2009-09-30sh: Disable unaligned kernel access printks by default.Paul Mundt1-2/+2

2009-09-28sparc64: Add a basic conflict engine in preparation for multi-counter support.David S. Miller1-5/+64
The hardware counter ->event_base state records and encoding of the "struct perf_event_map" entry used for the event. We use this to make sure that when we have more than 1 event, both can be scheduled into the hardware at the same time. As usual, structure of code is largely cribbed from powerpc.

2009-09-29sparc64: implement page mapping percpu first chunk allocatorTejun Heo2-9/+47
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.

2009-09-28sparc64: Increase vmalloc size to fix percpu regressions.David S. Miller2-6/+6
Since we now use the embedding percpu allocator we have to make the vmalloc area at least as large as the stretch can be between nodes. Besides some minor asm adjustments, this turned out to be pretty trivial. Signed-off-by: David S. Miller <[email protected]>
2009-09-28ARM: Ensure do_cache_op takes mmap_semRussell King1-1/+4
do_cache_op() uses find_vma() to validate its arguments without holding any locking. This means that the VMA could vanish beneath us. Fix this by taking a read lock on mmap_sem. Signed-off-by: Russell King <[email protected]>
2009-09-28ARM: Fix __cpuexit section mismatch warningsRussell King2-4/+6
Fix: WARNING: vmlinux.o(.text+0x247c): Section mismatch in reference from the function cpu_idle() to the function .cpuexit.text:cpu_die() The function cpu_idle() references a function in an exit section. Often the function cpu_die() has valid usage outside the exit section and the fix is to remove the __cpuexit annotation of cpu_die. WARNING: vmlinux.o(.cpuexit.text+0x3c): Section mismatch in reference from the function cpu_die() to the function .cpuinit.text:secondary_start_kernel() The function __cpuexit cpu_die() references a function __cpuinit secondary_start_kernel(). This is often seen when error handling in the exit function uses functionality in the init path. The fix is often to remove the __cpuinit annotation of secondary_start_kernel() so it may be used outside an init section. Sam says: > The annotation of cpu_die() is wrong. > To be annotated __cpuexit the function shall: > - be used in exit context and only in exit context with HOTPLUG_CPU=n > - be used outside exit context with HOTPLUG_CPU=y So, this also means __cpu_disable(), __cpu_die() and twd_timer_stop() are also wrong. However, removing __cpuexit from cpu_die() creates: WARNING: vmlinux.o(.text+0x6834): Section mismatch in reference from the function cpu_die() to the function .cpuinit.text:secondary_start_kernel() The function cpu_die() references the function __cpuinit secondary_start_kernel(). This is often because cpu_die lacks a __cpuinit annotation or the annotation of secondary_start_kernel is wrong. so fix this using __ref.

