alpha: Fixup last users of irq_chip->typename

2009-12-01T03:51:31+00:00

The typename member of struct irq_chip was kept for migration purposes
and is obsolete since more than 2 years. Fix up the leftovers.

Alpha: Rearrange thread info flags fixing two regressions

2009-12-01T03:44:40+00:00

The removal of the TIF_NOTIFY_RESUME flag, commit a583f1b54249b
"remove unused TIF_NOTIFY_RESUME flag," resulted in incorrect
setting of the unaligned access control flags by the prctl syscall.

The re-addition of the TIF_NOTIFY_RESUME flag, commit d0420c83f39f
"KEYS: Extend TIF_NOTIFY_RESUME to (almost) all architectures [try #6]"
further caused problems, namely incorrect operands to assembler code
as evidenced by:

AS      arch/alpha/kernel/entry.o
arch/alpha/kernel/entry.S: Assembler messages:
arch/alpha/kernel/entry.S:326: Warning: operand out of range
(0x0000000000000406 is not between 0x0000000000000000 and
0x00000000000000ff)

Both regressions fixed by (1) rearranging TIF_NOTIFY_RESUME flag to be
in lower 8 bits of the thread info flags, and (2) making sure that
ALPHA_UAC_SHIFT matches the rearrangement of the thread info flags.

arch/alpha/kernel: Add kmalloc NULL tests

2009-11-30T20:38:19+00:00

Check that the result of kmalloc is not NULL before passing it to other
functions.

The semantic match that finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// 
@@
expression *x;
identifier f;
constant char *C;
@@

x = \(kmalloc\|kcalloc\|kzalloc\)(...);
... when != x == NULL
    when != x != NULL
    when != (x || ...)

kfree(x)
f(...,C,...,x,...)
|
*f(...,x,...)

*x->f
)

arch/alpha/kernel/sys_ruffian.c: Use DIV_ROUND_CLOSEST

2009-11-30T20:37:25+00:00

The kernel.h macro DIV_ROUND_CLOSEST performs the computation (x + d/2)/d
but is perhaps more readable.

The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)

//

- (((x) + ((__divisor) / 2)) / (__divisor))

fcntl: Use consistent values for F_[GS]ETOWN_EX

2009-11-17T17:13:43+00:00

These values were only introduced during this release cycle, so it is
still early enough to get them right.

alpha uses the same values that are in asm-generic/fcntl.h, so just
remove them.

parisc uses the values interchanged for no apparent reason, so remove
them to give us consistency across all architectures.

alpha: move THREAD_SIZE definition outside #ifndef ASSEMBLY

arch/alpha/kernel/vmlinux.lds.S uses it:

arch/alpha/kernel/vmlinux.lds:241: undefined symbol `THREAD_SIZE' referenced in expression

    alpha: Clean up linker script using new linker script macros.

    Note that .data.page_aligned and .data.cacheline_aligned are now after
    _data; it was probably a bug that they were before it.

    Also, some explicit ALIGN(8)'s between various initcall sections were
    removed; this should be harmless as the implicit alignment of
    initcall_t was already 8.
