2009-10-02ia64: convert to dynamic percpu allocatorTejun Heo
Unlike other archs, ia64 reserves space for percpu areas during early memory initialization. These areas occupy a contiguous region indexed by cpu number on contiguous memory model or are grouped by node on discontiguous memory model. As allocation and initialization are done by the arch code, all that setup_per_cpu_areas() needs to do is communicating the determined layout to the percpu allocator. This patch implements setup_per_cpu_areas() for both contig and discontig memory models and drops HAVE_LEGACY_PER_CPU_AREA. Please note that for contig model, the allocation itself is modified only to allocate for possible cpus instead of NR_CPUS. As dynamic percpu allocator can handle non-direct mapping, there's no reason to allocate memory for cpus which aren't possible.

2009-10-02ia64: allocate percpu area for cpu0 like percpu areas for other cpusTejun Heo
cpu0 used special percpu area reserved by the linker, __cpu0_per_cpu, which is set up early in boot by head.S. However, this doesn't guarantee that the area will be on the same node as cpu0 and the percpu area for cpu0 ends up very far away from percpu areas for other cpus which cause problems for congruent percpu allocator. This patch makes percpu area initialization allocate percpu area for cpu0 like any other cpus and copy it from __cpu0_per_cpu which now resides in the __init area. This means that for cpu0, percpu area is first setup at __cpu0_per_cpu early by head.S and then moved to an area in the linear mapping during memory initialization and it's not allowed to take a pointer to percpu variables between head.S and memory initialization.

2009-10-02ia64: initialize cpu maps earlyTejun Heo
All information necessary to initialize cpu possible and present maps are available once early_acpi_boot_init() is complete. Reorganize setup_arch() and acpi init functions such that, * CPU information is printed after LAPIC entries are parsed in early_acpi_boot_init(). * smp_build_cpu_map() is called by setup_arch() instead of acpi functions. * smp_build_cpu_map() is called once all CPU related information is available before memory is initialized. This is primarily to allow find_memory() to use cpu maps but is also a general cleanup. Please note that with this change, the somewhat ad-hoc early_cpu_possible_map defined and used for NUMA configurations is probably unnecessary. Something to clean up another day.

2009-10-02ia64: don't alias VMALLOC_END to vmalloc_endTejun Heo
If CONFIG_VIRTUAL_MEM_MAP is enabled, ia64 defines macro VMALLOC_END as unsigned long variable vmalloc_end which is adjusted to prepare room for vmemmap. This becomes probnlematic if a local variables vmalloc_end is defined in some function (not very unlikely) and VMALLOC_END is used in the function - the function thinks its referencing the global VMALLOC_END value but would be referencing its own local vmalloc_end variable. There's no reason VMALLOC_END should be a macro. Just define it as an unsigned long variable if CONFIG_VIRTUAL_MEM_MAP is set to avoid nasty surprises.

2009-10-01s3cmci: add better support for no card detect or write protect availableBen Dooks
Add better support for omitting either the card detect or the write protect GPIOs if the board does not support it. Add the fields no_wprotect and no_detect to the platform data which when set indicate the absence of the respective GPIOs. Note, this also fixes a minor bug where it tries to free IRQ0 if there is no detect gpio available.

2009-10-01x86: fix csum_ipv6_magic asm memory clobberSamuel Thibault
Just like ip_fast_csum, the assembly snippet in csum_ipv6_magic needs a memory clobber, as it is only passed the address of the buffer, not a memory reference to the buffer itself. This caused failures in Hurd's pfinetv4 when we tried to compile it with gcc-4.3 (bogus checksums).

cmpxchg64() today generates, to quote Linus, "barf bag" code. cmpxchg64() is about to get used in the scheduler to fix a bug there, but it's a prerequisite that cmpxchg64() first be made non-sucking. This patch turns cmpxchg64() into an efficient implementation that uses the alternative() mechanism to just use the raw instruction on all modern systems. Note: the fallback is NOT smp safe, just like the current fallback is not SMP safe. (Interested parties with i486 based SMP systems are welcome to submit fix patches for that.)

The definition of the irq_ipi structure has two initializations of the flags field. This combines them. [Ralf: The issue was originally introduced by commit be4894196d79455f420dd7bb78be7dc73bec115c (linux-mips.org) rsp. 033890b084adfa367c544864451d7730552ce8bf (kernel.org). The original intention of the code was to initialize .flags with both flags ored together. The broken C code as actually implemented will be compiled by an equally broken gcc to use only the last initialization, that is IRQF_PERCPU which means this turned into an SMTC bug for 2.6.23 and newer.] The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier I, s, fld; position p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @s@ identifier I, s, r.fld; position r.p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @script:python@ p0 << r.p0; fld << r.fld; ps << s.p; pr << r.p; @@ if int(ps[0].line)!=int(pr[0].line) or int(ps[0].column)!=int(pr[0].column): cocci.print_main(fld,p0) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Implement page mapping percpu first chunk allocator as a fallback to the embedding allocator. The next patch will make the embedding allocator check distances between units to determine whether it fits within the vmalloc area so that this fallback can be used on such cases. sparc64 currently has relatively small vmalloc area which makes it impossible to create any dynamic chunks on certain configurations leading to percpu allocation failures. This and the next patch should allow those configurations to keep working until proper solution is found. While at it, mark pcpu_cpu_distance() with __init.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-2.6: sparc64: vio: Kill BUILD_BUG_ON() in vio_dring_avail(). Trivial conflict in arch/sparc/include/asm/vio.h due to David removing the whole messy BUG_ON that was confused.

Commit 200b812d00 "Clear the exclusive monitor when returning from an exception" broke the vast majority of ARM systems in the wild which are still pre ARMv6. The kernel is crashing on the first occurrence of an exception due to the removal of the actual return instruction for them. Let's add it back.

2009-09-25mips: fix build of vmlinux.ldsManuel Lauss
Commit 51b563fc93c8cb5bff1d67a0a71c374e4a4ea049 ("arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0") removed a few CPPFLAGS with vital include paths necessary to build vmlinux.lds on MIPS, and moved the calculation of the 'jiffies' symbol directly to vmlinux.lds.S but forgot to change make ifdef/... to cpp macros.
