[PATCH v6 1/3] x86/paravirt: Move halt paravirt calls under CONFIG_PARAVIRT

by Vishal Annapurve

From: "Kirill A. Shutemov" <kirill.shutemov(a)linux.intel.com> CONFIG_PARAVIRT_XXL is mainly defined/used by XEN PV guests. For other VM guest types, features supported under CONFIG_PARAVIRT are self sufficient. CONFIG_PARAVIRT mainly provides support for TLB flush operations and time related operations. For TDX guest as well, paravirt calls under CONFIG_PARVIRT meets most of its requirement except the need of HLT and SAFE_HLT paravirt calls, which is currently defined under CONFIG_PARAVIRT_XXL. Since enabling CONFIG_PARAVIRT_XXL is too bloated for TDX guest like platforms, move HLT and SAFE_HLT paravirt calls under CONFIG_PARAVIRT. Moving HLT and SAFE_HLT paravirt calls are not fatal and should not break any functionality for current users of CONFIG_PARAVIRT.

[PATCH v2 RESEND] phy: Fix error handling in tegra_xusb_port_init

by Ma Ke

If device_add() fails, do not use device_unregister() for error handling. device_unregister() consists two functions: device_del() and put_device(). device_unregister() should only be called after device_add() succeeded because device_del() undoes what device_add() does if successful. Change device_unregister() to put_device() call before returning from the function. As comment of device_add() says, 'if device_add() succeeds, you should call device_del() when you want to get rid of it. If device_add() has not succeeded, use only put_device() to drop the reference count'. Found by code review.

[PATCH v5 RESEND] [ARM] fix reference leak in locomo_init_one_child()

by Ma Ke

Once device_register() failed, we should call put_device() to decrement reference count for cleanup. Or it could cause memory leak. As comment of device_register() says, 'NOTE: _Never_ directly free @dev after calling this function, even if it returned an error! Always use put_device() to give up the reference initialized in this function instead.' Found by code review.

[PATCH] dlm: fix lkb timeout scanning lookup

by Alexander Aring

If a lkb is timed out when dlm_scan_timeout() kicks in and removes a timed out lkb from ls->ls_timeout list the next iteration can end in timeout the same lkb again that shouldn't happen. Since commit dc1acd5c9469 ("dlm: replace usage of found with dedicated list iterator variable") we don't set the lkb variable before the inner lookup loop to NULL. The outer loop will not stop and checks if there was a successful lookup with the lkb pointer of the last iteration that wasn't set to NULL. To stop this behavior we use the old condition "!do_cancel && !do_warn" which signals if there was a successful lookup and the lkb variable should be set with the lkb that was looked up to be timed out. If the condition is false there is no timed out lkb in ls->ls_timeout and the outer loop stops.
