Hi,
Tested these changes on top of my uapi headers fix branch and
they compile without problems in userspace and thus fix the original issue.
Also abi-compliance-checker reports that these changes don't break anything
in i386 ABI (details at [2]):
"Test Info
Library Name kernel
Version #1 headers_test_v04
Version #2 headers_test_v04+test_ingo_x86_cleanup
CPU Type x86
GCC Version 5.2.1
Subject Binary Compatibility
Test Results
Total Header Files 767
Total Shared Libraries 0 (not analyzed)
Total Symbols / Types 62 / 67
Verdict Compatible"
or API:
"Test Info
Library Name kernel
Version #1 headers_test_v04
Version #2 headers_test_v04+test_ingo_x86_cleanup
CPU Type x86
GCC Version 5.2.1
Subject Source Compatibility
Test Results
Total Header Files 767
Total Shared Libraries 0 (not analyzed)
Total Symbols / Types 96 / 101
Verdict Compatible"
While abi-compliance-checker is still quite broken with kernel header files[3]
addition of new constants was correctly detected:
"Other Changes in Constants (3)
sigcontext.h
[−] _fpstate
Change Effect
1 The constant _fpstate with value _fpstate_32 has been added. No effect.
[−] _fpstate_ia32
Change Effect
1 The constant _fpstate_ia32 with value _fpstate_32 has been added. No effect.
[−] sigcontext_ia32
Change Effect
1 The constant sigcontext_ia32 with value sigcontext_32 has been added. No effect."
So for 32 bit userspace side
