[S390] Fix TCP/UDP pseudo header checksum computation.

2007-03-26T18:43:46+00:00

git commit f994aae1bd8e4813d59a2ed64d17585fe42d03fc changed the
function declaration of csum_tcpudp_nofold. Argument types were
changed from unsigned long to __be32 (unsigned int). Therefore we
lost the implicit type conversion that zeroed the upper half of the
registers that are used to pass parameters. Since the inline assembly
relied on this we ended up adding random values and wrong checksums
were created.
Showed only up on machines with more than 4GB since gcc produced code
where the registers that are used to pass 'saddr' and 'daddr' previously
contained addresses before calling this function.
Fix this by using 32 bit arithmetics and convert code to C, since gcc
produces better code than these hand-optimized versions.

[S390] reboot from and dump to SCSI under z/VM fails.

2007-03-19T12:19:03+00:00

We used wrong length values for ipl and dump hardware structures.
Since z/VM checks the ipl parameters more accurately than LPAR,
the operations fail there.

[S390] check_bugs() should be inline.

Don't have functions in header files unless they are inline.

[S390] reipl: move dump_prefix_page out of text section.

2007-03-05T22:35:43+00:00

Reipl doesn't work on older machines were s390_reset_machine() gets
called. The reason is that the text section is read-only but the
variable dump_prefix_page is there. Since s390_reset_machine() writes
to it we get a protection exception.
Therefore move dump_prefix_page to the bss section.

[S390] nss: Free unused memory in kernel image.

2007-02-21T09:55:37+00:00

With CONFIG_SHARED_KERNEL the kernel text segment that might be in a
read only memory sections starts at 1MB. Memory between 0x12000 and
0x100000 is unused then. Free this, so we have appr. an extra MB
of memory available.

[S390] New header file ipl.h

2007-02-21T09:55:21+00:00

Setup.h has been misused for ipl related stuff in the past. We now move
everything, which has to do with ipl and reipl to a new header file named
"ipl.h".
