mm: use vmf->address instead of of vmf->virtual_address

2016-12-15T00:04:09+00:00

Every single user of vmf->virtual_address typed that entry to unsigned
long before doing anything with it so the type of virtual_address does
not really provide us any additional safety.  Just use masked
vmf->address which already has the appropriate type.

mm: replace get_user_pages() write/force parameters with gup_flags

2016-10-19T15:11:43+00:00

This removes the 'write' and 'force' from get_user_pages() and replaces
them with 'gup_flags' to make the use of FOLL_FORCE explicit in callers
as use of this flag can result in surprising behaviour (and hence bugs)
within the mm subsystem.

x86/platform/UV: Remove Obsolete GRU MMR address translation

2016-05-04T06:48:51+00:00

Use no-op messages in place of cross-partition interrupts when nacking a
put message in the GRU.  This allows us to remove MMR's as a destination
from the GRU driver.

mm/gup: Switch all callers of get_user_pages() to not pass tsk/mm

2016-02-16T09:11:12+00:00

We will soon modify the vanilla get_user_pages() so it can no
longer be used on mm/tasks other than 'current/current->mm',
which is by far the most common way it is called.  For now,
we allow the old-style calls, but warn when they are used.
(implemented in previous patch)

This patch switches all callers of:

	get_user_pages()
	get_user_pages_unlocked()
	get_user_pages_locked()

to stop passing tsk/mm so they will no longer see the warnings.

misc: sgi-gru: fix return of error

2015-10-04T11:55:59+00:00

If kzalloc() fails then gms is NULL and we are returning NULL, but the
functions which called this function gru_register_mmu_notifier() are not
expecting NULL as the return. They are expecting either a valid pointer
or the error code in ERR_PTR.

misc: sgi-gru: gruhandles.c: Remove unused function

2015-10-04T11:55:59+00:00

Remove the function tfh_restart() that is not used anywhere.

This was partially found by using a static code analysis program called cppcheck.

To be future-proof and for better readability the time comparisons are
modified to use time_before() instead of plain, error-prone math.

drivers/misc/sgi-gru: fix possible NULL dereference

2015-09-21T02:33:29+00:00

If mmu_find_ops() returns NULL then we are allocating memory for gms
using kzalloc. But kzalloc can return NULL and we were dereferencing gms
in gru_dbg().
