There is a race condition between ipa3_nat_init_cmd
and ipa_read_nat4. The two thread will R/W the critical
global variables. This will result in race conditions
and possibly buffer overread/ overwrite issues. Add code
to prevent this race condition.

Currently user regulatory hint is ignored if all wiphys
in the system are self managed. But the hint is not ignored
if there is no wiphy in the system. This affects the global
regulatory setting. Global regulatory setting needs to be
maintained so that it can be applied to a new wiphy entering
the system. Therefore, do not ignore user regulatory setting
even if all wiphys in the system are self managed.

Currently, the EDID parser adds the formats based on the
parsing of the Video data blocks and other CTA blocks.
However, there is no input validation based on the
HDMI HFVSDB block to check whether the mode advertised
by the sink actually falls in the TMDS char rate limits.
Add this check in the EDID parser to make sure invalid
formats are not added to the list.

This reverts commit 563b2f7a6b.
The previous approach of dynamically updating the writeable
permission bits of the power/data_role attributes only works
if the userspace application has root permission since the
call to sysfs_update_group() removes and re-adds the files. If
they had previously been chown/chgrp'ed, the ownership would be
reset. On the other hand, if there was a ueventd rule to
dynamically update the ownership, then the mode would always
be overridden with the static umask given in the ueventd rule,
contradicting the driver's determination of writeability.
Hence, the more comprehensive fix should be done in userspace
to not rely solely on writeability. Still, this change needs
to be reverted since it can still cause a race between ueventd
and the userspace service trying to check writability.

commit 6c26fcd2abfe0a56bbd95271fce02df2896cfd24 upstream.
pfn_modify_allowed() and arch_has_pfn_modify_check() are outside of the
!__ASSEMBLY__ section in include/asm-generic/pgtable.h, which confuses
assembler on archs that don't have __HAVE_ARCH_PFN_MODIFY_ALLOWED (e.g.
ia64) and breaks build:
include/asm-generic/pgtable.h: Assembler messages:
include/asm-generic/pgtable.h:538: Error: Unknown opcode `static inline bool pfn_modify_allowed(unsigned long pfn,pgprot_t prot)'
include/asm-generic/pgtable.h:540: Error: Unknown opcode `return true'

include/asm-generic/pgtable.h:545: Error: Unknown opcode `return false'
arch/ia64/kernel/entry.S:69: Error: `mov' does not fit into bundle
Move those two static inlines into the !__ASSEMBLY__ section so that they
don't confuse the asm build pass.
