2009-06-11sched: use kzalloc() instead of the bootmem allocatorPekka Enberg
Now that kmem_cache_init() happens before sched_init(), we should use kzalloc() and not the bootmem allocator. Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi>
2009-06-11init: introduce mm_init()Pekka Enberg
As suggested by Christoph Lameter, introduce mm_init() now that we initialize all the kernel memory allocations together. Cc: Christoph Lameter <cl@linux-foundation.org> Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi>
2009-06-11vmalloc: use kzalloc() instead of alloc_bootmem()Pekka Enberg
We can call vmalloc_init() after kmem_cache_init() and use kzalloc() instead of the bootmem allocator when initializing vmalloc data structures.

2009-06-11slab: setup allocators earlier in the boot sequencePekka Enberg
This patch makes kmalloc() available earlier in the boot sequence so we can get rid of some bootmem allocations. The bulk of the changes are due to kmem_cache_init() being called with interrupts disabled which requires some changes to allocator boostrap code. Note: 32-bit x86 does WP protect test in mem_init() so we must setup traps before we call mem_init() during boot as reported by Ingo Molnar: We have a hard crash in the WP-protect code: [ 0.000000] Checking if this processor honours the WP bit even in supervisor mode...BUG: Int 14: CR2 ffcff000 [ 0.000000] EDI 00000188 ESI 00000ac7 EBP c17eaf9c ESP c17eaf8c [ 0.000000] EBX 000014e0 EDX 0000000e ECX 01856067 EAX 00000001 [ 0.000000] err 00000003 EIP c10135b1 CS 00000060 flg 00010002 [ 0.000000] Stack: c17eafa8 c17fd410 c16747bc c17eafc4 c17fd7e5 000011fd f8616000 c18237cc [ 0.000000] 00099800 c17bb000 c17eafec c17f1668 000001c5 c17f1322 c166e039 c1822bf0 [ 0.000000] c166e033 c153a014 c18237cc 00020800 c17eaff8 c17f106a 00020800 01ba5003 [ 0.000000] Pid: 0, comm: swapper Not tainted 2.6.30-tip-02161-g7a74539-dirty #52203 [ 0.000000] Call Trace: [ 0.000000] [<c15357c2>] ? printk+0x14/0x16 [ 0.000000] [<c10135b1>] ? do_test_wp_bit+0x19/0x23 [ 0.000000] [<c17fd410>] ? test_wp_bit+0x26/0x64 [ 0.000000] [<c17fd7e5>] ? mem_init+0x1ba/0x1d8 [ 0.000000] [<c17f1668>] ? start_kernel+0x164/0x2f7 [ 0.000000] [<c17f1322>] ? unknown_bootoption+0x0/0x19c [ 0.000000] [<c17f106a>] ? __init_begin+0x6a/0x6f Acked-by: Johannes Weiner <hannes@cmpxchg.org> Acked-by Linus Torvalds <torvalds@linux-foundation.org> Cc: Christoph Lameter <cl@linux-foundation.org> Cc: Ingo Molnar <mingo@elte.hu> Cc: Matt Mackall <mpm@selenic.com> Cc: Nick Piggin <npiggin@suse.de> Cc: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi>

2009-06-11kmemleak: Add kmemleak_alloc callback from alloc_large_system_hashCatalin Marinas
The alloc_large_system_hash function is called from various places in the kernel and it contains pointers to other allocated structures. It therefore needs to be traced by kmemleak. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

2009-06-11kmemleak: Add the base supportCatalin Marinas
This patch adds the base support for the kernel memory leak detector. It traces the memory allocation/freeing in a way similar to the Boehm's conservative garbage collector, the difference being that the unreferenced objects are not freed but only shown in /sys/kernel/debug/kmemleak. Enabling this feature introduces an overhead to memory allocations.

2009-06-11sierra: driver interface blacklistingElina Pasheva
Interface blacklisting is necessary for non-serial interfaces that are handled by a different driver. The interface blacklisting is implemented in sierra driver per device. Each device in need of a blacklist has a static information array kept in the driver. This array contains the interface numbers that are blacklisted. The pointer for each blacklist array and the length of that blacklist are 'bundled' in data structure sierra_iface_info. A pointer to this information is set in id_table when the device is added to the id_table. The following is summary of changes we have made to sierra.c driver in this patch dealing with interface blacklisting support: - Added data structure sierra_iface_info and function is_blacklisted() to support blacklisting - Modified sierra_probe() to handle blacklisted interfaces accordingly - Improved comments in id_table - Added new device in id_table with blacklist interface support Signed-off-by: Elina Pasheva <epasheva@sierrawireless.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-06-11sierra: driver urb handling improvementsElina Pasheva
[Folded from eight patches into one as the original set according to the author "All of the patches need to be applied to obtain a working product" so keeping them split seems unhelpful Merge fixes done versus other conflicting changes and moved the spin_lock_init from open to setup time -- Alan] Summary of the changes and code re-organization in this patch: - The memory for urbs is allocated and urbs are submitted only for the active interfaces (instead of pre-allocating these for all interfaces). This will save memory especially in the case of using composite devices. - The code has been re-organized and functionality has been extracted from sierra_startup(), sierra_shutdown(), sierra_open(), sierra_close() and added in helper functions sierra_release_urb(), sierra_stop_rx_urbs(), sierra_submit_rx_urbs() and sierra_setup_urb() - Added function sierra_release_urb() to free an urb and its transfer buffer. - Removed unecessary include file reference and comment. - Added function sierra_stop_rx_urbs() that takes care of the release of receive and interrupt urbs. This function is to be called by sierra_close() whenever an interface is de-activated. - Added new function sierra_submit_rx_urbs() that handles the submission of receive urbs and interrupt urbs (if any) during the interface activation. This function is to be called by sierra_open(). Added a second parameter to pass the memory allocation (as suggested by Oliver Neukum) so that this function can be used in post_reset() and resume(). - Added new function sierra_setup_urb() that contains the functionality to allocate an urb, fill bulk urb using the supplied memory allocation flag and release urb upon error. Added parameter so that the caller pass the memory allocation flag for flexibility. - Moved sierra_close() before sierra_open() to resolve dependencies introduced by the code reorganization. - Modified sierra_close() to call sierra_stop_rx_urbs() and sierra_release_urb() functions added in previous patch. - Modified sierra_open() to call sierra_setup_urb() and sierra_submit_rx_urbs() functions; note urbs are allocated and submitted for each activated interface. - Modified sierra_startup() so that allocation of urbs happens whenever an interface is activated (urb allocation is moved to sierra_open()). - Modified sierra_shutdown() so that urbs are freed whenever an interface is de-activated (urb freeing moved to sierra_close() as shown in previous patch from the series) - Removed unecessary data structure from sierra_port_private_data - Suppress an entry in logs by not re-submitting an urb when usb_submit_urb() returns -EPERM, as this shows that usb_kill_urb() is running (as suggested by Oliver Neukum) Signed-off-by: Elina Pasheva <epasheva@sierrawireless.com> Signed-off-by: Alan Cox <alan.cox@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
