2012-05-09802: Convert compare_ether_addr to ether_addr_equalJoe Perches

2012-05-09percpu: pcpu_embed_first_chunk() should free unused parts after all allocs ↵Tejun Heo
are complete pcpu_embed_first_chunk() allocates memory for each node, copies percpu data and frees unused portions of it before proceeding to the next group. This assumes that allocations for different nodes doesn't overlap; however, depending on memory topology, the bootmem allocator may end up allocating memory from a different node than the requested one which may overlap with the portion freed from one of the previous percpu areas. This leads to percpu groups for different nodes overlapping which is a serious bug. This patch separates out copy & partial free from the allocation loop such that all allocations are complete before partial frees happen. This also fixes overlapping frees which could happen on allocation failure path - out_free_areas path frees whole groups but the groups could have portions freed at that point.

2012-05-09regmap: fix possible memory corruption in regmap_bulk_read()Laxman Dewangan
The function regmap_bulk_read() calls the regmap_read() for each register if set of register has volatile and cache is enabled. In this case, last few register read makes the memory corruption if the register size is not the size of unsigned int. The regam_read() takes argument as unsigned int for returning value and it update the value as *val = map->format.parse_val(map->work_buf); This causes complete 4 bytes (size of unsigned int) to get written. Now if client pass the memory pointer for value which is equal to the required size of register count in regmap_bulk_read() then last few register read actually update the memory beyond passed pointer size. Avoid this by using local variable for read and then do memcpy() for actual byte copy to passed pointer based on register size. I allocated one pointer ptr and take first 16 bytes dump of that pointer then call regmap_bulk_read() with pointer which is just on top of this allocated pointer and register count of 128. Here register size is 1 byte. The memory trace of last 5 register read are as follows: [ 5.438589] regmap_bulk_read after regamp_read() for register 122 [ 5.447421] 0xef993c20 0xef993c00 0x00000000 0x00000001 [ 5.467535] regmap_bulk_read after regamp_read() for register 123 [ 5.476374] 0xef993c20 0xef993c00 0x00000000 0x00000001 [ 5.496425] regmap_bulk_read after regamp_read() for register 124 [ 5.505260] 0xef993c20 0xef993c00 0x00000000 0x00000001 [ 5.525372] regmap_bulk_read after regamp_read() for register 125 [ 5.534205] 0xef993c00 0xef993c00 0x00000000 0x00000001 [ 5.554258] regmap_bulk_read after regamp_read() for register 126 [ 5.563100] 0xef990000 0xef993c00 0x00000000 0x00000001 [ 5.554258] regmap_bulk_read after regamp_read() for register 127 [ 5.587108] 0xef000000 0xef993c00 0x00000000 0x00000001 Here it is observed that the memory content at first word started changing on last 3 regmap_read() and so corruption happened.

2012-05-09ALSA: HDA: Lessen CPU usage when waiting for chip to respondDavid Henningsson
When an IRQ for some reason gets lost, we wait up to a second using udelay, which is CPU intensive. This patch improves the situation by waiting about 30 ms in the CPU intensive mode, then stepping down to using msleep(2) instead. In essence, we trade some granularity in exchange for less CPU consumption when the waiting time is a bit longer. As a result, PulseAudio should no longer be killed by the kernel for taking up to much RT-prio CPU time. At least not for *this* reason.

2012-05-08brcmfmac: add out of band interrupt supportFranky Lin
Some sdio host controllers do not support real in band interrupt. Software polling mode as a replacement is not fast enough for high throughput and new features. Also some in band interrupts do not support host wake up on embedded platform even when they are real physical interrupts. Therefore out of band (oob) interrupt mechanism is implemented for these scenarios. To provide oob irq number and flags used for irq registration in brcmfmac, a platform device contains irq resource must be registered in board specific code. Here is an example of platform device structure: struct resource brcmf_sdio_res[] = { { .start = GPIO_BRCMF_SDIO_OOB_NUM, .end = GPIO_BRCMF_SDIO_OOB_NUM, .flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL, } }; struct platform_device brcmf_sdio_device = { .name = "brcmf_sdio_pd", .id = -1, .num_resources = ARRAY_SIZE(brcmf_sdio_res), .resource = brcmf_sdio_res, }; Reviewed-by: pieter-paul giesberts <pieterpg@broadcom.com> Reviewed-by: arend van spriel <arend@broadcom.com> Signed-off-by: franky lin <frankyl@broadcom.com> Signed-off-by: Franky Lin <frankyl@broadcom.com> Signed-off-by: John W.

2012-05-08ipw2200: Fix order of device registrationBen Hutchings
Currently cfg80211 fails to create a "phy80211" symlink in sysfs from the net device to the wiphy device. The latter needs to be registered first. Compile-tested only.

2012-05-08rt2x00: Add debugfs access for rfcsr registerAnisse Astier
RFCSR is only used in rt2800. For other chipsets, the debug struct for rfcsr should be zeroed, which isn't be an issue, since the code can now cope with that.

Allow a register to be unspecified, therefore not creating its debugfs file entry. Signed-off-by: Anisse Astier <anisse@astier.eu> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

We separate device bring up and registration with network stack to avoid the problem. After that Ben Hutchings' fix can be applied to fix the bug.
