2010-02-25mtd: fix different address space noiseH Hartley Sweeten
In mtd_ioctl MEMGETREGIONINFO the region_user_info pointer ur is cast in __kernel space. This produces a number of sparse warnings like: warning: cast removes address space of expression warning: incorrect type in initializer (different address spaces) expected unsigned int const [noderef] <asn:1>*register __p got unsigned int *<noident> Since argp is already a void __user * just use it dirrectly without the cast and make ur a __user *.

2010-02-25mtd: quiet sparse noise in cfi.hH Hartley Sweeten
In the inline function cfi_build_cmd_addr, the cast of cmd_ofs to an uint8_t produces a sparse warning of the type: warning: cast truncates bits from constant value (2aa becomes aa) Quiet the warning by masking cmd_ofs with 0xff and remove the cast.

2010-02-25mtd: mxc-nand: don't disable clock in mxcnd-suspendUwe Kleine-König
The clock must already be off after mtd->suspend. Disabling it again results in an negative overflow of the clock usage count. This didn't hurt as mxcnd_resume undid it after wake up.

2010-02-25mtd: mxc-nand: no need to check for validity of platform driver dataUwe Kleine-König
The probe function calls platform_set_drvdata with a valid pointer when the probe is successful. As mxcnd_suspend and mxcnd_resume are only called on bound devices, platform_get_drvdata always returns non-NULL. This fix isn't critical as the pointer is always valid so it doesn't matter if the compiler generated code for it or not.

Commit e99030609e27abff7e1a868cb56384c678b09984 ("mtd: orion_nand.c: add error handling and use resource_size()") introduced a build error -- it assigns something to a undeclared variable 'err', whereas the rest of the code uses 'ret' for this task.

2009-12-31kmsg_dump: Dump on crash_kexec as wellKOSAKI Motohiro
crash_kexec gets called before kmsg_dump(KMSG_DUMP_OOPS) if panic_on_oops is set, so the kernel log buffer is not stored for this case. This patch adds a KMSG_DUMP_KEXEC dump type which gets called when crash_kexec() is invoked. To avoid getting double dumps, the old KMSG_DUMP_PANIC is moved below crash_kexec(). The mtdoops driver is modified to handle KMSG_DUMP_KEXEC in the same way as a panic.

This introduces new bitmap functions: bitmap_set: Set specified bit area bitmap_clear: Clear specified bit area bitmap_find_next_zero_area: Find free bit area These are mostly stolen from iommu helper. The differences are: - Use find_next_bit instead of doing test_bit for each bit - Rewrite bitmap_set and bitmap_clear Instead of setting or clearing for each bit. - Check the last bit of the limit iommu-helper doesn't want to find such area - The return value if there is no zero area find_next_zero_area in iommu helper: returns -1 bitmap_find_next_zero_area: return >= bitmap size Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Cc: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Cc: "David S.

2009-12-16resource: constify arg to resource_size() and resource_type()Jean Delvare
resource_size() doesn't change the resource it operates on, so the res parameter can be marked const. Same for resource_type().

2009-12-16gru: send cross partition interrupts using the gruJack Steiner
GRU Message queue instructions are used to deliver messages to other SSIs within the numalink domain. In most cases, a single GRU mesq instruction will deliver both the message AND an interrupt to notify the other SSI that a messsage is present. In some cases, however, the interrupt must be sent explicitly. To improve resilency, the GRU driver should send these explicit interrupts using the GRU to write the remote chipset register. Current code sends the interrupt using a cpu instruction to write the chipset register.
