x86/traps: Fix #DE Oops message regression
The conversion of #DE to the idtentry mechanism introduced a change in the
Ooops message which confuses tools which parse crash information in dmesg.
Remove the underscore from 'divide_error' to restore previous behaviour.

GPIO bulk changes for the v5.10 kernel cycle:
Core changes: - The big core change is the updated (v2) userspace character device API. This corrects badly designed 64-bit alignment around the line events. We also add the debounce request feature. This echoes the often quotes passage from Frederick Brooks "The mythical man-month" to always throw one away, which we have seen before in things such as V4L2.

We have some interesting cooperative work for ARM and Intel alike, making the GPIO subsystem more and more suitable for industrial systems and the like, in addition to the in-kernel users. We touch driver core (device properties) and lib/* by adding one simple string array free function, these are authored by Andy Shevchenko who is a well known and recognized core helpers maintainers so this should be fine. We also see some Android GKI-related modularization in the MXC drivers. Core changes: - The big core change is the updated (v2) userspace character device API. This corrects badly designed 64-bit alignment around the line events. We also add the debounce request feature. This echoes the often quotes passage from Frederick Brooks "The mythical man-month" to always throw one away, which we have seen before in things such as V4L2.

x86/uaccess: utilize CONFIG_CC_HAS_ASM_GOTO_OUTPUT
Clang-11 shipped support for outputs to asm goto statments along the fallthrough path. Double up some of the get_user() and related macros to be able to take advantage of this extended GNU C extension. This should help improve the generated code's performance for these accesses.

x86: Make __put_user() generate an out-of-line call
Instead of inlining the stac/mov/clac sequence (which also requires individual exception table entries and several asm instruction alternatives entries), just generate "call __put_user_nocheck_X" for the __put_user() cases, the same way we changed __get_user earlier. Unlike the get_user() case, we didn't have the same nice infrastructure to just generate the call with a single case, so this actually has to change some of the infrastructure in order to do this. But that only cleans up the code further. So now, instead of using a case statement for the sizes, we just do the same thing we've done on the get_user() side for a long time: use the size as an immediate constant to the asm, and generate the asm that way directly. In order to handle the special case of 64-bit data on a 32-bit kernel, I needed to change the calling convention slightly: the data is passed in %eax[:%edx], the pointer in %ecx, and the return value is also returned in %ecx. It used to be returned in %eax, but because of how %eax can now be a double register input, we don't want mix that with a single-register output. The actual low-level asm is easier to handle: we'll just share the code between the checking and non-checking case, with the non-checking case jumping into the middle of the function. That may sound a bit too special, but this code is all very very special anyway, so...

x86: Make __get_user() generate an out-of-line call
Instead of inlining the whole stac/lfence/mov/clac sequence (which also requires individual exception table entries and several asm instruction alternatives entries), just generate "call __get_user_nocheck_X" for the __get_user() cases. We can use all the same infrastructure that we already do for the regular "get_user()", and the end result is simpler source code, and much simpler code generation. It also means that when I introduce asm goto with input for "unsafe_get_user()", there are no nasty interactions with the __get_user() code.

This tree introduces static_call(), which is the idea of static_branch()
applied to indirect function calls. Remove a data load (indirection) by modifying the text. They give the flexibility of function pointers, but with better performance. (This is especially important for cases where retpolines would otherwise be used, as retpolines can be pretty slow.) API overview: DECLARE_STATIC_CALL(name, func); DEFINE_STATIC_CALL(name, func); DEFINE_STATIC_CALL_NULL(name, typename); static_call(name)(args...); static_call_cond(name)(args...); static_call_update(name, func); x86 is supported via text patching, otherwise basic indirect calls are used, with function pointers. There's a second variant using inline code patching, inspired by jump-labels, implemented on x86 as well. The new APIs are utilized in the x86 perf code, a heavy user of function pointers, where static calls speed up the PMU handler by 4.2% (!). The generic implementation is not really excercised on other architectures, outside of the trivial test_static_call_init() self-test.

Orphan link sections were a long-standing source of obscure bugs,
because the heuristics that various linkers & compilers use to handle them (include these bits into the output image vs discarding them silently) are both highly idiosyncratic and also version dependent.

EFI changes for v5.10:
- Preliminary RISC-V enablement - the bulk of it will arrive via the RISCV tree. - Relax decompressed image placement rules for 32-bit ARM - Add support for passing MOK certificate table contents via a config table rather than a EFI variable. - Add support for 18 bit DIMM row IDs in the CPER records. - Work around broken Dell firmware that passes the entire Boot#### variable contents as the command line - Add definition of the EFI_MEMORY_CPU_CRYPTO memory attribute so we can identify it in the memory map listings. - Don't abort the boot on arm64 if the EFI RNG protocol is available but returns with an error - Replace slashes with exclamation marks in efivarfs file names - Split efi-pstore from the deprecated efivars sysfs code, so we can disable the latter on !x86. - Misc fixes, cleanups and updates.

