Subject: [PATCH] powerpc: Sync hwcap.h with kernel
|
|
|
ce426f |
|
|
|
ce426f |
Linux commit b4b56f9ecab40f3b4ef53e130c9f6663be491894 introduced
|
|
|
ce426f |
a new HWCAP2 bit to indicate that the kernel now aborts a memory
|
|
|
ce426f |
transaction when a syscall is made. This patch adds that bit to
|
|
|
ce426f |
sysdeps/powerpc/bits/hwcap.h.

* sysdeps/powerpc/bits/hwcap.h: Add PPC_FEATURE2_HTM_NOSC.
|
|
|
ce426f |
* sysdeps/powerpc/dl-procinfo.c:
|
|
|
ce426f |
(_dl_powerpc_cap_flags): Added descriptor for this hwcap
|
|
|
ce426f |
feature so it shows when LD_SHOW_AUXV=1.
|

|
|
|
ce426f |
(cherry picked from commit 3c13f28c8eac1e5a883d1b3801314430a094fc99)
