2010-10-25x86/oprofile: Fix uninitialized variable use in debug printkIngo Molnar
Stephen Rothwell reported this build warning: arch/x86/oprofile/op_model_amd.c: In function 'ibs_eilvt_valid': arch/x86/oprofile/op_model_amd.c:289: warning: 'offset' may be used uninitialized in this function And correctly observed that indeed the variable is used uninitialized in this function. The result of this bug can be a debug printk with a bogus value. Also fix a few more small details that made this function hard to read and which probably contributed to the bug being introduced to begin with: - Use more symmetric error conditions - Remove the !0 obfuscation - Add newlines to the printk output - Remove bogus linebreaks in printk strings and elsewhere Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Cc: Robert Richter <robert.richter@amd.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> LKML-Reference: <20101025115736.41d51abe.sfr@canb.auug.org.au> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2010-10-24IB/srp: Reduce number of BUSY conditionsBart Van Assche
As proposed by the SRP (draft) standard, ib_srp reserves one ring element for SRP_TSK_MGMT requests. This patch makes sure that the SCSI mid-layer never tries to queue more than (SRP request limit) - 1 SCSI commands to ib_srp. This improves performance for targets whose request limit is less than or equal to SRP_NORMAL_REQ_SQ_SIZE by reducing the number of BUSY responses reported by ib_srp to the SCSI mid-layer.

2010-10-24ACPI: Page based coalescing of I/O remappings optimizationMyron Stowe
This patch optimizes ACPI MMIO remappings by keeping track of the remappings on a PAGE_SIZE granularity. When an ioremap() occurs, the underlying infrastructure works on a 'page' based granularity. As such, an ioremap() request for 1 byte for example, will end up mapping in an entire (PAGE_SIZE) page. Huang Ying took advantage of this in commit 15651291a2f8c11e7e6a42d8bfde7a213ff13262 by checking if subsequent ioremap() requests reside within any of the list's existing remappings still in place, and if so, incrementing a reference count on the existing mapping as opposed to performing another ioremap().

2010-10-24ACPI: Pre-map 'system event' related register blocksMyron Stowe
During ACPI initialization, pre-map fixed hardware registers that are accessed during ACPI's 'system event' related IRQ handing. ACPI's 'system event' handing accesses specific fixed hardware registers; namely PM1a event, PM1b event, GPE0, and GPE1 register blocks which are declared within the FADT. If these registers are backed by MMIO, as opposed to I/O port space, accessing them within interrupt context will cause a panic as acpi_os_read_memory() depends on ioremap() in such cases - BZ 18012. By utilizing the functionality provided in the previous two patches - ACPI: Maintain a list of ACPI memory mapped I/O remappings, and, ACPI: Add interfaces for ioremapping/iounmapping ACPI registers - accesses to ACPI MMIO areas will now be safe from within interrupt contexts (IRQ and/or NMI) provided the area was pre-mapped. This solves BZ 18012. ACPI "System Event" reference(s): ACPI Specification, Revision 4.0, Section 3 "ACPI Overview", 3.8 "System Events", 5.6 "ACPI Event Programming Model".

2010-10-24ACPI: Add interfaces for ioremapping/iounmapping ACPI registersMyron Stowe
Add remapping and unmapping interfaces for ACPI registers that are backed by memory mapped I/O (MMIO). These interfaces, along with the MMIO remapping list, enable accesses of such registers from within interrupt context. ACPI Generic Address Structure (GAS) reference (ACPI's fixed/generic hardware registers use the GAS format): ACPI Specification, Revision 4.0, Section 5.2.3.1, "Generic Address Structure".

2010-10-24ACPI: Maintain a list of ACPI memory mapped I/O remappingsMyron Stowe
For memory mapped I/O (MMIO) remappings, add a list to maintain the remappings and augment the corresponding mapping and unmapping interface routines (acpi_os_map_memory() and acpi_os_unmap_memory()) to dynamically add to, and delete from, the list. The current ACPI I/O accessing methods - acpi_read() and acpi_write() - end up calling ioremap() when accessing MMIO. This prevents use of these methods within interrupt context (IRQ and/or NMI), since ioremap() may block to allocate memory. Maintaining a list of MMIO remappings enables accesses to such areas from within interrupt context provided they have been pre-mapped.

2010-10-24ACPI: Fix ioremap size for MMIO reads and writesMyron Stowe
The size used for I/O remapping MMIO read and write accesses has not accounted for the basis of ACPI's Generic Address Structure (GAS) 'Register Bit Width' field which is bits, not bytes. This patch adjusts the ioremap() 'size' argument accordingly. ACPI "Generic Register" reference: ACPI Specification, Revision 4.0, Section 5.2.3.1, "Generic Address Structure".

2010-10-25mmc: make number of mmcblk minors configurableOlof Johansson
The old limit of number of minor numbers per mmcblk device was hardcoded at 8. This isn't enough for some of the more elaborate partitioning schemes, for example those used by Chrome OS. Since there might be a bunch of systems out there with static /dev contents that relies on the old numbering scheme, let's make it a build-time option with the default set to the previous 8. Also provide a boot/modprobe-time parameter to override the config default: mmcblk.perdev_minors.

RAW writes were broken by 782ce79a45b3b850b108896fcf7da26754061c8f which introduced a check of ops->ooboffs in nand_do_write_ops(). When writing in RAW mode this is called with an ops struct on the stack of mtdchar.c:mtd_write() which does not initialise ops->ooboffs, so it is garbage and fails this test. This test does not make sense if ops->oobbuf is NULL, which it is in the RAW write path, so include that in the test.