This allows printk() to store multiple timestamps in the ringbuffer which is useful for coordinating dmesg information across a fleet of machines. - Provide a multi-timestamp accessor for printk() - Make timer init more robust by checking for invalid timer flags. - Comma vs. semicolon fixes Drivers: - Support for new platforms in existing drivers (SP804 and Renesas CMT) - Comma vs. semicolon fixes -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl+ETs4THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoY/SEACva6YyL5F+GWT3aq1JBkQm55I0BSTS KD6XKeT765c88wB+CGzi/huYtSlL9lUonZ+8h2x/Yd9ObYEBqKANWUpzbPFM3aMd 5UbUHE9rIAbkAm7Ry1/GAQHVLCI/qYXZwaWDi37iHIplXwgY5jSr8AbqHsSBqM92 e1GMrLo6dxKqVhqPmHYCiZYPNH/15KIgzzrM8Mx7/pxHZaF7rSF/sjFAQObb4UOM 3ec9dqaKLAmQD04gHG5Y0YDttqHtii1+Gzqi9886Sv9xIvlM020J4elrKQqFnuV3 GGXRL4Rkhr4rXCJlYYTxE+7kQ7SVQDaztnQEqQCYMi8+DlmsdZsVUU3stsIA8SoF T6cC94g0ngoGbtA9Eb+WDT4eIlRPO+Ah/CsMnt78DkgNkI5Vc6U4cVrsWmGUtUDC oi/5gJeM8gP/UIzA+N+n3NNpQjC6PaVS0wIQQt/wOpBY6v9GOrcLxwJCpMujW8XG th8hXxANimAnyrI4osQhiYrY1zLnmJ7QB1PuuTkb8tyipGg+xkX68qD+oi6tKW+v Fo+aMbxv5sadyEA/yqxKLTpnTaVG7bexqrnkFBOxzBS2l3/WLXG4rWN/xYhDWAnm 4xc5lDOEwSGKk+saU9rs4x1TsLi02Fn++DwuGV0GIqT0qPX+jWsNpVTwE43epaDO Cpw7Cx+iGqsfkg== =h6YX -----END PGP SIGNATURE----- Merge tag 'timers-core-2020-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timekeeping updates from Thomas Gleixner: "Updates for timekeeping, timers and related drivers: Core: - Early boot support for the NMI safe timekeeper by utilizing local_clock() up to the point where timekeeping is initialized.

A small set of updates for debug objects:
- Make all debug object descriptors constant. There is no reason to have them writeable. - Free the per CPU object pool after CPU unplug to avoid memory waste. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl+EMM8THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYobvLD/95P1eqk5Hku2uHeHowj9t4PVqk68Gq 71rJTj/x32JnGVsNFfwoqm0u8CueAitT1Id5aIjiMAGK2eH83StwdfqFjdHsitwl 4zH6qywjjgq86jOSXXUQ2TSyYjlL7l2Pr8jwEZkTXUrShZyHAOvD9oW3KwlyV88H QXiTGFAm4aAaFctgGlbVafxtp1IJkS+FzFT1/cyPV064d3uGjX6maKwKjssO/8Bv WLzPuyOKh7IoEMfyFEXw3Ks3GK3Fo9Rkm4+CNLxjWy7DX7tY2Xvu4kuPqQ0dyn31 zzxJHOESLOjtw8w0vSEKpuNyIfL/66/MF8p4CXzkUWQTa9h26yos+mDnSzxth++d ZERCpx7udTG3BbteJ8ZEf3/QyH6kJw9RccDET180/CvhBTHELEsroy9qOfDMJkgt RODtwh+2+O0zqUGjbqEd+PTmkU5p0UwIWAI9t7pic5Dntse7stRwotDtI0FGNnF1 aj/4ZkTb+lq3EF/x9xh6Hw/SfcVGtmySeMaPlaj9fgq39dtTPIspYeI5GieZlE0s 1ZfoRSgWA+/K9+4iTsuGvTwXnLhsRYVZl+GIkzeG2FL3euK0t+vaIvIbE9IDHdsS mgEFaUXwIosHOfn+8f9KWl6YupBtT/4PyPVu5DseREl4up0W6s26aamM1Ml16A8x JUNS/oa+cGpI4A== =BP3+ -----END PGP SIGNATURE----- Merge tag 'core-debugobjects-2020-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull debugobjects updates from Thomas Gleixner: "A small set of updates for debug objects: - Make all debug object descriptors constant.
