sparc idle: rename pm_idle to sparc_idle

2013-02-18T04:36:56+00:00

(pm_idle)() is being removed from linux/pm.h
because Linux does not have such a cross-architecture concept.

sparc uses an idle function pointer in its architecture
specific code.  So we re-name sparc use of pm_idle to sparc_idle.

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.

sparc32, copy_thread: Clear TIF_USEDFPU flag of created task instead of current

2012-07-26T23:49:40+00:00

FPU state is saved into task_struct of created task. Current task continues
use of the state, so it needs TIF_USEDFPU flag is not cleared.

Created task receives fresh FPU and cleared TIF_USEFPU flag is required for it.

sparc32: refactor cpu_idle()

2012-05-28T06:52:52+00:00

With the removal of sun4c we can use the same cpu_idle()
implementation on UP and SMP.
This also fix it so we use the same version independent on LEON
enabled or not.

V2: Fixed whitespace issue pointed out by Josip Rodin.

sparc32: drop btfixup for check_pgt_cache

2012-05-12T18:32:04+00:00

It is a noop for srmmu - so use a define as sparc64 does.
And drop all sparc callers - no need to confuse our-self
be calling a noop function.
