2010-06-04omap: remove BUG_ON for disabled interruptsCory Maccarrone1-1/+0
Remove a BUG_ON for when interrupts are disabled during an MMC request. During boot, interrupts can be disabled when a request is made, causing this bug to be triggered. In reality, there's no reason this should halt the kernel, as the driver has proved reliable in spite of disabled interrupts, and additionally, there's nothing in this code that would require interrupts to be enabled. The only setup I've managed to make it trigger on is on the HTC Herald during bootup when the driver is built into the kernel (mostly because that's all I have). I believe it's related to the fact that on bootup I get many timeout errors on "CMD5" while initializing the card. Each CMD5 timeout triggers that bug (I changed it to a WARN_ON to get it to boot in) due to the fact that part of the timeout code involves sending the request again. With interrupts turned off, that BUG would be triggered.

Greg Thelen reported recent Johannes's stack diet patch makes kernel hang.

But the above patch changed to "return nr_reclaimed if .....". Oh, That forgot nr_reclaimed may be 0 if priority==0 reclaim failure. And Johannes's patch 0aeb2339e54e ("vmscan: remove all_unreclaimable scan control") made it more corrupt. Originally, priority==0 reclaim failure on memcg return 0, but this patch changed to return 1. It totally confused memcg. This patch fixes it completely.

The commit 80b5184cc537718122e036afe7e62d202b70d077 ("kernel/: convert cpu notifier to return encapsulate errno value") changed the return value of cpu notifier callbacks. Those callbacks don't return NOTIFY_BAD on failures anymore. But there are a few callbacks which are called directly at init time and checking the return value.

Commit f601441916d1e19291d0b4f044b4a7551e2924d0 ("imxfb: add support for i.MX25:) has inserted the symbol HAVE_FB_IMX, which does not depend on FB after the menuconfig FB. This breaks the menu, presenting most of the drivers outside of it, when using menuconfig. Moving the symbol to the start of the file, just like HAVE_FB_ATMEL, fixes the problem without breaking it for iMX25 configurations (tested with ARCH=arm, no build).

2010-06-04sys_personality: change sys_personality() to accept "unsigned int" instead ↵Oleg Nesterov3-11/+11
of u_long task_struct->pesonality is "unsigned int", but sys_personality() paths use "unsigned long pesonality". This means that every assignment or comparison is not right. In particular, if this argument does not fit into "unsigned int" __set_personality() changes the caller's personality and then sys_personality() returns -EINVAL. Turn this argument into "unsigned int" and avoid overflows. Obviously, this is the user-visible change, we just ignore the upper bits. But this can't break the sane application. There is another thing which can confuse the poorly written applications. User-space thinks that this syscall returns int, not long. This means that the returned value can be negative and look like the error code. But note that libc won't be confused and thus errno won't be set, and with this patch the user-space can never get -1 unless sys_personality() really fails. And, most importantly, the negative RET != -1 is only possible if that app previously called personality(RET).

The stack and data have different alignment requirements, so don't force them to wear the same shoe. Increase the data alignment to match that which the elf2flt linker script has always been using: 0x20 bytes. Not only does this bring the kernel loader in line with the toolchain, but it also fixes a swath of gcc tests which try to force larger alignment values but randomly fail when the FLAT loader fails to deliver.

A new buffer for a packet is created when a icmp packet is received. This happens in a context with disabled irq. Thus we are not allowed to sleep or call function which might sleep. kmalloc must be called with GFP_ATOMIC instead of GFP_KERNEL to ensure that it does not sleep.
