vfs: define struct filename and have getname() return it

2012-10-13T00:14:55+00:00

getname() is intended to copy pathname strings from userspace into a
kernel buffer. The result is just a string in kernel space. It would
however be quite helpful to be able to attach some ancillary info to
the string.

For instance, we could attach some audit-related info to reduce the
amount of audit-related processing needed. When auditing is enabled,
we could also call getname() on the string more than once and not
need to recopy it from userspace.

This patchset converts the getname()/putname() interfaces to return
a struct instead of a string. For now, the struct just tracks the
string in kernel space and the original userland pointer for it.

Later, we'll add other information to the struct as it becomes
convenient.

Revert "microblaze_mmu_v2: Update signal returning address"

2012-10-04T16:56:39+00:00

This reverts commit 8b28626a6b1522b39f75d0bf80d5dec23c931f5a.

Offset -8 is wrong because when it is applied then one instruction
before brki r14, 8 is called again when we return.
Offset -4 is correct and brki instruction is called again.

This change came from ancient MMU kernel.

microblaze: Fix bug with passing command line

2012-10-04T12:59:19+00:00

When u-boot passes control over to Linux it places the Linux command
line between to the end of __init_end. When space between
__init_end and __bss_start is not COMMAND_LINE_SIZE then
the part of cmdline can be lost.
In extreme case if __init_end == __bss_start u-boot can't pass
any cmdline to Linux kernel.

This patch fix this issue by copying cmd line directly to
cmd_line char array which is placed in data section.
