt Controller (rev 02) I'd guess that when we try to reassign this resource, PCI interrupts might just stop working. This could explain SCSI timeouts and other weird things.

2007-05-29sparc64: fix alignment bug in linker definition scriptSam Ravnborg
The RO_DATA section were hardcoded to a specific alignment in include/asm-generic/vmlinux.h. But for sparc64 this did not match the PAGE_SIZE. Introduce a new section definition named: RO_DATA that takes actual alignment as parameter. RODATA are provided for backward compatibility. On top of this avoid hardcoding alignment for sparc64 in reset of the script Fix is build-tested on sparc64 + x86_64. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2007-05-29[SPARC64]: Fill holes in hypervisor APIs and fix KTSB registry.David S. Miller
Several interfaces were missing and others misnumbered or improperly documented. Also, make sure to check the return value when registering the kernel TSBs with the hypervisor. This helped to find the 4MB kernel TSB alignment bug fixed in a previous changeset. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-05-29[SPARC64]: Fix two bugs wrt. kernel 4MB TSB.David S. Miller
1) The TSB lookup was not using the correct hash mask. 2) It was not aligned on a boundary equal to it's size, which is required by the sun4v Hypervisor. wasn't having it's return value checked, and that bug will be fixed up as well in a subsequent changeset.

2007-05-29[SPARC]: Mark as emulating cmpxchg, add appropriate depends for DRM.Martin Habets
The DRM code depends on an atomic version of cmpxchg(), which is not available on sparc32. Since other platforms besides sparc32 have this issue a KCONFIG option is added for it. Signed-off-by: Martin Habets <errandir_news@mph.eclipse.co.uk> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-05-29[SPARC64]: Fix _PAGE_EXEC_4U check in sun4u I-TLB miss handler.David S. Miller
It was using an immediate _PAGE_EXEC_4U value in an 'and' instruction to perform the test. This doesn't work because the immediate field is signed 13-bit, this the mask being tested against the PTE was 0x1000 sign-extended to 32-bits instead of just plain 0x1000. Signed-off-by: David S.

This is bug 8540 on bugzilla.kernel.org arch/sparc64/time.c contains references to assorted bq4802 stuff if CONFIG_PCI is not set, and compile fails. I #ifdef'ed out everything that looks PCI-ish in that file. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-05-29[SPARC64]: Eliminate NR_CPUS limitations.David S. Miller
Cheetah systems can have cpuids as large as 1023, although physical systems don't have that many cpus. Only three limitations existed in the kernel preventing arbitrary NR_CPUS values: 1) dcache dirty cpu state stored in page->flags on D-cache aliasing platforms. With some build time calculations and some build-time BUG checks on page->flags layout, this one was easily solved. 2) The cheetah XCALL delivery code could only handle a cpumask with up to 32 cpus set. Some simple looping logic clears that up too. 3) thread_info->cpu was a u8, easily changed to a u16. There are a few spots in the kernel that still put NR_CPUS sized arrays on the kernel stack, but that's not a sparc64 specific problem. Signed-off-by: David S. Miller <davem@davemloft.net>