2009-09-28ARM: Don't allow highmem on SMP platforms without h/w TLB ops broadcastRussell King3-10/+50
We suffer an unfortunate combination of "features" which makes highmem support on platforms without hardware TLB maintainence broadcast difficult: - we need kmap_high_get() support for DMA cache coherence - this requires kmap_high() to take a spinlock with IRQs disabled - kmap_high() occasionally calls flush_all_zero_pkmaps() to clear out old mappings - flush_all_zero_pkmaps() calls flush_tlb_kernel_range(), which on s/w IPI'd systems eventually calls smp_call_function_many() - smp_call_function_many() must not be called with IRQs disabled: WARNING: at kernel/smp.c:380 smp_call_function_many+0xc4/0x240() Modules linked in: Backtrace: [<c00306f0>] (dump_backtrace+0x0/0x108) from [<c0286e6c>] (dump_stack+0x18/0x1c) r6:c007cd18 r5:c02ff228 r4:0000017c [<c0286e54>] (dump_stack+0x0/0x1c) from [<c0053e08>] (warn_slowpath_common+0x50/0x80) [<c0053db8>] (warn_slowpath_common+0x0/0x80) from [<c0053e50>] (warn_slowpath_null+0x18/0x1c) r7:00000003 r6:00000001 r5:c1ff4000 r4:c035fa34 [<c0053e38>] (warn_slowpath_null+0x0/0x1c) from [<c007cd18>] (smp_call_function_many+0xc4/0x240) [<c007cc54>] (smp_call_function_many+0x0/0x240) from [<c007cec0>] (smp_call_function+0x2c/0x38) [<c007ce94>] (smp_call_function+0x0/0x38) from [<c005980c>] (on_each_cpu+0x1c/0x38) [<c00597f0>] (on_each_cpu+0x0/0x38) from [<c0031788>] (flush_tlb_kernel_range+0x50/0x58) r6:00000001 r5:00000800 r4:c05f3590 [<c0031738>] (flush_tlb_kernel_range+0x0/0x58) from [<c009c600>] (flush_all_zero_pkmaps+0xc0/0xe8) [<c009c540>] (flush_all_zero_pkmaps+0x0/0xe8) from [<c009c6b4>] (kmap_high+0x8c/0x1e0) [<c009c628>] (kmap_high+0x0/0x1e0) from [<c00364a8>] (kmap+0x44/0x5c) [<c0036464>] (kmap+0x0/0x5c) from [<c0109dfc>] (cramfs_readpage+0x3c/0x194) [<c0109dc0>] (cramfs_readpage+0x0/0x194) from [<c0090c14>] (__do_page_cache_readahead+0x1f0/0x290) [<c0090a24>] (__do_page_cache_readahead+0x0/0x290) from [<c0090ce4>] (ra_submit+0x30/0x38) [<c0090cb4>] (ra_submit+0x0/0x38) from [<c0089384>] (filemap_fault+0x3dc/0x438) r4:c1819988 [<c0088fa8>] (filemap_fault+0x0/0x438) from [<c009d21c>] (__do_fault+0x58/0x43c) [<c009d1c4>] (__do_fault+0x0/0x43c) from [<c009e8cc>] (handle_mm_fault+0x104/0x318) [<c009e7c8>] (handle_mm_fault+0x0/0x318) from [<c0033c98>] (do_page_fault+0x188/0x1e4) [<c0033b10>] (do_page_fault+0x0/0x1e4) from [<c0033ddc>] (do_translation_fault+0x7c/0x84) [<c0033d60>] (do_translation_fault+0x0/0x84) from [<c002b474>] (do_DataAbort+0x40/0xa4) r8:c1ff5e20 r7:c0340120 r6:00000805 r5:c1ff5e54 r4:c03400d0 [<c002b434>] (do_DataAbort+0x0/0xa4) from [<c002bcac>] (__dabt_svc+0x4c/0x60) ...

2009-09-28sh: magicpanelr2 and dreamcast can use the generic I/O base.Paul Mundt2-4/+0

2009-09-28sh: Don't enable interrupts in the page fault pathMatt Fleming1-2/+0

2009-09-28sh: Set the default I/O port base to P2SEG.Paul Mundt1-0/+3
This bumps up the default I/O base to P2SEG, which allows legacy probing to bail out gracefully rather than oopsing. Platforms that have a real PIO offset still need to fix this up on their own, although most platforms are content with P2SEG already. The previous change to teach ioport_map() about >= P1SEG offsets in combination with this patch allows both the already remapped and the legacy address probing to pass through and succeed. Fixes up an oops with i8042 on the sh7785lcr board. Signed-off-by: Paul Mundt <[email protected]>
2009-09-28sh: Handle ioport_map() cases for >= P1SEG addresses.Paul Mundt1-0/+3
This fixes up the case where certain drivers already do their own remapping and subsequently attempt to use the PIO calls for I/O. In this case there is no additional remapping that needs to be done, and the address can be casted in to the cookie directly. Signed-off-by: Paul Mundt <[email protected]>

2009-09-27parisc: rename parisc's vmalloc_start to parisc_vmalloc_startHelge Deller2-7/+8
building kernel 2.6.32(pre), gives this compiler warning: /linus-linux-2.6/mm/vmalloc.c: In function 'pcpu_get_vm_areas': /linus-linux-2.6/mm/vmalloc.c:2104: warning: 'vmalloc_start' is used uninitialized in this function The reason is, that the code in mm/vmalloc defines a local variable called vmalloc_start, which is already defined as global variable in parisc's code.
