13 years ago[IA64] tidy up return value of ip_fast_csum
Chen, Kenneth W [Thu, 9 Nov 2006 00:29:25 +0000]
[IA64] tidy up return value of ip_fast_csum

While working on implementing csum_ipv6_magic, I noticed that current
version of ip_fast_csum will potentially return bits above "unsigned
short" as 1.  While no harm is done right now because all call sites
will chop off the upper bits when it uses the return value.  However,
this is still dangerous and buggy.  Here is a patch to enforce that the
function really returns unsigned short in the native register format.

The fix is free as there are plenty open slot to add one more asm instruction.

[PATCH] uclinux: fix mmap() of directory for nommu case

I was playing with blackfin when i hit a neat bug ... doing an open() on a
directory and then passing that fd to mmap() would cause the kernel to hang

after poking into the code a bit more, i found that
mm/nommu.c:validate_mmap_request() checks the length and if it is 0, just
returns the address ... this is in stark contrast to mmu's
mm/mmap.c:do_mmap_pgoff() where it returns -EINVAL for 0 length requests ...
i then noticed that some other parts of the logic is out of date between the
two funcs, so perhaps that's the easy fix ?

[PATCH] m68knommu: switch 68360 to using rtc_time

Adds support for RTCs (through genrtc) for M68KNOMMU.

Board-specific code will have to link the appropriate RTC driver to the
mach_hwclk callback, at minimum.

 - adds an ipr_idx to the ipr_data and uses a function in the subtype
   code to calculate the address of the IPR registers

 - adds a function to enable individual interrupt mode for externals
   in the subtype code and calls that from the titan board code
   instead of doing it directly.

 - I changed the shift in the ipr_data to be the actual # of bits to
   shift, instead of the numnber / 4 - made it easier to match with

shll8 reg

size without resorting to special instructions available in

sh: Configurable timer IRQ.

All of the various CPU subtypes currently hardcode TIMER_IRQ,
switch this to a config option in the few places we need this.

This allows further removal of hardcoded IRQ headers..

Jeff Garzik [Mon, 4 Dec 2006 01:49:23 +0000]
[SCSI] megaraid: fix MMIO casts

megaraid's MMIO RD*/WR* macros directly call readl() and writel() with
an 'unsigned long' argument.  This throws a warning, but is otherwise OK
because the 'unsigned long' is really the result of ioremap().  This
setup is also OK because the variable can hold an ioremap cookie /or/ a
PCI I/O port (PIO).

However, to fix the warning thrown when readl() and writel() are passed
an unsigned long cookie, I introduce 'void __iomem *mmio_base', holding
the same value as 'base'.  This will silence the warnings, and also
cause an oops whenever these MMIO-only functions are ever accidentally
passed an I/O address.

[PATCH] Centralise definitions of sector_t and blkcnt_t

CONFIG_LBD and CONFIG_LSF are spread into asm/types.h for no particularly
good reason.

Centralising the definition in linux/types.h means that arch maintainers
don't need to bother adding it, as well as fixing the problem with
x86-64 users being asked to make a decision that has absolutely no
effect.

The H8/300 porters seem particularly confused since I'm not aware of any
microcontrollers that need to support 2TB filesystems.
